You can also plan your flight route and find out the elevation change & how much battery you'll have left! You can view the area map and see No Fly Zones, Terrain Elevations, Sunrise/Sunset Times & Positions plus you can also see an animated Wind Map, showing the wind direction with colour coded arrows so you can immediately see if its too windy to fly or not. Drone Starts calculation are also based on your drone model*, so things such as winds speeds and battery range are calculated using your actual drone!

Verdict
The clearest difference is ads: Drone Start at none against EMF Radiation Detector Reader's shown. Drone Start also leads on update cadence (every 3 weeks vs every 7 months) and iOS requirement (13.0 vs 15.6). EMF Radiation Detector Reader's advantage is rating (4.5 vs 4.1) and ratings volume (4.7K vs 47). On price, in-app purchases, monetization model and device support there is nothing between them.
