# Interlocked vs ONO

The clearest difference is in-app purchases: Interlocked at none against ONO's 1. Interlocked also leads on ads (none vs shown) and ratings volume (1.5K vs 9). ONO's advantage is update cadence (every 2 months vs every 49 months) and rating (5.0 vs 4.8). On price, review sentiment and device support there is nothing between them.

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

ONO holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Interlocked has 1.5K ratings behind it against 9, so its average is the more settled of the two. Written reviews point the same way: 97% of Interlocked's written reviews are positive against 100% of ONO's.

Interlocked ships an update every 49 months, ONO every 2 months. Both last shipped on September 29, 2026.
