Verdict
The clearest difference is review sentiment: Boost Focus Timer at 100% against Joi's 46%. Boost Focus Timer also leads on device support (3 vs 1) and iOS requirement (14.0 vs 17.6). Joi's advantage is rating (4.4 vs 3.7) and ratings volume (192 vs 3). On price, update cadence, 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. Boost Focus Timer sells 4 in-app purchases, starting at $1.49 per month and Joi sells 6 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
Joi holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: Joi has 192 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of Boost Focus Timer's written reviews are positive against 46% of Joi's, so the app with the better star average is not the one people write more warmly about.
Boost Focus Timer ships an update every 2 weeks, Joi every 10 days. Both last shipped on October 30, 2026.
