Hi there,
I'm Leon, a solo developer from Poland who loves coffee. I've created Cofi, an open-source coffee recipe/brew timer app for alternative brewing methods. It's available on Android and WearOS and features seamless synchronization between both versions.
With Cofi, you can store your favorite ways of brewing coffee, and thanks to the step system, you will always see what you need to do and what the next step is. This way, your cup of coffee will be perfect every time. And if it's not, it's easy to adjust the timings to make it better next time.
By default Cofi contains recipes for most popular alternative methods, but you can always change then or add entirely new ones to fit your needs.
Cofi is 100% free and contains no tracking whatsoever. To be honest, I created it because I was frustrated with the lack of equivalent apps without built-in tracking.
Since it's my hobby project, I use it to explore new Android APIs and features. As a result, it supports dynamic theming, Material You, themed icons, WearOS, tablet UI, app shortcuts, Picture-in-Picture, and more.
You may be wondering, "Why would anyone need it?" Well, let me explain. I'm not a morning person, and I struggle with remembering exact timings and values. Having Cofi allows me to offload this information and makes my mornings easier. I hope it can do the same for you too.
You can get Cofi from the Play Store, F-Droid, or GitHub
Keep in mind that to sync between WearOS and Android you need to install both apps from the same place (eg. both from the Play Store, or both as APK from Github)
Most of the FOSS is something that someone built for themselves and released for other just because. Try not to hold grudges if someone is annoyed that suddenly they get spammed with request that they don't wanna deal with.
