# GPTZero vs GPT.Zero

The clearest difference is review sentiment: GPTZero at 70% against GPT.Zero's 0%. GPTZero also leads on monetization model (free with in-app purchases vs subscription) and update cadence (weekly vs every 2 months). GPT.Zero's advantage is rating (4.6 vs 4.3). On price, ratings volume, 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 GPT.Zero sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

GPT.Zero holds the better App Store score, 4.6 against 4.3. Both are backed by a comparable volume of ratings — 135 and 71 respectively. Written reviews complicate that: 70% of GPTZero's written reviews are positive against 0% of GPT.Zero's, so the app with the better star average is not the one people write more warmly about.

GPTZero ships an update weekly, GPT.Zero every 2 months. Both last shipped on October 25, 2026.
