02 · CORE FUNCTIONS
Quietly intelligent.
Automatic when it should be. Transparent when it matters.Automatic intake logging
Calculates and records every drink from the weight difference before and after you lift the cup.
Event recognition
Separates drinking, refilling, and simply moving the cup so your timeline stays meaningful.
Any Cup Mode
Works with cups of different sizes and weights through swappable silicone base sleeves and cup profiles.
Automatic tare
Subtracts the cup and Base weight so the app tracks the water, not the container.
Measurement Confidence
Shows how trustworthy each reading is based on stability, calibration, battery, and surface conditions.
Hydration timeline
Creates a continuous record of drinks, refills, and cup movement throughout the day.
Hydration Pace Coach
Analyzes drinking speed and timing distribution to help you build a steadier rhythm.
Smart Reminder
Reminds you only when the timing makes sense, instead of sending repetitive fixed alarms.
Continuous context tracking
Keeps home, office, and travel hydration activity together in one consistent record.
Device health
Displays battery level, Bluetooth signal, calibration state, and measurement readiness.
03 · HOW TO USE
Set it once.
Then just drink.
- 01
Install the Smart Base
Fit the correct silicone base sleeve around the bottom of the cup. The cup base must sit flat against the internal pressure-sensing surface, and the Base should be only slightly wider than the cup.
- 02
Use a stable surface
For first-time setup, place the empty cup and attached Base on a hard, flat, level table.
- 03
Connect with Bluetooth
Open the app, tap “Connect,” and select the nearby LDW Smart Base.
- 04
Create a cup profile
Choose or create a cup type and enter its capacity, such as 12 oz, 24 oz, or 40 oz.
- 05
Calibrate the empty cup
Keep the empty cup still and tap “Calibrate / Auto Tare.” The system records the starting weight of the cup and Base.
- 06
Refill and let it settle
Add water, return the cup to the table, and wait about 1–2 seconds. The app identifies the event as “Refilled.”
- 07
Drink normally
Lift the cup, drink, and place it back on the stable surface. The system calculates intake from the before-and-after weight difference.
- 08

THE CORE PRODUCT LOGIC
Fit it to the cup → connect with Bluetooth → calibrate the empty cup → drink normally → let every return to the table calculate itself.
04 · IMPORTANT NOTES
For the most
reliable reading.
LDW measures physical weight changes. Surface stability, correct fit, and calibration directly affect confidence.- 01
Place the Base on a hard, flat surface. Beds, sofas, and thick tablecloths reduce measurement accuracy.
- 02
Allow the cup to remain still briefly after placing it down. Data captured while the cup is shaking should not be logged immediately.
- 03
Recalibrate whenever you change the cup or silicone sleeve.
- 04
Do not let the cup catch on the edge of the sleeve. The full cup bottom must contact the sensing surface.
- 05
Use the correct silicone sleeve when switching between significantly different cup-bottom sizes.
- 06
Until waterproof certification is complete, never immerse the Base or place it in a dishwasher.
- 07
Remove the Base before washing the cup. Clean the device with a slightly damp, soft cloth.
- 08
Keep water away from the charging port, seams, and button areas.
- 09
Do not use the Base as a cup handle. Always lift the cup by its body.
- 10
Do not exceed the sensor’s rated load. Compatibility with the largest Stanley-style cups should use a 3–5 kg full-scale measurement range.
- 11
Before using hot drinks, verify the temperature tolerance of the silicone and internal electronics.
- 12
Power the device off and keep it dry during long periods of storage.
- 13
Low battery, a tilted surface, or an unstable cup should lower Measurement Confidence. The product is not a precision medical device.
