Update, 28 October: the app is in internal testing and is not available on Google Play yet. Google’s policy for new developer accounts means it can be published after the test period, in about two weeks (around mid-November 2026). Many apps on Google Play have names similar to OpenTodo, and none of them is this one: until the listing is public, anything you find by searching the store is someone else’s app. Once it is public, this site will link to it.
OpenTodo has had an Android app since 0.10. Until now you installed it by downloading it from the release page on GitHub, which works, but asks people to trust a file from the internet and to remember to update it by hand. This week I sent it to Google Play, and that brings me to the reason for this post: I need your help for the last step.
Why twelve people
Google asks every new developer account to run a closed test before an app can go public: at least twelve testers who keep the app installed for fourteen days in a row. It is a reasonable rule. It also means a small open-source project cannot publish on its own, however finished the app is.
What the app does
The Android app opens your own OpenTodo server, like the installed web app, and adds what only a phone app can do: reminders that arrive on time without a push service, sharing files from other apps into a task, home-screen widgets and fingerprint unlock. It needs Android 8.0 or later. It talks to your server and to nothing else: no analytics, no ads.
How to join
- Send me the email address of the Google account on your Android phone, by email to [email protected] (subject “Android tester”) or as a direct message on Discord. Please don’t post it in a public comment. I add it to the test list and use it for nothing else.
- Once Google has approved the test release, I send you a link. Open it on your phone, tap Become a tester and install OpenTodo from the Play Store.
- Keep the app installed for fourteen days. That is the part that counts for Google; use it as much or as little as you like.
You need an OpenTodo server to connect to. If you don’t run one yet, enter demo.open-todo.app on the first screen: the public demo gives you a private sandbox with sample tasks, no account needed.
What I would like to hear
Anything that surprises you. A reminder that arrived late, a screen that looks wrong on your phone, a gesture you expected and didn’t find. Tell me on GitHub, in an issue or in the discussion about the test, or by email. Every report from this test goes into the next releases.
Thank you. Twelve people is not many, and it is the difference between “download this file” and “install it from the Play Store”.
