Verdict
The clearest difference is review sentiment: AOJ+ at 88% against G13BJJ's 44%. AOJ+ also leads on rating (4.9 vs 4.3) and ratings volume (404 vs 7). On price, update cadence, ads and in-app purchases 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. G13BJJ sells 1 in-app purchase, starting at $9.99 per month and AOJ+ sells 10 in-app purchases, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.
AOJ+ holds the better App Store score, 4.9 against 4.3. That said, the two scores are not equally well evidenced: AOJ+ has 404 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 44% of G13BJJ's written reviews are positive against 88% of AOJ+'s.
Both ship on a similar rhythm, roughly every 5 weeks. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
