iWarmU 4+

Ignoring the poorly translated interface, upon the first few uses of the app it worked flawlessly. However, after the third or fourth use one sock continuously connects and disconnects, even though both batteries will still heat the socks when pressed manually. Not sure if it’s the software or a defective Bluetooth transmitter, but none the less it has been frustrating. I paid 60$ for these socks so I’m going to keep using them. It’s been beyond frustrating however lifting up my pants and opening the battery sleeve every time I want to change the heat setting.

The socks themselves are great. But the app is an embarrassing piece of junk! It only works *sometimes* and even when it does, it’s the WORST app I’ve ever used for connecting and controlling a Bluetooth device.

1.) You can *set* the temperature you want your socks to reach, but the app doesn’t show you their *current* temperature, so you can’t even tell if it’s reaching that temperature.

2.) The app doesn’t show current battery level. It only shows you when the batteries are about to die. So you have to pull your pants legs up and unbutton the sock compartment every time you want to check how much is left. (it’s measured in quarters, so it shouldn’t be hard. The Ember mug app shows the *precise* battery level from 1% to 100%, so certainly the 4 dot system should be easy)

And it can’t even be paired with more than one set of sock batteries. If you have two pair of socks and want to change them, or even just switch batteries while the other set is charging, you have to go through the painful searching, failing, and finding process multiple times. Every. Single. Time.

PS: Registration is a JOKE. The onetime verification email (or text) is NEVER sent, no matter how long you wait or how many times you tell it to resend. MADE IN CHINA. Need I say more? 😒

Tried to register, doesn’t do anything when I hit register. USA was difficult to find. Keeps activating one sock and not the other.m, when not in use. App basically needs more attention. Socks work great though. Can’t really complain. Keeping them of course.
