PIX4Dcapture is a free drone flight planning app that allows you to map and model using only your mobile phone. You can fly DJI and Parrot drones, trigger RGB, multispectral, and thermal sensors, and fly missions online or offline. Pix4D software in the cloud automatically processes images uploaded from your device, and you can select your drone from DJI, Parrot, or Yuneec. The PIX4Dcapture app includes five different missions, so you can easily map areas of all sizes. You can customize mapping parameters like image overlap, camera angle, and flight altitude to suit your needs.
