# OCO vs Particle Escape

The clearest difference is rating: OCO at 4.6 against Particle Escape's 3.8. OCO also leads on ratings volume (2.4K vs 12) and chart position (#165 vs unranked). Particle Escape's advantage is in-app purchases (none vs 8) and update cadence (every 4 days vs every 5 weeks). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. OCO sells 8 one-off in-app purchases. Particle Escape asks for nothing beyond the download.

OCO holds the better App Store score, 4.6 against 3.8. That said, the two scores are not equally well evidenced: OCO has 2.4K ratings behind it against 12, so its average is the more settled of the two. Written reviews point the same way: 73% of OCO's written reviews are positive against 63% of Particle Escape's.

OCO ships an update every 5 weeks, Particle Escape every 4 days. The most recent releases landed on September 23, 2026 and September 15, 2026 respectively.
