Calm Hydration Tracking
Build a better hydration routine across phone, widget, and watch.
WaterFlow is for people who want faster logging, cleaner reminders, and progress they can read at a glance. The core experience stays local-first, account-free, and focused on routine instead of noise.
Local-first
Core hydration data stays on your device.
Premium unlocks
Widget, watch, analytics, achievements, and device transfer.
Yearly views, averages, streaks, and momentum in a cleaner format.
Log from your wrist or home screen when the app itself should stay in the background.
Why it feels better
A hydration app that respects attention.
The value is in the full loop: quick logging, useful reminders, visible progress, and access from the right surface at the right time.
Log fast, stay moving
Custom cup sizes and a home screen built around the action users repeat every day.
Keep reminders useful
Quiet hours, stop-on-goal behavior, and rhythm-aware notifications reduce reminder fatigue.
Read progress clearly
Statistics and achievements make hydration feel like a visible routine instead of a buried history list.
Product Surfaces
Premium utility, not decorative features.
WaterFlow becomes more useful as it spreads across the surfaces people already use during the day.
Home Screen
The main screen is built for repeat use
Daily progress, cup choices, and reminders stay visually calm while keeping the main action immediate.
Statistics
Long-term consistency becomes visible
Monthly and yearly views make streaks, off days, and realistic averages easier to spot.
Achievements
Motivation stays inside the product
Achievement tracking adds momentum without turning hydration into a noisy social layer.
Widget
Progress that stays visible from the home screen
The widget makes hydration glanceable without forcing another full app open.
Watch
Quick hydration check-ins on your wrist
Wear OS support extends the habit loop with quick-add actions and mirrored reminders.
What Premium Unlocks
Usefulness first, access second.
Premium is centered on daily convenience: better surfaces, clearer visibility, and trusted transfer between devices.
Phone, widget, and watch
Premium expands the hydration loop to the surfaces people naturally return to.
Statistics and achievements
Progress stays motivating because it becomes legible over time.
Trusted device transfer
Continuity comes from controlled transfer tools instead of an account-based sync system.
