I'm currently using two apps and testing the Follow Me modes that are being added. I'd like to give my opinion on these modes in both apps. Keep in mind... these apps are changing weekly and in some cases, even daily. So this review is dated. Also, these are _my_ observations. Your mileage may vary.

This is my favorite app. I've used it several times for free flying and for Ground Station use. Both of these work very well and I have no complaints. I tried the Follow Me mode and it's somewhat lacking. In order to use GS or Follow Me you need to turn on "Enable Flight Control Modes" in the settings (the three dots in the upper right corner). You can then turn on Follow-me flight mode. However, this turns off the Ground Station Flights mode. You can only have one on at a time. It's kind of a pain to go into settings and select one or the other each time you want to change. There is only one option in the Follow Me settings and that is "Bering Accuracy (degrees)" (yes, it should be "Bearing"). I believe this is the angle that the drone flies in relationship to your controller. I have mine set to 30 degrees.
Follow Me... I just could not get it to work well at all. As I understand it, Follow Me mode uses a dynamic waypoint to follow the controller. It's updated every so often as the controller moves. It seemed like the update was _very_ slow. When it reaches a new waypoint it pauses. Sometimes I could not get it to move to the next location. Another issue I had was that it was not very accurate. In the video below I walk about 20' away from a tree. The drone then starts to fly _into_ the tree. As I see this I immediately click the S1 switch to Atti and back to GPS 40). It changes to Atti and then instead of going into GPS mode it starts to move right back to the waypoint in the tree. I do this several times, same result. I finally leave it in Atti mode and escape the tree monster. You then see me switch it back to GPS and it again wants to fly to that last waypoint 49). So it appears that there is an issue with getting it out of waypoint mode.
Disclaimer: In both of these videos I'm controlling the pitch of the camera. Nothing else.

I've only use this app for free flying and Follow Me mode. The layout of this app is very nice and clean. I like that the user can resize the video/map view to any size. The Follow Me mode... works perfectly for me. It tracks very quickly and accurately. A few times I tried to sneak away from the drone but it continued to follow me very well. To enter Follow me mode to click on the GS icon (I suspect turning it on) and then click the play icon with no waypoints set. Very easy. One current draw back to DJI's SDK release is that it won't allow you to turn video on/off while in GS mode (so this is true of all non DJI apps). This app has the GS icon right on the free fly screen. So you can turn the video on, click on GS and then go right into Follow Me mode. No need to go into settings and turn video on at launch. This makes the work around very simple.
For me, Follow Me mode works very well in this app. I could not find any issues. When I clicked into Atti and back into GPS, it stayed in GPS mode.
