# Glass vs BioAi

The clearest difference is rating: BioAi at 5.0 against Glass's 4.7. Glass's advantage is ratings volume (30 vs 3). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Glass sells 10 in-app purchases, starting at $6.99 per 7 days and BioAi sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

BioAi holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Glass has 30 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Glass ships an update every 10 days, BioAi fortnightly. The most recent releases landed on October 30, 2026 and November 5, 2026 respectively.
