# Audio Calculator vs Satellite Tracker / Radar

The clearest difference is price: Satellite Tracker / Radar at Free against Audio Calculator's $9.99. Audio Calculator's advantage is ads (none vs shown) and iOS requirement (13.4 vs 15.6). On in-app purchases and device support there is nothing between them.

Satellite Tracker / Radar is free to download; Audio Calculator costs $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.
