# Pipe Calc vs OFFSET

The clearest difference is in-app purchases: Pipe Calc at none against OFFSET's 1. Pipe Calc also leads on device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price and ads there is nothing between them.

Both are free to download. OFFSET sells 1 one-off in-app purchase. Pipe Calc asks for nothing beyond the download.
