# Sono vs Stack

The clearest difference is ads: Stack at none against Sono's shown. Stack also leads on monetization model (free vs free with in-app purchases) and review sentiment (100% vs 89%). Sono's advantage is rating (4.7 vs 4.3) and update cadence (every 3 weeks vs every 6 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Sono sells 11 in-app purchases, starting at $3.99 per month and Stack sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Sono holds the better App Store score, 4.7 against 4.3. Both are backed by a comparable volume of ratings — 23 and 6 respectively. Written reviews complicate that: 89% of Sono's written reviews are positive against 100% of Stack's, so the app with the better star average is not the one people write more warmly about.

Sono ships an update every 3 weeks, Stack every 6 weeks. Both last shipped on October 15, 2026.
