TimeStats is an all-in-one app that seems to have it all: scheduling, calendars, Kanban boards and basic project management. But its most interesting feature is the built-in Pomodoro timer.
The Pomodoro Technique is a simple productivity method that has you working in 25-minute bursts, followed by five-minute breaks. This app will basically serve as your timer and remind you when it's time to take a break.
TimeStats also helps you break down projects in smaller tasks. The project management tool is broken down into three parts -- Context, Project and Task. Context is the group of projects, Project is the group of tasks, and the Task is a single action.
When you're ready to get started, choose a task and start the timer. Eventually, you'll learn how much time certain tasks require, and how long a full project will take to complete. TimeStats will also provide you with a detailed report of how you're time is spent.
TImeStats is available on Windows Phone and Android for $2.99. A free version is also available.
