# Forme Fasting Timer vs GoTall

The clearest difference is rating: Forme Fasting Timer at 5.0 against GoTall's 4.6. GoTall's advantage is ratings volume (6.8K vs 1) and review sentiment (22% vs 0%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Forme Fasting Timer sells 4 in-app purchases, starting at $19.99 per month and GoTall sells 15 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Forme Fasting Timer holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: GoTall has 6.8K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Forme Fasting Timer's written reviews are positive against 22% of GoTall's, so the app with the better star average is not the one people write more warmly about.

Forme Fasting Timer ships an update every 2 weeks, GoTall every 9 days. The most recent releases landed on September 11, 2026 and September 22, 2026 respectively.
