What it brings you
Weighed water tracking
HX711 precision load cell automatically logs every sip — no manual check-ins.
Grip wellness sensing
Hold the grip to measure heart rate / SpO2 (PPG); an infrared sensor logs body temperature as daily wellness reference.
Fingerprint family mode
AS608 fingerprint sensor distinguishes family members — each with their own hydration goal and data.
Voice + LED reminders
Four voice prompts (drink, goal reached, hot water, low battery) and three breathing LEDs for status.
Magnetic charging · IPX5
Sealed bottom with no ports, magnetic pogo-pin charging, IPX5 water resistance.
30-day-class battery
Low-power architecture with event-driven power design targets a 30-day-class battery life.
Transparent R&D progress
The percentage is assessed from completed milestones across the whole development plan, and updated as development moves forward.

Back the Smart Cup crowdfunding
Early access · Founder pricing
Crowdfunding backers get priority access to engineering samples and founder pricing, plus first updates on mass-production schedules.
Co-development · Custom
Enterprises can co-develop on any active project: custom sensors, enclosures, apps and cloud platforms — sharing the R&D outcome.
Channel · Industrial partners
Distributors, system integrators and industrial investors are invited to participate via crowdfunding or strategic partnership.
What stage is the Smart Cup at?
Can the heart rate / SpO2 data be used for medical diagnosis?
We put risks on the table
Crowdfunding means sharing development uncertainty with us — please read these before backing.
- Pilot-run yield: the production PCB is about to go to pilot fabrication; first batches may have assembly adjustments. Triple-verified DRC and pilot validation precede shipment, with full refunds before shipping.
- Sealing process: waterproofing depends on sealing and potting quality — full-unit water tests run before mass production.
- Data compliance: heart rate, SpO2 and temperature data are wellness reference only; no medical claims.
- Patent uncertainty: two patents are pending; outcomes don't affect product functionality.
