Screenless band development
Screenless health bands and custom wrist-worn devices, with hardware, firmware and companion software developed as one product.
Define the relationships before the build.
Fit & daily use
Agreed data requirements
Firmware & connected experience
What we can work on together
QX TECH designs and manufactures screenless wearable bands for OEM/ODM projects. The C16 is our published screenless health-band reference: approximately 16 g, a zinc-alloy head, TPU strap and daily wellness functions. Custom projects can explore different shapes, materials and interaction approaches; specifications and validation are confirmed separately rather than assumed from C16.
The app becomes part of the product
Removing the screen changes how a user understands the device. Pairing, charge state, synchronization and error recovery need an understandable route through the companion app and any agreed vibration or indicator behavior. The first experience should answer three questions: is it connected, is it recording, and when was the data last synchronized?
A screenless fitness tracker does not have to look like a small smartwatch. Wristband width, fastening, sensor contact and how the device sits during sleep deserve a design discussion. QX TECH has mature experience in screenless-band design and manufacturing; a new project should still be evaluated on its own requirements rather than on a competitor’s appearance.
A real reference, not a universal specification
Use C16 to evaluate an actual device and its documented functions. Its published catalog covers spot/automatic heart rate and SpO₂, sleep and activity. These are general-wellness references, not diagnostic functions. Follow the C16 detail page for the current model specification and discuss the intended use before selecting an algorithm or sensor.
For a custom design, prepare a requirement matrix rather than combining the strongest claims from different products. A smaller enclosure, different strap, additional sensor or more frequent synchronization may change the battery target and engineering work. Ask the development team to identify which characteristics are demonstrated, targeted or still subject to validation.
| Decision | Specify in the brief |
|---|---|
| Wear and fit | Wrist range, closure, materials and overnight use |
| Data and feedback | Metrics, sampling, offline behavior and user feedback |
| Companion software | App branding, synchronization and data ownership |
| Validation | Use conditions, battery test profile and acceptance evidence |
From concept to a repeatable build
Agree the mechanical design, electronics, firmware, app behavior and manufacturing checks together. For a screenless band, functional test coverage should include charging, connection recovery and the data journey into the app, not just a visual inspection of the finished enclosure. The agreed plan should also distinguish prototype findings from production acceptance.
Bring the target market, branding assets, approximate order range and launch priorities to the first conversation. We can discuss catalog-based evaluation or custom development. Tooling, app access, support terms, production quantity and timing are confirmed in the proposal; no minimum order or launch date is implied by this page.
Before we start
Is C16 actually screenless?
Yes. C16, C18 and C22 are the current QX TECH screenless band references, positioned for ultra-slim everyday wear, all-day wellness and temperature context, and sport-oriented active wear. Compare the verified specifications and test conditions for each model.
Can a new band use my own app?
App customization or integration can be scoped. Confirm the device protocol, SDK terms, required data, account ownership and maintenance responsibilities before development.
How should health functions be interpreted?
The published products are described for general-wellness reference. Do not market them as diagnostic or therapeutic devices based on this website.
