GeoCorder 1.1.0

Some time ago I got approached by a corporate customer who was looking for a solution to have his vehicles report their location to his server. Previously he had been using Nokia phones and now he was looking to switch to iPhones. So I built a quick app for him, but due to lack of multitasking in iOS 3 it had limited use. But then Apple surprised us with backgrounding for location apps and suddenly make apps like GeoCorder all the more useful.

But I did not think that this mini tracking app by itself would make a good addition to the app store, so I insisted of merging this functionality into GeoCorder. So now GeoCorder can record GPX tracks for photo tagging or viewing in Google Earth and can also ping your server with a customizable HTTP GET.

  • Background Recording on iOS 4
  • UI improvements
  • Completely rewritten backend with CoreData engine
  • FREE Version: iAds on iOS 4 Devices with AdMob fallback
  • User Guide and Support
  • Map View centering on current Location
  • Tracker Mode to ping corporate server with location updates

For the UI you might notice that I moved the recording controls into the navigation bar. Also this is now using a tab bar controller to switch between multiple views with differing functionality. I switched the tracks view and the recording view because for a recording app the recording screen obviously is the more important view.

Once I started to think about the functionality of this app I suddenly had my head fill will lots of additional things, most of which did not make the cut for what is supposed to be a minor upgrade that turned into a 4 day project. For example I had considered adding Google Latitude updating as a Tracking choice. But 1.1.0 is meant to give my customer (and other people with similar logistics use cases) a tool which he can easily install through the app store.

The problem with those many ideas is that nobody is paying for their implementation. On both the full and the free version (ads) I’m making like 10 Dollars a week. Only if I see a dramatic uptake in downloads I will be able to afford implementing more features. But I’m still interested to hear your thoughts should you be amongst those few people who have a use for this uncomplicated app.

Maybe it helps a bit that I am also targeting iOS 3.x which still is the OS of choice for iPhone 3G. Where I previously had only AdMob ads, I have now also iAds on iOS 4 devices with AdMob being the fallback. I’ll report on how that goes.

I just submitted the app to Apple for approval. I tested orders of magnitude more than before and eliminated all bugs that I could find to make this a really high quality release.

Update Aug 6th: The update has been approved. What’s a first is that the review team approved the update first and later wrote a mail to me asking to add a battery disclaimer to the iTunes description. Apparently all apps using background GPS are required to have this in the description:

“Continued use of GPS running in the background can dramatically decrease battery life.”

So I added it. Much obliged!

Update: I found two bugs in the free version for which I just submitted update 1.1.1: Ads could not be tapped on and I had forgotten to include background location support.

MyAppSales 1.0.16

Apple changed two column headings on the financial reports because apparently the June reports are the first ones which will also show eBook publishers their revenues.

  • “Artist/Show/Developer” became “Artist/Show/Developer/Author”
  • “Label/Studio/Network/Developer” became “Label/Studio/Network/Developer/Publisher”

There where quite a few hot fixes that I had to put into MyAppSales and also if you look at the code you’ll see that it’s in the middle of being migrated to CoreData. The latter is necessary because the current method of caching everything is really ugly code whereas CoreData will permit me to make the app perform way better and it only fetches data I truly need.

Unfortunately (or fortunately depending on how you look at it) I’m very busy with a major project for the last few months, so I cannot really muster the time right now to carry through this migration. But because this is a point of stability in MyAppSale’s live that I can publish it as a new version. Lots of people where continuing to use the previous “released” version because for some reason they feared that the “2.0 BETA” in the Subversion trunk might be unstable. When in reality it aways was the code I’ve been using on my iPhone.

Speaking of iPhone 4, you still need to build it with SDK 3.2 until further notice for exactly the reason I mentioned above: ugly caching. It works fine on my iPhone 4.

Here are some goodies that I also hacked into 1.0.16:

  • Ability to remove individual reports. For example if something goes wrong during download.
  • You can opt to show a report sum on the overview pages. This is slower because for it the app needs to fetch the sales data, so it will impact scrolling. But if you don’t scroll much then its a useful number to see at a glance.
  • I’m now using the standard currency formatter for all amounts

Please update your copy from the repository as usual.

How to make your Hybrid-App crash for sure

I was quite happy finally getting the new polished 1.1 version of SpeakerClock approved. But there was one problem: people who tried to run it on iPhones with iOS 3.1.3 started tweeting me that it crashes. I was astonished, I was not aware of using anything from 4.0, I just had to set the base SDK to 3.2 to support hybrid mode.

Then I tried out the update on my wife’s iPhone which I kept at the latest released iOS version, 3.1.3. And it crashed. So I hooked it up and had a look at the crash report. There’s something about “doesNotRecognizeSelector”. This means I am calling a method that the receiving object does not recognize. Uh Oh.

Newly published: iOdometer

Previously I explained how I am approaching iPhone development in a broad spectrum. The vehicle for my business is a company called Drobnik KG, or as I refer to it in IT context: drobnik.com.

We have a publishing contract with young Laurens whose apps are already making up a major portion of our daily sales. The agreement works like this: I’m taking care of the stresses with dealing with Apple, submitting the app and maintaining the SVN-server where the apps are being developed. For this convenience Laurens is sharing part of the profits with us.

And profits they are! Over the last half year this arrangement netted Laurens sufficient funds to buy a Mac. Thus invigorated he sat down and developed a distance measuring app: iOdometer. This, too, is selling far better than I might have guessed. So I refrain from making any future predictions concerning Laurens’ success. For some strange reason he seems to exactly hit the nerve of what people are willing to pay for.

Maybe that’s because of the high quality components from Dr. Touch’s Parts Store he implemented: DTLEDNumberView and DTMenuController. Being able to rely on their sturdiness and ease of implementation he was able to focus on the app’s main feature set and bring it to market in record time.

iOdometer is available on the app store. Version 1.1 has been submitted to Apple, it features better accuracy and a new icon. Other successful apps by Laurens are Frequency Annoyer and Full Screen Browser.

SpeakerClock 1.1

My previous article covering an iPhone-to-Universal migration inspired me so much that I spent two days on getting the HD-upgrade for SpeakerClock ready to ship.

Changes

  • Universal app, runs on iPhone and on iPad in native resolution
  • Portrait Mode, now all orientations are supported
  • Now screen flashes in the appropriate color when threshold to yellow or red is passed
  • In-App Purchase for 5 presets instead of one
  • Lot’s of minor usability improvements

I didn’t know if Apple would approve an iPad-ready app if it did not support all orientations. So I implemented a mode for portrait orientations for iPad and retrofitted it for iPhone as well.

A big thank you goes to Erica Sadun who inspired me to take on these changes. When I met her on the Voices That Matter Conference in Seattle she played around with SpeakerClock as if it where the coolest of all toys, making me really proud of it. But I cringed seeing the iPhone-app on her iPad so I definitely had to make a HD-version. I dedicate this one to Erica.

I also added the information on how to start and stop the timer to the instructions. Some people did not understand that you can do so by simply tapping the screen.

Also this version marks the end of the “free trial” for SpeakerClock 1.0. As soon as it goes live I will raise the price. So if you want to get it for free, then better get it now. If you liked 1.0 then the new + button is your chance to show your appreciation, it will give you 5 instead of 1 preset. A preset saves the timer starting value, the yellow and the red threshold values.

Personally I use SpeakerClock whenever I’m recording YouTube videos. A couple of times I went over the maximum of 10 minutes and my handy timer prevents this for good. Here’s a demo of the old and new features.

SpeakerClock 1.1. has been submitted to Apple for approval.

UPDATE: … has been approved.

UPDATE 2: … has a nasty bug where it would crash on all iPhones with an OS Version less than 4.0. So I already submitted an 1.1.1 update.

UPDATE 3: The 1.1.1 hotfix is now available on the app store.

World Cup Pools App

In case you where wondering … I was busy with an app I did in cooperation with Andreas Heck of der.heckser. According to my time tracker I spent 87 hours on it to get it to version 1.0 and yesterday, after twoandahalf intense weeks we sent version 1.0 to Apple for approval.

Let me give you a VIP tour of the app, first showing off the prettiness and functionality of the app itself:

After that, the second part shows you how my Xcode project looks like and I’m explaining some of the hurdles we had to overcome. This is for you beginning developers out there, but I’m hoping – if you are a seasoned pro – you still might find it interesting.

For an app like this it is essential that you spread the work amongst several people if you want to be able to finish it in about two weeks. When I get asked by new customers I am always responding “I’m a programmer, not a designer”. That’s actually bending the truth. I could probably design a decent app if I wanted to. Although my personal method of designing apps is to: build it, try it, improve it, rinse and repeat. That’s the kind of approach which is hard to get paid for, especially if the typical customer is not willing to pay more than a thousand dollars a pop.

The second thing I generally try to avoid is server-side work. I have done a bit of VB.NET programming on my server and I could do most of the things I would need, but I just hate it. Cannot tell you why, I’m in love with objective-C and anything else feels wrong to me. And any app that is social or needs the cloud to work needs a server to run off of.

Often customers are not aware of these two factors, and the different skillsets necessary.

I was glad that Andreas Heck approached me for a partnership where I could do what I do best. And he did that with sufficient funds to get the project flying. I mention currency as one of the essential ingredients because generally funding is what makes or breaks an app. Sure, you can write apps in your spare time, but then they are ripening in months, not weeks. Not a chance getting it done before this year’s soccer world cup.

Also if you’re a full time iPhone developer like me, then two weeks of non-stop work mean that you have to make have of what you need to sustain yourself financially in that time. Otherwise you have to divide your attention between a project like this and a well paying one.

It’s as simple as that: there there are some areas where you are way better than others. Money buys you the difference in time. This project has again proven to me that great apps need a team, even if it’s just two people.

UPDATE: The regular version of the app was approved by Apple on June 2nd after requesting that we remove “FIFA” from the list of keywords. We used this as an opportunity to fix a couple of minor bugs and raise the version to 1.0.1:

  • FIXED: Potential crash after user creation
  • FIXED: Inconsistent use of … and > on tableview cells
  • FIXED: Invitations to Pools would show with a %20 instead of a space
  • FIXED: Issue with animation going straight to entering an e-mail
  • FIXED: Some too long German expressions

The pro version is still under review, but you get the same functionality if you purchase the normal version and then use In-App-Upgrade to Pro.

Available on the iPhone App Store

GeoCorder 1.0.5

Seems there is an ever-growing community about my little tool GeoCorder which I originally made to get GPS data for testing. It evolved into a light-weight utility many people use for geotagging DSLR photos.

A user informed me that I messed up with the 1.0.4 version of the free variant. Seems both versions got out of sync. The only difference should be that the regular version costs $1 and the free versions has a banner ad. So I went in and fixed a couple of things.

CHANGES

  • Fixed some memory leaks
  • Updated AdMob framework in free version
  • replaced a deprecated function
  • fixed the free/paid inconsistency

Now all the new features from 1.0.4 are also in the free version as it was intended.

UPDATE April 16th: I had to self-reject my binary because it appears that there was a bug in the ZIP routine. I also added an extra switch to not record events when you are not moving. I removed the 1 Meter setting for the distance Filter because it looks like CLLocationManager ignores that. This gets replaced by the switch.

UPDATE April 17th: Self-Rejected another time. User asked me to change the XML Version to 1.0 for compatibility.

SpeakerClock 1.0

I like to watch the TED Talks, it’s always something novel and instructive and makes me believe that the world is generally moving towards a brighter future led by a handful of rather bright fellows.

Now one thing these guys do extremely well is to give a TALK. Through experimentation it was found that at that length the speaker is forced to condense his message and be as clear as possible to get his point across. This constraint is enforced by the famous TED speaker LED clock. (It’s actually a countdown and not a clock, but people seem to prefer using the word “clock” over “countdown”)

This is a countdown at the edge of the stage which at a glance shows you what your remaining speaking time is. Also there is a traffic light of sorts. Shortly before the end of the time a green light switches to yellow to signal that you have to start wrapping up your message. Red means that it’s time for the closing remarks.

Obviously there are dedicated devices out there which aim to fill exactly the same need of visualizing a speakers time constraint. And of course there are a couple of iPhone apps providing this functionality. My second choice of the name of my app was taken by Talk Timer. Yet another is Speech Timer Free which provides the traffic light and the Premium version of it even allows for exporting of your speaking log.

I might continue to wish I were a great and inspirational speaker, but in the meantime one thing that I CAN do is make such a countdown clock for iPhone. I just had to do it, because the thought of the clock kept popping up in my head and kept distracting me from other projects.

My goal for SpeakerClock was this:

  • emulate the famous TED clock as closely as possible
  • use big red LED numbers (for which I had invented DTLEDNumberView)
  • allow for all customization and setting via touch gestures, all on the main screen
  • use the second page solely to showcase DTAboutViewController

Version 1 uses the maximum size possible of the digits that is available in landscape mode. Because of this you can see the digits from several meters away which is necessary if you want to position it so that you can move freely while giving your speech. To maximize the size of the clock I had to move minutes and seconds closer together and wrap the traffic lights underneath.

I made it a special point to finish the app within a single day and so I left out several things which I can put it if there is any interest in this app at all. The art of 1.0 is to concentrate on the required core features and leave some of your brilliant ideas for future versions. Here are some ideas still on my mental drawing board:

  • German localization (and other major languages) – language is not critical to understand usage of the clock all texts are on the instructions and about pages
  • Multiple Presets – might be an idea for a freemium upgrade
  • Recording of speaking logs, summing up your total speaking time, exporting, sharing …

I made a YouTube video to demonstrate the app:

I sent the app to Apple yesterday. SpeakerClock will be available on the app store initially for free to get user feedback.

UPDATE: 2 days after submission SpeakerClock is now available on the app store.

GeoCorder 1.0.4

It’s been almost a year since my last update to GeoCorder, which is a handy little tool to quickly record GPS tracks and mail them to yourself for viewing in Google Earth or geotagging photos. It’s a very simple tool which I wrote to get GPX tracks for my own testing. If you believe the reviewers it serves it’s purpose very well

Since then SDK 3.0 was released and with it the possibility of sending attachments in E-Mails. Before that time I had to resort to sending the files via my own web server, but with this update this is now no longer necessary. And lately some reviewers started to complain about this old mode so I finally found a day to sit down and polish it up, fulfilling all the reviewer’s requests.

Changes

  • NEW: Set a distance filter to conserve battery life
  • NEW: Export via E-Mail now uses InApp E-Mail (if available)
  • InApp E-Mail: optional compression of sent GPX files
  • InApp E-Mail: GPX file now named with timestamp
  • German localization
  • Minor UI tweaks

The update covers GeoCorder and GeoCorder [FREE] and has been submitted to Apple for approval.

UPDATE: 29 hours later the update(s) are through the review process. That’s new record for me.

MyAppSales 1.0.15 – "Holiday Fix"

The latest version of MyAppSales contains a fix for times when iTunes Connect is offline, but the ITTS reporting site is still running.

This way you still get your daily sales reports throughout the downtime for ITC which was announced to go from December 23rd until December 29th.

Another minor change is that review scraping no longer is requires for the app totals to be loaded because all reviews for all apps are scraped at the same time anyway. This is a minor startup speed benefit.

Merry Christmas and Happy Holidays!

UPDATE Dec 26th: Apple caught up on using the ITTS url for report downloading and shut this down as well, giving this message.

So, there now really IS no way to get to your daily reports anymore. We all have to wait until Dec 29th.
