# GPTZero vs GPTZero

The clearest difference is rating: GPTZero at 5.0 against GPTZero's 4.3. GPTZero's advantage is ratings volume (135 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. GPTZero sells 5 in-app purchases, starting at $7.99 per month and GPTZero sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

GPTZero holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: GPTZero has 135 ratings behind it against 2, so its average is the more settled of the two.

GPTZero ships an update weekly, GPTZero every 2 weeks. The most recent releases landed on October 28, 2026 and October 25, 2026 respectively.
