I was a faithful user of the original booster app, it for sure increased range in my area. This new version added the FPV pilot tab which is a very impressive and creative use of the new DJI SDK. I really like the new map views and the killer feature is that they used Google Maps which are easily 2 years newer than the Apple maps that the DJI app uses. In my area they are VERY crisp and VERY recent!! This was well worth the modest price. I cant wait for the next version to come out, even more useful features comming from this team! Edit, Ive been now using v3.1 and 1- the added "WiFi Wand" is VERY useful with high gain antennas on the TX, to tell you exactly where to face the model. This also helps you to spot the model at greater distances as you know just where to look. Also it changes color based on the WiFi Strength. 2- The added Battery Gague with remaining flight time based on real-time load is also a loved feature. 3- The new gesture to tilt camera is now a very excellent feature. You can now fine tune exactly how fast the camera tilts in flight. The variable gain slider coupled with the variable touch gesture give you precise control. No more distracting camera jerks while shooting video. 4- Flight Tracker, I like the icon choices, animated Phantom or Arrow, I like the arrow as its easier for me to watch the model heading when playing back. The tracker also displays the results of bad GPS data in the tracks, very interesting visually see that GPS data isnt always perfect. They added a filter switch to hide any GPS anomalies that you may see. Being able to see logs of all flights is great and Im impressed with all the telemetry data is available, even total current draw at all points in the flight! All in all FPV Booster is now my favorite app for the Vision+ and its still being developed, so there will be more to come!
