# ONO vs Code Burst

The clearest difference is in-app purchases: Code Burst at none against ONO's 1. Code Burst also leads on ads (none vs shown) and update cadence (every 9 days vs every 2 months). ONO's advantage is ratings volume (9 vs 1) and device support (3 vs 1). On price and rating there is nothing between them.

Both are free to download. ONO sells 1 one-off in-app purchase. Code Burst asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for ONO against 5.0 for Code Burst. That said, the two scores are not equally well evidenced: ONO has 9 ratings behind it against 1, so its average is the more settled of the two.

ONO ships an update every 2 months, Code Burst every 9 days. The most recent releases landed on September 10, 2026 and September 5, 2026 respectively.
