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. YMOBD sells 4 one-off in-app purchases. Tkeeper asks for nothing beyond the download.
YMOBD holds the better App Store score, 2.9 against 2.0. That said, the two scores are not equally well evidenced: YMOBD has 84 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 34% of YMOBD's written reviews are positive against 50% of Tkeeper's, so the app with the better star average is not the one people write more warmly about.
YMOBD ships an update every 5 weeks, Tkeeper every 3 weeks. The most recent releases landed on September 21, 2026 and September 12, 2026 respectively.
