Verdict
The clearest difference is ads: GBDev at none against OhMyBoy's shown. GBDev also leads on update cadence (every 4 days vs every 6 weeks) and monetization model (free vs free with in-app purchases). On price, in-app purchases, device support and iOS requirement 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. OhMyBoy sells 3 in-app purchases, starting at $2.99 per 7 days and GBDev sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
GBDev holds the better App Store score, 3.3 against 3.0. That said, the two scores are not equally well evidenced: GBDev has 19 ratings behind it against 2, so its average is the more settled of the two.
OhMyBoy ships an update every 6 weeks, GBDev every 4 days. The most recent releases landed on October 8, 2026 and October 24, 2026 respectively.
