Verdict
The clearest difference is ratings volume: Nomu at 97 against FastSloth's 5. Nomu also leads on device support (4 vs 2) and iOS requirement (15.0 vs 26.0). On price, rating, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Nomu sells 5 in-app purchases, starting at $2.99 per 7 days 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 4.8. That said, the two scores are not equally well evidenced: Nomu has 97 ratings behind it against 5, so its average is the more settled of the two.
Nomu ships an update every 5 days, FastSloth weekly. Both last shipped on November 5, 2026.
