CalStamp is a simple app that lets you log everyday routines into your phone's own calendar with a single tap.

Create a "button" for each routine you want to track (set a title, color, icon, and duration) 2. Tap the button on the main screen 3. It's instantly recorded as an event in your device calendar Viewing, editing, or deleting records happens in your regular calendar app. CalStamp is purely for logging, so there's nothing extra to figure out.
