# Fumis vs Aqua Temp

The clearest difference is rating: Fumis at 3.5 against Aqua Temp's 1.9. Fumis also leads on iOS requirement (12.0 vs 15.0). Aqua Temp's advantage is update cadence (monthly vs every 5 months) and ratings volume (10 vs 2). On price, review sentiment, ads and in-app purchases there is nothing between them.

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 1.9. That said, the two scores are not equally well evidenced: Aqua Temp has 10 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 15% of Aqua Temp'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, Aqua Temp monthly. The most recent releases landed on June 11, 2026 and September 19, 2026 respectively.
