Hello, I am Friedemann. I ❤️ 📷, 🚲 &
<code/>. And I am the developer of Tacho.
In the summer of 2013 I bought a new bike, a Brompton in Raw Laquer with 2-speed gear and Schwalbe Kojak slicks.
Of course, I needed a speedometer for my new racing Brompton. Since nothing could convince me in the App Store, I made my own bicycle computer. Speed, total distance and time my first iPhone app displayed. I had the app in use for more than five years and more than 7000 kilometers and was quite satisfied. Only a temperature gauge I have occasionally missed.
At the beginning of this year, during the spring cleaning of my bike, it has seized me again. I finally wanted to implement the temperature gauge and had an idea how to visualize wind information.
I was tired of the old Objective-C code. So I developed a completely new app with React Native. But I was not really happy with the result. The compass animation ran with 60 fps, but did not feel buttery soft and the power consumption was too high.
I could not help getting into Swift and porting the app. But the effort was worth it. The animations run buttery soft, need little energy and the bundle size has shrunk from more than 40 MB to 1.5 MB. 🚀
With the new app, I have now gone the last mile and finalized it for the App Store. Since May you can 🎉 download Tacho for free on the App Store 🎉. It is translated to English, German, French, Spanish, Korean and Arabic and available for iPhone and iPad.
