HydraTag

About this app

Make every sip easy to remember. HydraTag keeps your daily water log simple, with a clear progress view and optional NFC sticker logging.

YOUR DAY AT A GLANCE
Set your own daily goal and watch the water droplet fill as you log drinks. Choose a quick amount or enter exactly how much you drank. Undo a recent entry when you need to.

TAP YOUR STICKER
Use a compatible NFC phone and a writable, NDEF-formatted HydraTag sticker to save your chosen amount per tap. You can read and update the sticker from the app. A sticker records a preset amount; it does not measure your bottle or detect how much you drink. Manual logging works without NFC.

SEE YOUR HABITS
Review your entries, daily totals, and progress over 7 days, 30 days, or a year. Remove an incorrect drink from your history.

MAKE IT YOURS
Choose millilitres or US fluid ounces, light or dark appearance, and optional reminders.

PRIVATE BY DEFAULT
Your water history and preferences stay on your device. No account is required. HydraTag does not sync your drinking history to a cloud account.

HydraTag is for general wellness. It is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. For medical advice, speak with a qualified healthcare professional.
