Wasiat is an Android app developed by Yayasan Komunikasi Bersama that provides daily devotionals for individuals and families. The app is free to download and can be used offline. With its user-friendly interface, the app allows users to swipe left or right to read devotionals from previous or future days. Users can also quickly return to the current day's devotional.

One of the app's standout features is the ability to set an alarm to remind users to read the daily devotional. Additionally, users can easily share the devotional with friends and family. The app also includes a feature that allows users to click on Bible verses to read them and listen to an audio/radio version by clicking the play button.
