# RM vs 1RM

The clearest difference is in-app purchases: RM at none against 1RM's 1. RM also leads on ads (none vs shown) and iOS requirement (10.0 vs 12.0). On price and device support there is nothing between them.

Both are free to download. 1RM sells 1 in-app purchase, starting at $0.99 per 7 days. RM asks for nothing beyond the download.
