I use this for to-do lists, shopping lists, projects, pretty much everything. You can import from just about any other software, and the interface is fantastic. Nested trees, the best drag/drop implementation I've come across on Android period. If you used Treepad you'll feel right at home. One minor thing I wish it had was the capability to backup/restore to Google Drive. If you get the Pro version, you can backup/restore to the internal storage, which is good, and I use it a lot.

Absolutely spectacular app. Easy to use. So many helpful features and just does everything you could ever want when needing to make, edit, and export outlines. I just had a problem where another app restricted Outliner's Internet access causing problems. The developer responded immediately with very knowledgeable and helpful ideas to help me find and solve the problem. This is an extremely high quality app that I've been using extensively for a year. It is so well worth the purchase!! 🙏

It's very straight forward and easy to use. The due date function is convenient. However, I wish you could add the time for when something is due. I like the checkmark feature for when you are done and the addition of notes for the activity. I would have like a reminder for each activity that had a due date but for a basic checklist it's pretty good.
