The app doesn’t see the device. ### 2/5 — Upside down ! *2026-03-05, version 2.0.1* The only way to get full screen on the iPad 10 is to hold the iPad upside down. And although the image becomes full screen the text is still upside down regardless of the settings I use. This really needs sorting. It’s basic stuff. ### 1/5 — Does not support IOS 26 or later *2026-01-30, version 2.0.1* At least its in my return window. ### 3/5 — Does not work with iPhone 17 *2025-12-29, version 2.0.1* Worked great with previous phone. I tried a speed to usb-c connector and it will not work. ### 1/5 — Doesn’t work for iPhone 17 *2025-12-19, version 2.0.1* Doesn’t work for iPhone 17… ### 1/5 — Doesn’t work on iPhone 17 pro max *2025-12-15, version 2.0.1* Isn’t recognizing the infiray on usb c for iPhone 17 pro max. ### 1/5 — No usbc support *2025-10-03, version 2.0.1* Still does not support the usbc camera ### 2/5 — Lightning connection *2025-04-15, version 2.0.1* Lighting/Apple connection only works with direct connection. I had to upgrade my iPhone and the old thermal camera only works when connected direct to lightning. A lightning > USB-C adapter doesn’t work. 🙁 ### 1/5 — Doesn’t work *2025-01-21* Doesn’t work with USB C connected apple products, just a scam. ## Frequently asked questions about Thermal P2 ### What does the Thermal P2 app do?
