# AxCalc vs AnestSync

The clearest difference is monetization model: AnestSync at free against AxCalc's paid. AnestSync also leads on review sentiment (100% vs 63%). AxCalc's advantage is device support (4 vs 1) and iOS requirement (9.0 vs 16.4). On price and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
