# FormCheck AI vs PDC Performance

The clearest difference is price: PDC Performance at Free against FormCheck AI's $0.99. PDC Performance also leads on update cadence (every 2 days vs fortnightly) and ratings volume (9 vs 2). FormCheck AI's advantage is rating (5.0 vs 4.3). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.

PDC Performance is free to download; FormCheck AI costs $0.99 up front. FormCheck AI sells 6 in-app purchases, starting at $1.99 per 7 days and PDC Performance sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

FormCheck AI holds the better App Store score, 5.0 against 4.3. Both are backed by a comparable volume of ratings — 2 and 9 respectively. Written reviews complicate that: 58% of FormCheck AI's written reviews are positive against 60% of PDC Performance's, so the app with the better star average is not the one people write more warmly about.

FormCheck AI ships an update fortnightly, PDC Performance every 2 days. The most recent releases landed on September 23, 2026 and September 19, 2026 respectively.
