Product review (2 stars): Honestly, I just don't understand the point of this device
I rarely post reviews on products, but felt compelled to share my thoughts with anyone considering purchasing this device. I recently purchased the Humiditrak as a way to monitor the humidity of a very expensive Martin acoustic guitar. I live in New England and work about 20 miles from home. It seemed like a great idea to be able to access an app and "see inside" my guitars case. What is not clear (to me anyway), is your smartphone needs to be within 100 FEET of the sensor for you to get updates (it does store them so you can review them after the fact). Honestly, I just don't understand the point of this device. If I'm home, I can check the humidity of my guitar by walking upstairs (if I'm, let's say, making a snack in the kitchen). I imagine the only real reason you would want a product like this is to monitor the humidify when you are away from your home, I'm I right? To be fair, you can install the app on a second device (like your "spare" iPhone), leave the app open and pull the data from the cloud (as the second device is uploading it). Haven't tried that yet and it sounds like a pain in the butt.

I gave it two stars because if you do read the instructions within the app, it does tell you the second device "trick." Also, it seems to accurately record the humidity and temp. Also, it does store those metrics throughout the day, so maybe if you care what the humidify was, say, 8 hours ago, the Humiditrak is for you (I guess if you want to look at long term humidity trends?). For me, maybe I just totally misunderstood the limitations of this product, so I guess that's my fault. However, if you purchase this product, knowing you need to be within 100 feet of the sensor, I'd love to know why...
