Free access to substitution plans – Deobfuscation adventures
29.12.2019 , WikiPaka WG: Esszimmer

Many schools in Germany choose to distribute their substitute plans via a proprietary platform. The provided client software is not very pleasurable to use and inconveniences users with its dependency on Google Play Services. That's why I develop a free client for Android called DSBDirect, which is able to display plans in a nice, filtered way.

That's why I develop a free client for Android called DSBDirect, which is able to display plans in a nice, filtered way. Since they noticed my app, the company operating DSB has been obfuscating their various endpoints more and more in an attempt to prevent my app from working, while on the other hand not being very competent at security. It's a cat-and-mouse game.

I'm a student in the eleventh grade of a Gymnasium in Schweinfurt, Germany. I'm enthusiastic about free software and sometimes develop this Android app, even though I stopped using Android in day-to-day life.
