# Intermittent Fasting Tracker ™ vs FastSloth

The clearest difference is ads: FastSloth at none against Intermittent Fasting Tracker ™'s shown. FastSloth also leads on rating (5.0 vs 4.5) and update cadence (every 6 days vs every 3 weeks). Intermittent Fasting Tracker ™'s advantage is ratings volume (2.4K vs 5) and iOS requirement (16.6 vs 26.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Intermittent Fasting Tracker ™ sells 16 in-app purchases, starting at $2.99 per month and FastSloth sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

FastSloth holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Intermittent Fasting Tracker ™ has 2.4K ratings behind it against 5, so its average is the more settled of the two.

Intermittent Fasting Tracker ™ ships an update every 3 weeks, FastSloth every 6 days. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
