Productivity Sauce

Need a helping hand to develop good habits and get rid of bad ones? Try the Did I app for Android. It is a simple tool that lets you record whether you performed a specific action or not. For example, if you start a language course or 365 photography project, use the app to create Did I practice language? and Did I photograph? entries. You can then use the Yes and No buttons to track your progress, and the dedicated Progress screen provides a visual overview of your performance.

Did I is released under the MIT license, and its source code is available in the project's GitHub repository. You can also install Did I from the F-Droid store. The app hasn't been updated for a while, but it still does the trick.
