# Solebe vs Key

The clearest difference is rating: Key at 4.0 against Solebe's 2.6. Solebe's advantage is update cadence (every 3 weeks vs every 6 months) and review sentiment (24% vs 0%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Key holds the better App Store score, 4.0 against 2.6. Both are backed by a comparable volume of ratings — 22 and 5 respectively. Written reviews complicate that: 24% of Solebe's written reviews are positive against 0% of Key's, so the app with the better star average is not the one people write more warmly about.

Solebe ships an update every 3 weeks, Key every 6 months. The most recent releases landed on July 4, 2026 and June 5, 2026 respectively.
