It would make it so much easier to relate if you could back up your issues with some examples, after all its extremely easy to share from these product video or photos.
and since you don't write what host / or even standard (IOS or Android) you using it on, it gets even more difficult to relate.
Thermal cameras and particularly budget smartphone one's where their so extremely many varieties hence the host (phone) it not just plug and play, there are often many factors in play to use such product and get the optimal result like you fx see from others and particularly with Seek's product there is all dependent on the sensor and doesn't have a standard camera to lean on and use this gimmick as a make-up, like edge detection etc in regards to enhancing the result.
What system are you using and which phone? and have you tried on other mobile devices?
Have also taken the plunge on a Seek pro, and purchased it privately (socalled new) så that certainly also a risk, but that's pretty much the only option from here Denmark, as a Seek pro cost 800 to 850USD here on regional stores, after taxing and another +25%VAT on top and up there in price there is better alternatives..
Went for IOS as that was the only option for purchase at 290USD + minor shipping fee from US (no tax, private low declared) and had to go out and purchased a freaking IPAD 2018 as I didn't have any Items with lightning port.
Anyway just got it and here is some examples of the results I'm getting from a noob point of view and 290USD investment.
