Partly genius, partly meh

I love the temp overlays and some of the functionality of this app.
Couple problems:
The camera is pretty unstable on my iPad mini (latest version) - it does come on, but I have to reinsert the camera pretty often to get it back to work after image either freezes or turns black (rest of app stays responsive)
- speaking of iPad, why is no iPad-specific version compiled.? Seems like a pretty low hanging fruit
- Rotation of all controls should work in all directions (portrait/landscape/up-side-down) to provide needed flexibility to get the most out of this camera
- why does the app not use present Lidar sensor and asks me to enter distance manually..?
- does the AI feature actually do anything..?
Hopefully you guys can address at least some of these concerns to make this app the greatest companion the device deserves

Doesn’t work with iPhone

Update. After working with tech support, I figured out you *must* set Wired Accessories = Automatically Allow When Unlocked for the iPhone to recognize the IR camera. If you choose Always Ask instead, the iPhone/camera handshake fails every time.

Original post: Been waiting for nearly 3 months for them to enable operation on iPhone with USB-C port. Is not a priority for them

Good Price, Great Results

Just a home owner / handyman for friends. This is great and simple. Maybe it’s missing something for professional, but makes it so easy to see cold or hot spots. See missing insulation, studs, air ducting. Does everything I need with great value.

Stopped working on iPhone 16 Pro

Not sure why, but this no longer works on iPhone 16 Pro. Still works ok on iPad Mini A17 Pro. Very frustrating.
