MYRYDER C4Plus Fitness Band

No. The C4Plus works straight out of the box — no app to download, nothing to pair. A BT 5.4 chipset is on board the platform, but the band is fully functional as a standalone device, which is exactly what makes it popular for giveaways and promotions.

Up to 40 days of normal wear on a single charge. The main unit pops out of the silicone band and plugs directly into any USB-A port — no charging cable is needed.

It is daily waterproof: splashes, rain and hand-washing are fine. It is not rated for swimming, diving or hot showers.

Accurate 3D step counting with steps, distance and calories on screen, plus time display and a silent vibrating alarm. It deliberately has no heart-rate or sleep sensors — if you need those, see the C1Plus, C2Plus or C3Plus in the same category.

Black, sky blue, white and pink silicone bands. OEM/ODM customisation of strap colours, packaging and logo placement starts from 500 pcs per model.

Anyone who wants a watch-like time and activity display without a phone in the loop: retail promotions, corporate giveaways, kids and seniors, and entry-level private-label programmes.

Our standard OEM/ODM programme starts from 500 pcs per model, with mixed colourways available within one order.

They share the same app-free LED platform — 17.2 mm band, 3D step counting, silent vibration alarm, 40-day battery and USB direct charging. The C4Plus is positioned around its four colourways (black, sky blue, white, pink); check each product's spec table for the fine differences.
