Pomo

Pomo is a pomodoro timer that helps you stay focused and improve your productivity. The app is based on the Pomodoro Technique™ that protect you from distractions by laying out your work into short time intervals called “pomodoros” (one pomodoro lasts by default 25 minutes). After each pomodoro you take a short break (5 minutes) and after 4th one you take a long break (15 minutes).

Key featues:

• saves records of accomplished tasks (task, completed and abandoned pomodoros, total time)
• multitasking support
• continues in countdown even if it's interrupted by a call or by pushing the Home button (even on older iPhones!)
• local notifications support (iOS4 only) - notification will let you know when time is up even if the app itself isn't launched
• Retina display ready
• fully customizable
