# GPT.Zero vs GPTZero

The clearest difference is rating: GPTZero at 5.0 against GPT.Zero's 4.5. GPTZero also leads on monetization model (free with in-app purchases vs subscription) and update cadence (every 2 weeks vs every 2 months). GPT.Zero's advantage is ratings volume (75 vs 3). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. GPT.Zero sells 3 in-app purchases, starting at $6.99 per 7 days 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 4.5. That said, the two scores are not equally well evidenced: GPT.Zero has 75 ratings behind it against 3, so its average is the more settled of the two.

GPT.Zero ships an update every 2 months, GPTZero every 2 weeks. The most recent releases landed on November 5, 2026 and October 31, 2026 respectively.
