Smartwatch - FitiWatch Client Reviews 2026 Sleep tracking is automated—you just wear the watch to bed, and it detects when you fall asleep and wakes up, then breaks down your sleep into light, deep, and REM stages. Battery life is rated at 3-5 days depending on usage—if you use the heart rate monitor continuously and get a lot of notifications, it'll be closer to 3 days, but if you're a lighter user, you might get 5 days. Charging takes about 2 hours via the included magnetic charging cable. The design is unisex and comes in a few color options, so you can pick one that matches your style.
Smartwatch - FitiWatch Client Reviews 2026 These include an optical heart rate sensor, which uses green and red LEDs to shine light into your skin and measure the amount of light that's reflected back. Every time your heart beats, blood flow changes, and the sensor detects those changes to calculate your heart rate. This is called photoplethysmography (PPG), and it's the standard method used in most smartwatches and fitness trackers today. The whole experience is designed to be as frictionless as possible, so you can just wear it and forget about it until you need to check your stats or get a notification.
