# Trinim vs Echo

The clearest difference is in-app purchases: Trinim at none against Echo's 1. Trinim also leads on ads (none vs shown) and iOS requirement (14.0 vs 17.0). On price and device support there is nothing between them.

Both are free to download. Echo sells 1 one-off in-app purchase. Trinim asks for nothing beyond the download.
