tudo

To-do lists are supposed to be easy, yet everyone seems to be making them complicated.
You just want to write down a simple shopping list but then find yourself dealing with user accounts, permissions, roles, ads, autocompleters, AI helpers, location-based services, user tracking, etc.

tudo is an experiment on simple, private, yet synchronized to-do lists.

Anonymous
No user accounts, registrations 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 appear immediately in every connected device where the app is open and online.

Offline-first
Any changes made to the list are stored locally on the device and synchronized when network is available.

Private
Each list is identified by a large random unique string that should make it effectively impossible to guess.

Forgetful
Lists exist on the server for relatively short timespans, just enough to perform synchronization between active devices.

Open-source
Look at how it's built. Modify it. Host your own server. Maybe help me improve it?

Multi-platform
Available on Android and iOS.
