# CastOn vs scanner app pro

CastOn and scanner app pro both sit at 4.5 stars, but that hides the real split: 100% of scanner app pro's written reviews are positive against 37% of CastOn's. scanner app pro also leads on ads (none vs shown). CastOn's advantage is ratings volume (5.2K vs 18). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. CastOn sells 11 in-app purchases, starting at $4.99 per 7 days and scanner app pro sells 4 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

CastOn holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: CastOn has 5.2K ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 37% of CastOn's written reviews are positive against 100% of scanner app pro's, so the app with the better star average is not the one people write more warmly about.

CastOn ships an update every 3 weeks, scanner app pro fortnightly. The most recent releases landed on September 26, 2026 and September 8, 2026 respectively.
