Reminders
The tone is synthesised with the Web Audio API — no sound file is downloaded, and nothing leaves your device.
Targets here are general hydration guidance for healthy adults. People with kidney, liver or heart conditions, or on fluid-restricting medication, should follow their clinician's advice instead.
About this tool
This tracker builds a daily target from a body-weight baseline plus real adjustments for training duration, climate, caffeine and alcohol, then keeps a per-date drink log so the seven-day chart reflects genuine history rather than a session total. Drinks are added with quick buttons or any custom volume, and the reminder uses a synthesised Web Audio tone with an opt-in browser notification. Every log entry is stored in your browser's localStorage keyed by calendar date; nothing is uploaded and there is no account.
