Verdict
The clearest difference is rating: Scanner at 4.9 against Readonly's 4.4. Scanner also leads on monetization model (free vs free with in-app purchases) and iOS requirement (14.0 vs 16.0). Readonly's advantage is update cadence (every 3 weeks vs every 8 months). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Scanner sells 3 one-off in-app purchases and Readonly sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Scanner holds the better App Store score, 4.9 against 4.4. Both are backed by a comparable volume of ratings — 13 and 16 respectively. Written reviews complicate that: 96% of Scanner's written reviews are positive against 100% of Readonly's, so the app with the better star average is not the one people write more warmly about.
Scanner ships an update every 8 months, Readonly every 3 weeks. Both last shipped on November 3, 2026.
