tudo lists app for iPhone and iPad

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 its built. Modify it. Host it yourself. Maybe help me improve it?
