# Avenza Maps vs Ondago

Avenza Maps and Ondago both sit at 4.8 stars, but that hides the real split: 90% of Ondago's written reviews are positive against 52% of Avenza Maps's. Ondago also leads on iOS requirement (12.0 vs 16.0). Avenza Maps's advantage is ads (none vs shown) and ratings volume (127K vs 28).

Both are free to download. Avenza Maps sells 13 in-app purchases, starting at $32.99 per year and Ondago sells 16 in-app purchases, starting at $14.99 per year. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for Avenza Maps against 4.7 for Ondago. That said, the two scores are not equally well evidenced: Avenza Maps has 127K ratings behind it against 28, so its average is the more settled of the two.
