We have introduced many powerful task managers, but if you just need a simple and useful todo app to remember those things you want to do, the Thinglist may be a nice option.
Thinglist is simple, practical todo list app designed for iPhone. The iPhone app sports a simple user interface along with 9 well-designed icons that present 9 different tasks, including bar, book, food, idea, movie, music, person, place and product. Just tapping an icon you can easily create a todo item with a title and detailed description, and swiping left or right on every item with your finger, you can remove your todo or share it via Email, message or other social media. Apart from that, filter feature lets you easily find out specific todos with ease.
Thinglist is available for free at present. If you need it, head to App Store for download.
