-[http://www.humanvethermography.com/ Pr José Travossos Valdez] integrated this camera into his medical protocol previously with classical infrared camera. Despite a little additional manual operation, quality and efficiency of the device allows him to produce usable thermogram in order to diagnose patients. In addition, integration of the images from Seek thermal to his medical analysis software doesn't cause any problem. Then tomorrow, all doctors with a micro infrared camera into pocket?

	For temperature, min/max mode shows here his limit but on a difficult case but if we check the spots, FLIR see colder point 18°C in place of 20°C for the Seek and 45°C in place of 47°C for the maximum, question about emissivity is open then, the emissivity point of reference of the Seek is unknown. This demonstrates a problem with min/max betwen FLIR says 16.7°C minimum and 63.1°C for the maximum. Anyway, when checking the same spot location with both cameras, results are really very similar, this can be considered as an excellent result for a micro camera.

-Conclusion: this camera seems having a precision around the dergree and is requesting minimally 5 degrees of thermal range to be efficient, black and white mode produces readable video, les easy when using other schemes.

 Seek thermal is absolutely not a toy, it is an already very serious device and we can open some light improvment in a near future that this creates a new kind of thermal standard.

 Regarding [http://therm-app.com/product/therm-app-device/ Therm-App], situation is quite more debating, it seems possible to edit thermogram, they have a resolution of 384x288 pixels, you have already two choices of lenses and his sensitivity is 0.07°C but this device is coming from army and is adapted to Israel weather and security purpose, this seems not having a dual mode digital/thermal mode, less color scheme and a very low temperature range from 5°Cto 90°C. Well, on other side, pricing can't be compared, starting around 3000$ in 2014, it is sold around 1600$ actually in 2015, then it is clearly a budget issue and with a cost very similar to regular thermal camera because cost of smartphone must be added too. The other advantage is that Thermal-app is available worldwide and Seek only in North America but, here, it exists clearly a cost question and Seek thermal offers a quite better deal regarding other advantages except for sensitivity. Not available for Iphone too.

 Really compact, you plug it directly on the USB portof most of the last 2014 and 2015 smartphone and running Android 4.3 and iOS 7.0, preferably with Samsung, HTC, Google Phone and Motorla (better top check compatibility's list on: http://www.thermal.com/supported).
