AutoSync is an Android application developed by 43waves that allows users to enable sync only when charging, connected to WiFi, at certain intervals, or just manually. The app has gained popularity among Android users due to its ability to help save battery life by reducing data usage.

One of the standout features of this app is that it allows users to sync their data only when certain conditions are met, such as when the device is charging or connected to a WiFi network. Users can also set the app to sync data at specific intervals or manually. It is worth noting that some settings require a foreground service (a little sync icon in the notification bar) for them to work correctly.

AutoSync supports the following languages: Chinese, Deutsch, English, French, Japanese, Korean, Portuguese, Russian, and Spanish. The translations are driven by the community on a voluntary basis, and the app owes its success in part to the dedicated volunteers who have improved the translations. Special thanks to Kyan Lee for the Korean translation, Victor Neves for the Portuguese translation, and Carlos Nañez for the Spanish translation.

Overall, AutoSync is a useful app for Android users who want to save battery life and control their data usage. It is easy to use, and the ability to customize sync settings makes it a valuable addition to any device.
