# ChatGPT vs Scan

The clearest difference is price: ChatGPT at Free against Scan's $2.99. ChatGPT also leads on ratings volume (12M vs 2) and chart position (#1 vs unranked). Scan's advantage is in-app purchases (none vs 9) and ads (none vs shown). On rating and device support there is nothing between them.

ChatGPT is free to download; Scan costs $2.99 up front. ChatGPT sells 9 in-app purchases, starting at $8.00 per month. Scan asks for nothing beyond the download.

Scan holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: ChatGPT has 12M ratings behind it against 2, so its average is the more settled of the two.

ChatGPT ships an update every 6 days, Scan daily. The most recent releases landed on November 4, 2026 and October 31, 2026 respectively.
