Edits by Instagram
iPhone / iPad·VideoEdits is Instagram's video creation app for phones: the App Store lists it for iPhone, the official site links to Google Play for Android, and you log in with an existing Instagram account. The official pages describe a timeline with clip-level precision, automatic captions, green screen, effects, templates and exports with no watermark. The App Store lists the app as free with in-app purchases that it does not itemize.
