Obtainium is an Android app that lets you install and update other Android apps directly from their original source, such as their GitHub releases page, GitLab, F-Droid, or other app stores, without going through the Google Play Store. It monitors those sources and notifies you when a new version is available, then lets you install the update in one tap. The problem it solves is app freshness and trust. When developers release new versions of open-source Android apps, those updates often reach the Play Store slowly or not at all. Obtainium bypasses that delay by going straight to wherever the developer actually publishes the APK file (an APK is the Android app installation package). You are always getting the version the developer intended, directly from their release infrastructure. Supported sources include GitHub, GitLab, Forgejo/Codeberg, F-Droid and third-party F-Droid repositories, SourceHut, APKPure, Aptoide, Uptodown, Huawei AppGallery, and a number of other app stores. If none of those match, you can also point it at any webpage that contains direct APK download links. To help users get started, there is a crowdsourced database of pre-configured app sources at apps.obtainium.imranr.dev, so you do not have to figure out each app's release URL yourself. Obtainium is built in Dart (the language used for Flutter mobile apps) and is itself available on F-Droid and IzzyOnDroid. It is intended for users who want more control over their app updates, particularly those using open-source apps.
