# GLO vs Engineering AI

The clearest difference is price: GLO at Free against Engineering AI's $3.99. GLO also leads on ratings volume (29 vs 1) and iOS requirement (13.0 vs 26.0). Engineering AI's advantage is rating (5.0 vs 3.0). On update cadence, ads, in-app purchases and device support there is nothing between them.

GLO is free to download; Engineering AI costs $3.99 up front. GLO sells 10 in-app purchases, starting at $2.99 per 7 days and Engineering AI sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Engineering AI holds the better App Store score, 5.0 against 3.0. That said, the two scores are not equally well evidenced: GLO has 29 ratings behind it against 1, so its average is the more settled of the two.

GLO ships an update weekly, Engineering AI every 9 days. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
