BEFORE YOU ORDER
Questions people ask
How does the sedentary reminder work?
Pick an interval in the app; when your wrist logs no meaningful movement for that stretch, the band vibrates until you get up.
Can I shower with it?
IP68 covers splashes, sweat and everyday water contact; hot showers and saunas shorten any tracker’s life.
What languages does the app support?
A wide set including English, German, French, Spanish, Japanese, Korean and Vietnamese.
How does the multi-buy discount work?
It comes off on its own at checkout, with no code to type. Two items anywhere in your basket take 10% off, three take 15%, four take 20%. They do not have to be the same product.
When will it arrive?
Orders are dispatched within 1–2 business days and tracking is emailed as soon as the parcel leaves. If it is not for you, unused items can be returned within 30 days — email us first for the return address.
