The app
Everything else happens in the LEEK app
The band is set up through the LEEK app, built in cooperation with Syrax. It shows recovery, strain and sleep in one view, guides your training – and stores nothing in a cloud. Your readings stay on your phone.

Seven views, one picture of your day
01
02Recovery
How recovered you actually are – from resting heart rate and overnight heart rate variability. The number that tells you whether today can be a hard one.
03Sleep
Sleep phases, duration and trends across weeks. Not a snapshot of one night, but the pattern behind it.
04Strain score
The day's load as a single number – fed by over 236 sports the app can track individually.
05Steps and live heart rate
Step count through the day, and your pulse in real time the moment you start a workout.
06The details
Stress, blood oxygen, resting heart rate, HRV, VO2max and distance – each with a daily curve instead of a single figure.
07Calories and fitness age
Burn across the day, plus your fitness age: your readings translated into a number you can move.
Questions before you buy
When does it ship?
One to two weeks after your payment arrives, depending on where you are. Within Germany and the EU it is usually faster.
Which size do I need?
Measure your wrist circumference. Size L (260 mm) fits 170 – 240 mm and is included, size S (230 mm) fits 140 – 210 mm. If in doubt, add a spare strap in the other size.
How do I pay?
Through Stripe – card, Apple Pay, Google Pay and Klarna. Your payment details never reach our servers, and the invoice arrives by email automatically.
Can I change the strap?
Yes. The tracker pops out of the strap without tools and into another one – in seconds, as often as you like. Spare straps come in five colours and two sizes, and you can add them to your order above.
Is it comfortable to sleep in?
Yes. The band is slim, has no display lighting up at night and no hard edges. That is the point: if you want to measure the night, you have to want to wear the device at night.
How long does the battery really last?
30 to 40 days, depending on how many workouts you record. Every activated training session measures more often and costs battery accordingly.
How long does charging take?
About two hours from empty to full.
Can I wear the band overnight while charging?
No – the band should not be worn while charging. Charge it at a time of day when you do not need readings anyway, for instance in the shower or while cooking.
Is the band waterproof?
Yes, to IP68. It is not made for saunas or deep dives.
Can I shower, swim or go into the sea with it?
Showering and swimming are fine, the housing is protected to IP68. Saunas, steam rooms and diving are excluded, because heat and pressure strain the seals.
Does it measure during training?
Yes. If you start the workout in the app beforehand, the band measures more often and delivers more accurate readings than automatic detection.
How good is the sleep tracking?
Sleep phases are derived from movement and heart rate variability. That works well for observing trends over weeks, but it does not match the accuracy of a sleep laboratory.
Which phones is it compatible with?
The LEEK app is currently available for Android only.
Does it work without a smartphone?
The band records, but without a phone and the app the data cannot be analysed. The app is a requirement.
Are there sport modes?
Yes, more than 236 – from running and cycling through HIIT to sports you will not find in a standard app.
Does it measure stress?
Yes. The app shows a stress score along with its curve across the day.
What happens to my health data?
It stays on your phone. No health data is uploaded to any server – not even ours.
Is the data stored in the cloud?
No. There is no cloud storage and no background synchronisation.
The band will not connect – what can I do?
Restart your phone and the band first – that clears around 95 percent of all connection problems. If it persists: make sure Bluetooth is on and the band has charged for at least 15 minutes. Remove any existing pairing in your phone's Bluetooth settings and start pairing again from inside the app – the band is not paired through the system settings.
The readings look inaccurate – why?
Usually the fit. Do not wear the band directly on the wrist bone or over tattoos – dark ink swallows the measuring light. A finger's width above the bone, snug but not tight, gives the best readings.
Who is the band for?
Both ends: beginners who want to know where they stand, and advanced athletes steering strain and recovery. There is no prerequisite other than wanting to work on your fitness.
How is it different from a smartwatch?
No display, no blinking, no notifications on your wrist – instead an unobtrusive device that lasts for weeks rather than needing a cable every other day.
Can I return it?
Yes, within 30 days and without giving a reason. Send us a short email and return the parcel to the sender address.
