# Feather vs DietSensor Fasting

The clearest difference is rating: DietSensor Fasting at 5.0 against Feather's 4.5. DietSensor Fasting also leads on ads (none vs shown) and review sentiment (50% vs 38%). Feather's advantage is update cadence (every 10 days vs every 3 months) and ratings volume (328 vs 5). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Feather sells 3 in-app purchases, starting at $15.99 per 3 months and DietSensor Fasting sells 9 in-app purchases, starting at $29.99 per 3 months. Whichever you choose, the download price is not the number that matters.

DietSensor Fasting holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Feather has 328 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 38% of Feather's written reviews are positive against 50% of DietSensor Fasting's.

Feather ships an update every 10 days, DietSensor Fasting every 3 months. The most recent releases landed on October 12, 2026 and October 7, 2026 respectively.
