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.
Odmaster holds the better App Store score, 3.8 against 2.8. That said, the two scores are not equally well evidenced: Odmaster has 1.1K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 50% of BJ's written reviews are positive against 29% of Odmaster's, so the app with the better star average is not the one people write more warmly about.
BJ ships an update every 5 weeks, Odmaster every 3 weeks. The most recent releases landed on October 2, 2026 and October 18, 2026 respectively.
