We have introduced many nice task manager apps, but if you just want to focus on an important task every day, the todo app Do.one may be more suitable for you.
Do.one is a simple and practical todo app developed by Luke Freeman, and designed for iPhone and iPod touch. The iPhone app features gorgeous, minimalistic user interface. Just tapping the screen with your finger you can quickly add new task for the day, but note that the todo app just allows you to add a task for a day so you’d better add the most important event during the day. Moreover, tapping the date, a calendar will show you the status of your tasks, you can also freely select month and year for checking. Apart from that, the todo app also notifies you when you activate notification function.
Do.one with a size of 4.2 MB is compatible with iPhone (optimized for iPhone 5), iPod touch and iPad running iOS 6.0 or later. The iPhone app is free for a limited time at present. If you’re interested, jump to App Store for more details.
