# Empty vs BMI Calculator

The clearest difference is in-app purchases: BMI Calculator at none against Empty's 1. BMI Calculator also leads on ads (none vs shown). Empty's advantage is iOS requirement (15.6 vs 17.6). On price and device support there is nothing between them.

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