# OverRapid vs O2Jam

The clearest difference is rating: O2Jam at 5.0 against OverRapid's 4.2. O2Jam also leads on update cadence (every 2 weeks vs every 2 months). OverRapid's advantage is ads (none vs shown) and ratings volume (79 vs 1). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. OverRapid sells 23 in-app purchases, starting at $3.99 per month and O2Jam sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

O2Jam holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: OverRapid has 79 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 65% of OverRapid's written reviews are positive against 71% of O2Jam's.

OverRapid ships an update every 2 months, O2Jam every 2 weeks. The most recent releases landed on October 20, 2026 and October 5, 2026 respectively.
