# IF vs Forme Fasting Timer

The clearest difference is review sentiment: IF at 61% against Forme Fasting Timer's 0%. IF also leads on ratings volume (2.7K vs 1) and device support (4 vs 2). Forme Fasting Timer's advantage is rating (5.0 vs 4.8). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. IF sells 14 in-app purchases, starting at $9.99 per month and Forme Fasting Timer sells 4 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

Forme Fasting Timer holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: IF has 2.7K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 61% of IF's written reviews are positive against 0% of Forme Fasting Timer's, so the app with the better star average is not the one people write more warmly about.

IF ships an update every 3 weeks, Forme Fasting Timer every 2 weeks. The most recent releases landed on September 25, 2026 and September 11, 2026 respectively.
