Verdict
The clearest difference is rating: Savi at 3.0 against YBOOK's 1.0. Savi also leads on update cadence (every 3 weeks vs every 6 weeks). YBOOK's advantage is review sentiment (16% vs 0%) and iOS requirement (6.0 vs 13.4). On price, ratings volume, ads and in-app purchases 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. Neither carries in-app purchases, so what you see is what you pay.
Savi holds the better App Store score, 3.0 against 1.0. Both are backed by a comparable volume of ratings — 3 and 2 respectively. Written reviews complicate that: 16% of YBOOK's written reviews are positive against 0% of Savi's, so the app with the better star average is not the one people write more warmly about.
YBOOK ships an update every 6 weeks, Savi every 3 weeks. The most recent releases landed on October 17, 2026 and October 9, 2026 respectively.
