# OCO vs Rainmaker

The clearest difference is rating: OCO at 4.6 against Rainmaker's 3.9. OCO also leads on ratings volume (2.4K vs 36). Rainmaker's advantage is ads (none vs shown) and iOS requirement (10.0 vs 15.0). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. OCO sells 8 one-off in-app purchases and Rainmaker sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

OCO holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: OCO has 2.4K ratings behind it against 36, so its average is the more settled of the two. Written reviews split almost evenly too, at 73% and 73% positive.

OCO ships an update every 5 weeks, Rainmaker every 2 months. The most recent releases landed on October 15, 2026 and October 9, 2026 respectively.
