Ratings and Reviews


Doesn’t work

This app is so frustrating. I have the thermion XM38. The scope indicates that it is connected, but the app won’t see it when it comes time to connect. I turned my phone off and on. That got it to connect once, but recording to the phone didn’t work and when I was checking settings to see why, the app crashed and now it won’t connect again, even with turning phone on and off. I’ve also tried airplane mode after reading reviews, that doesn’t work either. It just won’t connect despite the scope being connected. I’ve also checked I have the most recent firmware and app version. It’s used as a selling point for the product, but I should have read reviews first, I wouldn’t have bought it, complete garbage app and ruins 90% of the reason I chose thermion over other options.

Worst App I’ve Ever Used

This app is so frustrating. It refuses to connect to my Trail XP50 unless I’m in airplane mode. I’ve also found that I can just disable cell signal instead of having to use airplane mode. I haven’t been able to successfully save to my phone or even view videos saved on my Trail. When I try to save a video to my phone, it just shows up in my camera roll as a blank video that won’t play. Videos will actually play within the app, but the time elapsed and remaining doesn’t work, there is no marker that shows how much video is remaining, and you can only pause—you can’t jump ahead—you have to watch the whoooole thing to see something at the end of the video. For such a wonderful and advanced scope, this app is absolutely just awful. Please, PLEASE fix this app!

No connection with apple devices.

Just purchased an XP 50 trail and helion. Love both optics for hunting but the stream vision app and WiFi signal of scope are apparently garbage. I can connect my WiFi from either Device briefly, meaning 3 to 5 seconds and then it drops the connection. I’ve even shut all other WiFi signals and data signals off in my house to eliminate any interference. Only the first time that I tried it did it work for a few minutes. Hope this is something they can fix or I have 8 grand worth of optics that do half of what they are advertising they can do.
