Verdict
The clearest difference is rating: Smaint at 4.0 against YMOBD's 2.9. Smaint also leads on in-app purchases (none vs 4) and update cadence (every 3 weeks vs every 5 weeks). YMOBD's advantage is ads (none vs shown) and review sentiment (34% vs 0%). On price and device support 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. YMOBD sells 4 one-off in-app purchases. Smaint asks for nothing beyond the download.
Smaint holds the better App Store score, 4.0 against 2.9. That said, the two scores are not equally well evidenced: YMOBD has 86 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Smaint's written reviews are positive against 34% of YMOBD's, so the app with the better star average is not the one people write more warmly about.
Smaint ships an update every 3 weeks, YMOBD every 5 weeks. The most recent releases landed on October 14, 2026 and October 13, 2026 respectively.
