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.
CoffeeRatio holds the better App Store score, 5.0 against 3.1. Both are backed by a comparable volume of ratings — 2 and 8 respectively. Written reviews complicate that: 0% of CoffeeRatio's written reviews are positive against 43% of CoffeeOS's, so the app with the better star average is not the one people write more warmly about.
CoffeeRatio ships an update every 15 months, CoffeeOS every 3 weeks. The most recent releases landed on October 24, 2026 and October 28, 2026 respectively.
