What its App Store listing shows

Checked on 4 November 2026: DoFasting Intermittent Fasting, published by FASTING SOLUTIONS UAB. Apple shows the download itself as free, with a rating of 3.9 from 4,813 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 FASTING SOLUTIONS UAB. Their app's name appears here only to say which app this page is about.
