Learn how to set up and use the LUCY Smart Cap with your waterdrop Microdrink to track hydration, add flavor, and receive reminders.
Quick answer
Pair the LUCY Smart Cap with your waterdrop bottle and the waterdrop Hydration App to track your water intake, receive drinking reminders, and easily add Microdrink flavor cubes.
Why use a smart cap for flavor infusion?
The LUCY Smart Cap does more than seal your bottle. It connects to the waterdrop Hydration App to log every sip, send gentle reminders when you haven't drunk in a while, and track your daily progress. This turns a simple flavored water habit into a measurable routine.
Because the cap works with any standard waterdrop bottle, you can keep using your favorite carafe or cup while upgrading only the lid. The built-in dispenser holds a Microdrink cube, so adding flavor is as simple as pressing a button.
Step-by-step guide
- Charge and pair the cap: Charge the LUCY Smart Cap fully using the included cable. Open the waterdrop Hydration App on your phone, enable Bluetooth, and follow the in-app pairing instructions. The cap will appear as a new device. A common mistake is skipping the initial charge. A low battery can cause intermittent disconnections, so charge it fully before first use.
- Insert a Microdrink cube: Twist the top of the cap to open the dispenser compartment. Place one Microdrink flavor cube inside, then close the compartment securely. The cap is designed to hold the cube without crushing it. Do not force a cube that seems too large. If it doesn't fit easily, check that you're using a standard Microdrink cube and that the compartment is fully open.
- Attach the cap to your bottle: Screw the LUCY Smart Cap onto a clean, empty waterdrop bottle. Make sure the threads align and the cap is hand-tight. Over-tightening can damage the seal. Always start with a clean bottle rim. Residual liquid or sugar can prevent a proper seal and cause leaks.
- Fill with water and activate flavor: Fill the bottle with cold or room-temperature water. Press the button on the cap once to release the Microdrink cube into the water. Shake gently to dissolve the cube evenly. Avoid using hot water. High temperatures may affect the cube's dissolution rate and could damage the cap's electronics.
- Monitor your intake in the app: The cap automatically logs each sip and syncs with the app. Check the app dashboard to see your daily water intake, set a hydration goal, and view reminders. Adjust the reminder interval in the app settings. If the app doesn't show updated data, ensure Bluetooth is enabled and the cap is within range (about 10 meters). Restart the app if needed.
