I'm proud to say that switching from Appigo Todo to your app was a good decision. One of the biggest reasons for my switching is your export and backup feature without the need for sync. The Toodledo free account does not support subtasks. This simplifies life for people who want a remote backup copy and yet do not intend to sync with an external service.
Almost every conceivable flow was handled. Using your app is truly a great experience. Some minor suggestions though:
1. When holding over a note for several seconds - you launch a menu. Can you change the "DONE" to "MOVE" instead? It's more useful. You don't really need a done button there anymore since you have it in the main screen.
2. There may be some major problem in handling new notes. I don't seem to get where they are supposed to go by default. Sometimes they go to one folder, sometimes to another. Can you have some setting where the default behavior of new notes can be customized?
3. I thought dynamic calendars should be like smart playlists in itunes. Looks like it works with tags but not with normal text search.
4. There's this folder called Toodledo that was created when I first downloaded my notes. Now that folder can't be deleted.
Please have time to check the above concerns. Your app is really great. Seriously. You deserve all the awards. More power.
