### 1/5 — 4K pro

*2026-07-26, version 2.4*

App won’t connect to scope since the app updated

### 1/5 — Doesn’t work

*2026-02-09, version 2.2*

Won’t connect to scope

### 4/5 — Connection steps

*2026-01-26, version 2.2*

This is a nice app. It keeps you from having to look into the scope for long periods of time especially when you want to change settings. I called tech support and they helped me work through the WiFi connection process. The manual doesn’t make it easy to connect the app to the scope. Once you connect the first time, it’s easy to reconnect and get back into the settings.

### 1/5 — Atn equipment

*2026-01-01, version 2.2*

This app and the Thor 4 is equally trash

### 1/5 — Disconnects

*2025-11-15, version 2.2*

The app is constantly disconnecting from x sight using it on iPhone 15. I loaded the app on iPad and it works fine.

### 5/5 — ATN 4k Scope

*2025-11-11, version 2.2*

So I bought my scope on Amazon last year and fell completely in love with it. Talk about dead on. So this year I went to use it and the third time the screen would not power on, I contacted customer support , they talked me through a fix, which did not work. They had me send my scope to them and they sent me a brand new replacement still wrapped in the box. A+++++++++ service. I highly recommend any ATN product. THANK YOU ATN!!!!!

### 3/5 — Scope is great app not so good

*2025-06-14, version 2.2*

When I try to stream on my iPhone it always disconnects from the scopes WiFi

### 3/5 — Fixed crosshairs on live view

*2025-03-22, version 2.1*

They fixed the crosshair overlay on live view. THANK YOU!

### 3/5 — Thor 4 640x480

*2025-03-17, version 2.1*

App. And connection are not real stable. Using IPhone like the new widgets and ability to zoom with app. Hoping for better stability in future upgraded.

### 4/5 — A step in the right direction ATN!!!

*2025-03-16, version 2.1*

Whoever was recently hired to (or fired from) ATN’s app development team hats off to you!  Thank you for the added features! The only reason why I didn’t give it 5 stars is because the app occasionally freezes causing me to reboot my iPad.  Overall this is a huge step in the right direction for obsidian 4 and ATN!  Thank you 👍✌️
