# Scanner App vs Nerve

The clearest difference is in-app purchases: Scanner App at none against Nerve's 5. Scanner App also leads on iOS requirement (16.6 vs 18.6). Nerve's advantage is update cadence (every 4 days vs every 3 weeks) and ratings volume (15 vs 3). On price, rating, ads and device support there is nothing between them.

Both are free to download. Nerve sells 5 in-app purchases, starting at $0.99 per 7 days. Scanner App asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Scanner App against 4.9 for Nerve. That said, the two scores are not equally well evidenced: Nerve has 15 ratings behind it against 3, so its average is the more settled of the two.

Scanner App ships an update every 3 weeks, Nerve every 4 days. The most recent releases landed on October 5, 2026 and October 2, 2026 respectively.
