A coffee grinder companion
Being a pretty big coffee nerd in my free time, I was excited to hear about the release of the Fellow Opus - a capable entry-level grinder meant for beginners at a very competitive price point. However, the adjustment mechanism for the grind size is fairly complicated and has led to people shying away from getting the grinder.
On a lazy Sunday, I decided to build a very simple app to help people intuitively understand the mechanism and dial in the perfect coffee. The app was received very well (see comments on the accompanying Reddit post), so much so that Fellow decided to send me a unit as a thank you gift for creating it.
