# Sarotis vs NFC Book

The clearest difference is ads: Sarotis at none against NFC Book's shown. NFC Book's advantage is update cadence (every 3 days vs every 6 weeks) and iOS requirement (11.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Sarotis sells 4 in-app purchases, starting at $1.99 per month and NFC Book sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Sarotis ships an update every 6 weeks, NFC Book every 3 days. The most recent releases landed on October 26, 2026 and October 7, 2026 respectively.
