# EMF Scan vs GPS Speedometer

The clearest difference is in-app purchases: GPS Speedometer at none against EMF Scan's 1. GPS Speedometer also leads on ads (none vs shown). EMF Scan's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.0). On price there is nothing between them.

Both are free to download. EMF Scan sells 1 one-off in-app purchase. GPS Speedometer asks for nothing beyond the download.
