# Gretio vs AegisOne App

Gretio's advantage is ratings volume (23 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Gretio sells 4 in-app purchases, starting at $19.99 per year and AegisOne App sells 1 in-app purchase, starting at $149.99 per year. Whichever you choose, the download price is not the number that matters.

AegisOne App holds the better App Store score, 5.0 against 3.8.
