Heart rhythm on demand
Rest two fingers on the electrode ring and hold still for 30 seconds. The trace and the reading are saved to the app, and you can export the session as a PDF to take to an appointment.
Tarcet · Pulse Band
No screen to distract you. The band sits flat against your wrist, takes the measurements, and keeps them in the app until you want to look.
Black — graphite case, ribbed silicone strap. Ships with a woven stretch strap.
What it reads
Each one is a different shape. The band samples through the day and builds a baseline for you, so a change is easy to spot.

Variability between beats tends to fall when you are short on sleep, fighting something off, or training hard. Watching your own trend is more useful than comparing the number to anyone else's.
Skin temperature drifts with your cycle, your recovery and the room. The band samples overnight and shows the deviation from your own baseline rather than a clinical figure.
Light, deep and REM, plus the times you woke up. Because there is no screen and no rigid case, most people forget they are wearing it — which is the only way sleep tracking works.
Wearing it
The case is thin and curved, so it sits under a shirt cuff and does not catch on a sleeve. Sensors face the skin; nothing faces out.
Movement
Start a session from the app, or let automatic detection pick up a walk or a run after a few minutes and log it for you.
Distance and pace come from your phone's GPS while it is with you.

Questions
No. The Pulse Band is a wellness and fitness tracker. Its ECG, blood pressure and temperature readings are estimates meant to help you notice your own patterns. They are not diagnoses and should not be used to make decisions about medication or treatment. If something in your readings worries you, or you feel unwell, talk to a doctor.
It is a trend, not a clinical measurement. The band estimates blood pressure from pulse signals, and it works best once you have calibrated it against a proper cuff monitor in the app. Treat the number as a direction of travel, and use a cuff when an exact figure matters.
Everything lives in the companion app, which syncs over Bluetooth whenever your phone is nearby. The band itself signals with vibration. That is the trade: no screen means a thinner case, a longer charge and nothing lighting up at 3 a.m.
Silicone for training and water, woven stretch for sleep and everyday wear. Both are in the box, and they release with a push tab — no tools, no pins.
