Ask HN: Please review my iPhone productivity app

Hi everyone, this is my first time submitting a project here, but I'm a daily HN lurker. Infact HN has been the inspiration for the app (scratch your own itch, work on a project in your spare time after work everyday etc.) and this is the result.

The app is called Do5, it's essentially a todo app with a twist. Unlike competing products, I often forget to open the app and read my todo list. My idea is to display the list as your wallpaper so every time you unlock your phone you'll be reminded of your todo list.

I have been working on the app at night after work for the last three/four weeks and my intention is to slowly improve the product over time.

I'd really appreciate your feedback. I have ten free promo codes to give out to HN readers (first come first serve!)
