Verdict
The clearest difference is review sentiment: Scanner App at 100% against Highlights's 53%. Highlights's advantage is ads (none vs shown) and ratings volume (1.6K vs 7). On price, update cadence, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Highlights sells 3 in-app purchases, starting at $4.99 per month and Scanner App sells 4 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Highlights holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Highlights has 1.6K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 53% of Highlights's written reviews are positive against 100% of Scanner App's, so the app with the better star average is not the one people write more warmly about.
Highlights ships an update fortnightly, Scanner App every 2 weeks. The most recent releases landed on September 25, 2026 and June 4, 2026 respectively.
