Android Apps

Minimalistic Text

Minimalistic Text Logo

Minimalistic Text has started out as a simple proof of concept and - with the help of XDA developers - has grown quite big.
It has over 5 million downloads from the Google Play Store and even has been featured in the Play Store.
Today it has become a little bit old and outdated but there is still a core fanbase that uses it.

Paperlaunch Logo

Paperlaunch has been created to fill a gap I had in available apps.
I wanted to have a side launcher that activates when sliding in from the side but allows for immediate launch of an application (so not sliding in, lift finger, tap on app)
There has not been any app like that so I decided to create one.
At roughly the same time Google announced the Udacity Android development program. I was taking part and as this program required creating an app in the end I used Paperlaunch to finish that course.

While trying out different technology stacks that might be interesting for the UI development of home appliances I wanted to run .Net Core on our Linux based arm hardware.
This worked quite well but there is currently no real rendering framework for .Net Core.
As we already use Qt (with C++) I searched for a .Net binding to Qt that is able to integrate with QML.
The only project I found was Qml.Net (qml-net-core at that time) that was in an alpha stage and did not really work in our context.
So I jumped on board and brought Qml.Net, together with its author Paul Knopf, a big step forward. In the end it ran on our hardware and was feature complete for the features we would need.
Today it is already used by Paul in medical devices.
Sadly the amount of ROM that is needed is not low enough yet for the restrictions on our low-end range of hardware.

Remote Lego cars

Together with a friend of mine (Florian Wachs) we tweaked lego technic cars to be remote controllable via Bluetooth.
Basically to try the “physical web” how Google called it. Having the Bluetooth enabled device sending a beacon that the Android device then receives. This beacon transports a URL and that URL provides a SPA that uses WebBluetooth to control the car.

It turned quite a bit into an electronics project and involved Web development, Android Development and Embedded Development.

Sniffthat Logo

Sniffthat was the first “app” I ever created. Those programs weren’t called “apps” at that time.
It was also my first Open Source project.
It has been an active Wifi sniffer for Windows CE devices written int C# (using the .NET compact framework).
It was hosted on Codeplex. There is still an archived version around.
