# eFRS vs Calculator Max

The clearest difference is in-app purchases: eFRS at none against Calculator Max's 1. eFRS also leads on iOS requirement (13.0 vs 15.6). Calculator Max's advantage is device support. On price there is nothing between them.

Both are free to download. Calculator Max sells 1 one-off in-app purchase. eFRS asks for nothing beyond the download.
