Review on Digital Wireless Hydrometer Thermometer Smartphone Kitchen & Dining by Jennifer Franks

For some reason it's low. On brew day the tilt might read 1.044 when my hydrometer (actually two hydrometers) reads 1.050. Towards the end of fermentation it shows somewhere between 1.002 and maybe 1.005, which is probably 0.006 lower than Hydros. Frustrated, I calibrated it after just one use. For $139 I hope I don't have to tell Tilt what gravity is. it should tell me! Also, the sizing process is brutal and my wife wants to know what happened to all the sugar. However, the calibration process went smoothly and Tilt read the calibration solution correctly. But on the next brewing day it again showed a low level compared to both hydrometers. For those who want to track progress, see temperature rise, gravity decrease, and three days of inactivity so you know the fermentation is complete (and can view everything), this works. If you wanted to spend money and knew the best time to do so, I personally couldn't count on it because of this discrepancy. Maybe I'll sell it to another brewer who likes to tinker.
