Dear all,

after being inactive for quite some time I decided that it is time to let go.

I was approached by the people from, which kindly provided me the data for RegenRadar, asking me if they could take over the future development of RegenRadar. Since I stopped working on IPhone applications some time ago and I do not have the time to keep the app running, I decided to let them continue the work. I hope they will keep RegenRadar the nice and easy to use tool it was designed to be.

For any further inquiries please contact wetteronline directly.

All the best, m

427 vs 472

Tuesday, February 8th, 2011

My recent attempt to fix a problem with Regenradar not displaying the correct location failed ;) The problem occured due to a size change of the radar images provided by wetteronline. The displayed position is calculated from the longitude and latidue provided by the iphone GPS combined with the known longitude and latitude of two cities (Hamburg und Munich) and their position on the image (in pixels). When the size of the image changed, this pixel position of the cities needed to be udpated. While reading off the new positions from the image I introduced a typo, putting down 427px for Munich where it should have been 472px. So, while when being in Hamburg the position was correct, the further away the worse the position got.

tl;dr – new fixed version is on the way (1.3.6). I will test it today and will send it to Apple for review tomorrow.

[UPDATE] Update has been submitted to Apple, now we have to wait …

[UPDATE] Update is now available in the App Store. Please let me know about your experience (e.g. is the positioning now working as expected)

one fixed, two new

The old programming rule still holds: you fix one bug and create two new ones. I (not so much proudly) present: ZugInfo 2.1.4 – fixing:

  • A bug introduced in ZugInfo 2.1.3, which wrongly grouped S-Bahn under the RE/RB button
  • Improved nearby services
  • Fixing a typo in the German disclaimer text

To avoid another quick fix, this time I will apply more rigorous test scenarios, so it might take a few more days before I will submit this version. Sorry for the inconvenience and a happy new year to all of you!

[Update:] Just submitted the new version. Let’s hope for the best, and that I have not introduce more bugs ;)

and .. again

yep, increasing the prices goes hand in hand with changing the mobile website. Today the DB decided to again change their webinterface (which is browsed by ZugInfo). This means for the moment ZugInfo is broken and we are working on a fix. Sorry for the inconvenience.

[Update:] Alrighty then! Bugfix version finished, just needs some polishing (i.e. testing). Hope to submit it tomorrow. If I find the time over Christmas, I will try to implement a more sustainable solution for the website change problem.

[Updated:] Just submitted the bugfix to Apple (ZugInfo 2.1.2, Dec 13, 10pm). Keep you posted.

[Update:] Thanks to the swift work of the guys and girls of the Apple App review team ZugInfo 2.1.2 is now available in the App Store (Dec 18).

the end?

Today Deutsche Bahn (German Railways) announced that they will publish their own IPhone appliciation. The detail – including the release date – are still vague, but if it is any good, I might stop developing ZugInfo. I keep you guys posted. And let me know what you think.

[Update:] There we go, DB Navigator is available in the App Store (Dec 15). Let’s have a look.

oops .. they did it again

Thursday, October 1st, 2009

Today the DB website changed and caused some problems with the ZugInfo display of the connection type (thx to Markus for pointing that out). I am working on an update…..

[Update:] I got a working version of a quick fix on my laptop. A few more test and I will submit it to the App Store.

[Update:] A quick fix version has been submitted to the App Store. If anyone knows how to speed up the Apple review process, please contact me. Thank you for your patience.

[Update:] Thanks to the Apple review team the update is now available at the App Store (Oct. 3rd).
