Finally!! I have looked and looked for a ToDo list app that doesn't try to link to and invade my calendar, email, contacts, texts, photos, notifications and every other database I have. I just want a simple, easy to use list function with some internal sorting features. This is it. PLEASE don't ruin it by forcing your way into every other app I have! Have been using the ad supported version (and the ads are not intrusive) but am about to pay for the ad-free version.

I really like this app. It's easy to use and do most of what I need it to do. I just wish that I could make a task be repeated for more than a week. Like, to give me a reminder to change my fish tank filter (which I do once a month) or to wash my comforter (which I do every 2 weeks). Also, adding sub tasks would be really helpful too.

I like it in its simplicity, but doesn't work without internet access (off line.) Doesn't work in some stores. Should have off line editing with after the fact syncing.
