Google Timeline Visualizer

Google keeps a Timeline of where you have been, and this turns that export into an animated travel video. Point it at the Timeline.json you exported from Android settings or Google Maps, pick a month range or exact dates, choose how the camera moves, then preview the journey and render an MP4 to keep or share. There are two ways in: the Android app needs 8.0 or newer and is installed from the repository's releases rather than Google Play, since it is not listed there yet. On iPhone the same thing runs as a web app in Safari 16.4 or newer, and the Timeline file never leaves the device. The code is Kotlin under an MIT license, with the readme also written in Korean and Japanese.
