WELT Smart Belt, Compatible with iOS and Android, Adjustable Size Men's Leather Belt, Bluetooth 4.1, Smart Fitness Activity Tracker, Wearable for Healthcare, Waist Measurement, Step Counter (Black)

The Welt is an interesting idea, but unfortunately just doesn’t perform. The fact that the user has to cut the belt to size is terrible. The belt frays and is difficult to cut properly. The instructions are painfully vague. The app is not accurate and half the time cant find the belt (when it’s around my waist and I’m holding my phone - you’d think thT would be close enough). Too bad, because it is a really great idea. Just needs more work.

Love Welt it’s amazing and the technology built in this is awesome., it tracks your sitting and steps and has the ability to tell you if you have eaten too much. It syncs with the app and gives you all the required info to control you food Intake and ideal time. It’s the best tech belt out there and I just love it they will be sync with apple health soon which will raise the bar believe me get one and you want be buying any belt. The quality is superb.

Definitely worth it. I've been using it more than a month, (the battery still has 50% left) and I gotta say, I'm quite satisfied.It's definitely providing more functions than a fitbit, and I'm actually getting to watch my weight. Plus, its quality as a leather belt (I think) is top notch.The app needs some major design improvements though, but it gets updated quite regularly. So I guess it will improve.

Whether or not this thing is useful, whoever made the image with the measurements doesn't know how belts work. The furthest hole out is labeled as 30 and the size increases as you cinch the belt. That's poor quality right out of the gate.

Welt is an innovator in smart tracking, as evidence by these belts. In 2019, Welt, with the help of GI doctors at the Mayo Clinic, are putting on the market insertable fitness tracking devices. Just place a freshly lubed device into your anus just after your AM void, and you will have accurate readings all day.

The battery lasts for a super long time. More than a month. The functionality is quite nice. It measures the steps very accurately than fitbit. And the design is also fine, it goes well any clothes only except sportswear. HOWEVER, the firmware updates quite slow....Although the price is slightly expensive, but still worth it.
