Verdict
The clearest difference is in-app purchases: Sonora at none against Tromme's 3. Sonora also leads on review sentiment (100% vs 80%) and iOS requirement (17.6 vs 27.0). Tromme's advantage is rating (4.6 vs 4.1) and update cadence (every 2 days vs every 2 weeks). On price, ratings volume, ads and device support 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. Tromme sells 3 in-app purchases, starting at $0.99 per month. Sonora asks for nothing beyond the download.
Tromme holds the better App Store score, 4.6 against 4.1. Both are backed by a comparable volume of ratings — 7 and 8 respectively. Written reviews complicate that: 100% of Sonora's written reviews are positive against 80% of Tromme's, so the app with the better star average is not the one people write more warmly about.
Sonora ships an update every 2 weeks, Tromme every 2 days. The most recent releases landed on October 22, 2026 and October 29, 2026 respectively.
