This app is a fantastic way to view your R jpeg images and examine them in post. Find the problem and you can fix the problem? And not to mention, the support is phenomenal!

Response from developer

Hi Albert, Thank you so much for the kind words and the 5-star review! I built this app to make inspecting raw R-JPEG images as clean and straightforward as possible, so hearing that it helps you find and analyze issues is incredibly rewarding. I put a lot of personal care into providing prompt, genuine support for every user, and your feedback means more to my work than you know. Thank you for your amazing support and for being a part of this journey. Best regards.

Response from developer

Hi, Just a quick follow-up: the update with full support for InfiRay camera formats has been live on the App Store for a while now! Please make sure you are on the latest version of Thermal Viewer. The image engine now seamlessly parses InfiRay JPG files and accurately extracts all temperature data. If the app is working smoothly for you now, I would really appreciate it if you considered updating your rating to reflect the fix. Best regards.
