A one-trick pony, but it’s a neat trick. You pop your thumb on a pad to measure heart rate, blood oxygen and breathing.
The smart bit comes from the Tinké app, which turns these measurements into two different ratings – a Vita rating for for wellness, complete with calming breathing exercises for relaxation. It’s tiny, the size of a matchbook, and you can share results with the Tinké community.
There are two versions – one for Apple (plugs into Lightning connector), the other for Android devices (connects wirelessly via Bluetooth). Free shipping to 30 countries is available.
