The beta version of the app is available to dowload without restição use? or what rules?
you can freely use the beta version of the app following instructions on: https://support.pix4d.com/hc/en-us/articles/hc/communities/public/questions/204542545–Android-Beta-Phantom-3-Professional-Advanced-and-Inspire-1?locale=en-us
However the beta app is not entirely stable: there were some severe issues on DJI side with their SDK, both for Android and IOS: basically they were advertising that it would work out of the box, but they had some issues that made their SDK crash during flight. Our developpers are right now at DJI’s office for a hackaton to help them fixing this, and that should make things move forward.
A workaround for now is to update your P3 to the latest firmware version (to fix a geotagging issue), and then use DJI Pilot app and try to fly as much as possible in a grid pattern using a timer for the camera. Then transfer the image from the sdcard to your computer and use Pix4Dmapper to process your imagery.
In parallel to that, we have another team that has been working hard adding exciting new features to the capture app, but we will unveil them only once the P3 & I1 will work flawlessly.
