android-keyboard
Official FUTO Keyboard Issue Tracker and Source Mirror of https://gitlab.futo.org/keyboard/latinime
Project mention: I burned all my tokens researching how to save tokens | news.ycombinator.com | 2026-07-19I've shipped small, simple, unambitious internal things for our company that saved people lots of time, and I've shipped them in minutes rather than the a day or two they used to take.
I've just shipped a migration from our old auth service to the new one in a week, a migration that we've put off for three years because it would take the team months to finish.
I've shipped small side-projects that I'm the primary (and usually only) user of, but they now take me two days rather than weeks of effort and learning (e.g. https://www.writelucid.cc, https://pine.town, https://stavrobot.stavros.io, https://github.com/skorokithakis/dracula).
I've made changes in OSS apps that I just wouldn't have made otherwise (https://github.com/futo-org/android-keyboard/pulls/skorokith...), and even some closed-source ones (https://www.stavros.io/posts/adding-a-feature-to-a-closed-so...).
I've shipped hardware projects that would have taken me months of learning in a few days (https://www.stavros.io/posts/i-made-a-voice-note-taker/).
How's that?

CoMaps
A mirror of https://codeberg.org/comaps/comaps. CoMaps is a community fork of Organic Maps. Based on principles of openness & transparency, not-for-profit & in the public interest, community-driven & accountable, fully free and open source software!
Project mention: Make Your First Edit to OpenStreetMap in the Next 15 Minutes | news.ycombinator.com | 2026-09-12I've read through these comments, and one useful app that has not been mentioned is Vespucci: https://vespucci.io/
It's not got the best UX, but it does let me edit anything from my phone. This means that I can easily check and/or edit the tags for a path or a track. For example, recently I was on a track that had steps. These weren't on OSM, but I could modify the track on Vespucci to add them. Easier to do on my laptop, but I'd forget to do them by the time I got home.
The other OSM apps, I can recommend but have been mentioned are CoMaps (https://www.comaps.app/) for viewing and route finding and Street Complete for easily updating data. Street Complete (https://streetcomplete.app/) has got a bit more powerful recently as you can now add things like toilets, bins, and benches
