# JSON Tools vs BMI

The clearest difference is price: BMI at Free against JSON Tools's $2.99. BMI also leads on iOS requirement (12.0 vs 15.6). JSON Tools's advantage is chart position (#102 vs unranked). On ads, in-app purchases and device support there is nothing between them.

BMI is free to download; JSON Tools costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
