# Coordinates vs Gemma GPS

Coordinates's advantage is ratings volume (6.8K vs 1) and iOS requirement (15.6 vs 18.0). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Coordinates sells 6 in-app purchases, starting at $1.99 per month and Gemma GPS sells 2 in-app purchases, starting at $199.99 per year. Whichever you choose, the download price is not the number that matters.

Gemma GPS holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Coordinates has 6.8K ratings behind it against 1, so its average is the more settled of the two.
