# Ref Tools vs Termostato TermoGea

The clearest difference is rating: Ref Tools at 3.9 against Termostato TermoGea's 1.0. Ref Tools also leads on ratings volume (52 vs 1). Termostato TermoGea's advantage is review sentiment (67% vs 58%) and iOS requirement (12.0 vs 15.0). On price, update cadence, 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.

Ref Tools holds the better App Store score, 3.9 against 1.0. That said, the two scores are not equally well evidenced: Ref Tools has 52 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 58% of Ref Tools's written reviews are positive against 67% of Termostato TermoGea's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on October 24, 2026 and October 18, 2026 respectively.
