Verdict
The clearest difference is rating: Fumis at 3.5 against WatchPower's 2.5. WatchPower's advantage is ratings volume (73 vs 2) and review sentiment (17% vs 8%). On price, update cadence, ads and in-app purchases 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. Neither carries in-app purchases, so what you see is what you pay.
Fumis holds the better App Store score, 3.5 against 2.5. That said, the two scores are not equally well evidenced: WatchPower has 73 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 8% of Fumis's written reviews are positive against 17% of WatchPower's, so the app with the better star average is not the one people write more warmly about.
Fumis ships an update every 5 months, WatchPower every 3 months. The most recent releases landed on June 11, 2026 and August 31, 2026 respectively.
