Verdict
The clearest difference is rating: Jamzone at 4.8 against Keep Time's 4.0. Jamzone also leads on ratings volume (9K vs 1) and update cadence (monthly vs every 4 months). Keep Time's advantage is ads (none vs shown) and iOS requirement (13.0 vs 15.0). On price, review sentiment, in-app purchases and monetization model 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. Keep Time sells 1 one-off in-app purchase and Jamzone sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
Jamzone holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Jamzone has 9K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 90% of Keep Time's written reviews are positive against 83% of Jamzone's, so the app with the better star average is not the one people write more warmly about.
Keep Time ships an update every 4 months, Jamzone monthly. The most recent releases landed on October 6, 2026 and October 19, 2026 respectively.
