# LumiCalc vs Gradation Calculator

The clearest difference is in-app purchases: Gradation Calculator at none against LumiCalc's 1. LumiCalc's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 18.2). On price and ads there is nothing between them.

Both are free to download. LumiCalc sells 1 in-app purchase, starting at $2.99 per month. Gradation Calculator asks for nothing beyond the download.
