Simplicity was kept in mind when we made the Smartwatch™.
The Smartwatch™ is compatible with every single phone except Chinese Huawei phones.
Our readings are 99% accurate, but we don't compare ourself to expensive medical equipment.
The Smartwatch™ is waterproof. You can shower with it no problem. The maximum depth in water is 1 meter for 30 minutes.
A simple step-by-step guide is included in the packaging.
