# Change vs FormCheck AI

The clearest difference is price: Change at Free against FormCheck AI's $0.99. Change also leads on review sentiment (81% vs 58%) and ratings volume (49 vs 2). FormCheck AI's advantage is rating (5.0 vs 4.6) and update cadence (fortnightly vs monthly). On ads, in-app purchases, monetization model and device support there is nothing between them.

Change is free to download; FormCheck AI costs $0.99 up front. Change sells 12 in-app purchases, starting at $1.49 per month and FormCheck AI sells 6 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

FormCheck AI holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Change has 49 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 81% of Change's written reviews are positive against 58% of FormCheck AI's, so the app with the better star average is not the one people write more warmly about.

Change ships an update monthly, FormCheck AI fortnightly. The most recent releases landed on September 25, 2026 and September 23, 2026 respectively.
