Literally can't wait to return to Berlin this year. Thrilled to once again be on stage at droidcon, this time talking about... 🥁 ... wake locks. Don't believe that's still a thing in 2026? By all means. Join me and let me explain 😎 #nextapp26

Speaker card: Thomas Künneth. Waking up safely: Reducing background wake locks with Android 17. #nextapp26 Oct 7-9 Berlin

TKWeek, my versatile #Android #OpenSource date and calendaring tool, is now also available via #Obtainium. Check it out at tkweek.tkuenneth.dev and get the app through Obtainium or F-Droid. And, no, it is not available on Google Play anymore. It hasn't for quite a while. Why? Sensitive permissions

Moni and I just returned from an absolutely gorgeous escape from the summer heat. We've been at the North Sea (Zandvoort, The Netherlands). Yes, we deliberately avoided the Grand Prix 🏎️ 🏁. 🔋 perfectly recharged, looking forward to do some coding now.

Possibly the least useful, insanely cool app I shipped: Strange Piano. One octave. The "music" is haptic. Source on Codeberg (EUPL) — small modern Android codebase for a talk called 5 things you didn't know about vibrators. codeberg.org/tkuenneth/strangepiano Play Store link in the comments

Finishing a presentation or talk in time can be challenging. Min Time is here to help. Truly open source, native Android, slick Material 3 Expressive. Get it now on Google Play or F-Droid. mintime.tkuenneth.dev

Happy Sunday. Having fun polishing Min Time. Mind you, the app started 2014, and this is not Jetpack Compose. Remember, legacy does not mean shitty, it however does require expertise

MarvinCopy 1.2 changes its initial window size so that it fits 4 album columns without extra empty space. And albums with .m4v files now show a cover from the video when no embedded artwork is found codeberg.org/tkuenneth/ma...

Happy weekend. Be nice has a very handy hyper-scroll feature. If you did not give it a try, you really should. This is how modern #Android launchers should look like #OpenSource codeberg.org/tkuenneth/be...

Always a pleasure to return to Berlin. This week it's a business trip, but next week it'll be I/O Connect ❤️🔥

That's me at the underground station Friedrichstraße in Berlin

Just in case you were wondering why I was a little quiet the last two weeks. That's because Moni and I had an incredible vacation in York. Absolutely fabulous place

Fancy local content over cloud streaming but have no idea how to easily sync from macOS to your Android device? MarvinSync just requires ADB and an USB connection or wireless debugging being set up codeberg.org/tkuenneth/ma...

Be nice has a transparent app window so that the system wallpaper can shine through. Unless on #ChromeOS, that is, because there Android app window background is quite a mess. Therefore, Be nice 2.1.2 can now show custom backgrounds

I continued working on the dock. You can now also add folders. And unlike Google's launcher, Be nice allows you to have a custom folder emoji

Happy weekend. Be nice continues to receive awesome features. This will land soon: adding an app pair to the dock ❤️ #Android #Launcher #JetpackCompose

We have a public holiday today, here in Germany, so enjoying a very relaxed morning. #NowSpinning Fallen Angel by Uriah Heep. While I love and appreciate that bands want (have to) evolve, still get more excited about the earlier progressive pieces. That's not to say, though, this isn't great music ❤️

Two new features for Be nice. Arrange favorites by simply dragging and dropping them (including niiiice haptic feedback), and a slick open source licenses view. Kudos to @mikepenz.dev and @calvin.sh #AndroidDev #JetpackCompose codeberg.org/tkuenneth/be...

Today updated TKBirthdayReminder to target #Android 17. The floating apps feature (Bubbles) is pretty nice. Since my apps are good citizens across form factors anyway, no changes needed. Curious to see if Play Store reviews complain about READ_CONTACTS. Well, it's a birthday reminder, after all 🤪

Hey @developers.google.com @androiddevs.bsky.social Did you know that my #OpenSource #Android launcher Be nice allows the creation of app pairs beyond foldables? Honestly, I don't know a cooler way to use split-screen on any Android device supporting split-screen play.google.com/store/apps/d...

Thomas Künneth @tkuenneth.dev · 07/05/2026

Curious to see a slick, fast, modern, lean #OpenSource #Android launcher written entirely in #Kotlin and #JetpackCompose that works great across form factors and device categories? play.google.com/store/apps/d...
