FlashbackPrism is an open source PhotoPrism client that presents photos from your library taken today in previous years. The application also notifies daily about memories from your library by presenting a notification in the morning.
The application supports Linux, MacOS, Windows, Android and iOS. Only on Android, however, the app notifies daily when the app is not running. I only provide binaries for Android arm64 here. For different builds, you'll have to build from the sources.
