What its App Store listing shows

Checked on 4 November 2026: Simple: AI Weight Loss Coach, published by AM APPS LTD. Apple shows the download itself as free, with a rating of 4.7 from 411,132 ratings. What any paid plan inside it costs is shown on that listing and can change at any time, so read the price there rather than here — and nothing else about their app is stated on this page, because nothing else was checked.

FastSyncer is not affiliated with, endorsed by or connected to AM APPS LTD. Their app's name appears here only to say which app this page is about.
