# AOJ+ vs Roll Time

The clearest difference is monetization model: Roll Time at free against AOJ+'s free with in-app purchases. Roll Time also leads on update cadence (weekly vs every 5 weeks) and review sentiment (100% vs 88%). AOJ+'s advantage is ratings volume (395 vs 25) and device support (4 vs 2). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. AOJ+ sells 14 in-app purchases, starting at $24.99 per month and Roll Time sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for AOJ+ against 5.0 for Roll Time. That said, the two scores are not equally well evidenced: AOJ+ has 395 ratings behind it against 25, so its average is the more settled of the two. Written reviews are what separate them: 88% of AOJ+'s written reviews are positive against 100% of Roll Time's.

AOJ+ ships an update every 5 weeks, Roll Time weekly. The most recent releases landed on September 24, 2026 and September 21, 2026 respectively.
