Read full description

OpenTodoList is a todo list and note taking application. Organize todo lists, notes and images in libraries, which can be stored either completely local on the device you are working on (and hence ensure no information leaks out to untrusted third parties) or use the built in synchronization features which allows you to synchronize your libraries across devices using your self-hosted NextCloud or ownCloud server, other WebDAV servers or Dropbox. In addition, a library is just a directory holding the items of your library as simple files - this allows you to use any kind of third party synchronization tool to sync your information.

Verdict

The call

The clearest difference is in-app purchases: OpenTodoList at none against Notesnook's 20. Notesnook's advantage is update cadence (every 8 days vs every 2 months) and ratings volume (688 vs 4). On price, rating, review sentiment and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Notesnook holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Notesnook has 688 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 83% of OpenTodoList's written reviews are positive against 79% of Notesnook's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

OpenTodoList ships an update every 2 months, Notesnook every 8 days. The most recent releases landed on October 17, 2026 and October 29, 2026 respectively.
