# Fumis vs SolarGo

The clearest difference is update cadence: SolarGo at fortnightly against Fumis's every 5 months. SolarGo also leads on ratings volume (7 vs 2). Fumis's advantage is rating (3.5 vs 3.3) and iOS requirement (12.0 vs 15.0). 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 3.3. Both are backed by a comparable volume of ratings — 2 and 7 respectively. Written reviews complicate that: 8% of Fumis's written reviews are positive against 10% of SolarGo'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, SolarGo fortnightly. The most recent releases landed on October 5, 2026 and October 13, 2026 respectively.
