The first version of Days Since Pro was released on Sep 18, 2016 in the Google Play Store as a replacement to the app's predecessor Days Since Lists, which was launched even earlier.
Days Since Lists was designed for Android 2.0 and was created with a very early way of creating android apps through an Eclipse plugin. Days Since Pro is a big improvement over its predecessor and added features from many user suggestions.
Users can enter any number of life events and the app simply tell you have many days since that event or how many days until the event. The app let the user organize in categories, and present the data in several formats.
Each entry is stored on your phone in a SQLite data file.
The app had over 10,000 users, had many 5 star reviews and was installed all over the world.
As of Nov 2024, my Google Play app store is closed.
I here provide the source code for Days Since Pro. This source code will compile with Android Studio, and you can create an APK file and install in your Android device.
