content: Hi. I have an Opgal Therm-App Hz (25 Hz. version) which I bought in 2019. I was diagnosing a problem with some unrelated electronics today, and connected the Therm-App to my phone. I was depressed to find that both the Opgal's app (Therm-App) and a third-party App (Therm App Plus) had vanished from my phone and from the Google Play store. I tried downloading the APK from another third-party App (ThermViewer) but it won't install on my Pixel 9 Pro (Android 16). Has Opgal hung all of us Therm-App users out to dry? It was a $1,000 device, so it would be nice if I could still use it. Thanks.

content: I got a 8.7 hz and use it on a modern Xiaomi 15pro phone. The ThermApp version is "2.6.28-05", hope this help.There are many versions on the internet I tried and they did not work. On Xiaomi 15pro I need to tun on the "Google Services Framework" feature, something like that, otherwise this App will keep crashing.

content: That's the curse of anything depending on a phone – sooner or later, the manufacturer will lose interest and the device is effectively bricked. Sometimes, we are in luck and somebody has reverse engineered the protocol and written an open source tool to use the thing with your computer. I typically search github in such situations.Keeping my fingers crossed.

content: I agree wholeheartedly with Phil, but I would have hoped for better, given the cost of these devices. It's so frustrating when you have perfectly good hardware that is made useless by changes in surrounding software.ThermApp version i2.6.28-05 is the app that reliably crashes ten seconds after I start it. Can you (RRTheOne) give me more detail on what you did with Google Services Framework (a core Android component that always runs in the background) to stop the app from crashing? I'd love to be able to use my thermal imager again.That said, what Ireallywant it to run one of the two high-quality third party apps (ThermApp Plus or ThermViewer). If anyone knows how to do this on a modern phone (or even knows where I can get the APK for ThermApp Plus, which I paid for) please speak up. Thanks!

content: Your timing is not good at all-Therm App 's native app still runs- (I have it)Therm app plus- which is the most capable bit of software i've ever seen with a thermal camera- i had bought it and have it, but when i install it on new phones now , it reaches out ot the server set up for it and fails- I actually HAVE reached out to the developer, and am hoping to convince him to update it to 64 bit app status so it works on modern phonesTherm viewer...is weird. It doesn't seem to fully work on more recent phones either, but i don't know if that's as solid a thing- but the dev mentioned it's hit or miss on newer phones....--owner of a therm app hz and therm app pro , worried about my collection of old phones that can run the cameras becoming too old and dying....

content: Hi Dark Volter,Thanks for the detailed information. The native app only runs for ten seconds at a time on my phone (Pixel 9 Pro, Android 14). Therm Viewer does run on my wife's phone, which is five years old (One Plus 8, Android 13). I could buy an old phone specifically to run Therm App Plus (it used to run on my Pixel 6), but that's not optimal. If you can convince the author of Therm App Plus to update it, I'd cheerfully pay for it again! I could contact him too, if you think that would help. In the meantime, could you you point me to the APK for the final version. I didn't save it when I got the Pixel 9, and can no longer get it from the Google Play Store (where I originally bought it). These devices (Therm App) are too cool to abandon.Thanks,Josh

content: The two issues I am seeing now, are that on new installs( DO NOT UNINSTALL THERM APP PLUS ON A PHONE IT'S WORKING ON, TO TEST THIS) - it reaches out to the server to validate the camera, and the server is down, so right this second, new installs are impossible. I did mention it to the dev, Bill, but this is a new and separate issue from it not installing on Android 14 onwards( which I also mentioned to the dev, who said he works look into it)It would probably help a lot to have more than just me reaching out, I will message you their email address since it's not on the internet on their thermal camera bird watching site anymore

content: Use adb to grab the APK off of the phone and back it up if you want, though there are also some downloads here:https://apkpure.com/therm-app%E2%84%A2/com.thermappYou might be able to transfer the cache to retain the registration, or find a way to hack around it, not sure (probably need rooted device).Android 14 does break a lot of apps with newly added security requirements.
