tudo is an experiment on simple, private, yet synchronized to-do lists. Anonymous No mandatory user accounts or tracking of any sort. Shareable Lists can be shared between your devices or trusted contacts simply using the list id. Real-time Changes to lists propagate immediately to every connected device where the app is open and online. Private Each to-do list has a random unique identifier that is effectively impossible to guess. Offline-first No loading screens. The app stores all the data it needs locally and works perfectly without a connection. Open-source Look at how it's built. Modify it. Host it yourself. Maybe help me improve it?
