Water tracking
Water tracking in LifeWell is a one-tap hydration log — every entry records an amount (in millilitres) and an optional context (which container, what activity), and the page rolls those up into a daily total against your goal. The interface is built for speed: tap a glass-size preset, hit "Add", done. No forms, no friction.
This page covers the data model, the goal calculation, reminders, and what the chart and streak counters actually mean.
What you can log
Each entry stores:
| Field | Type | Notes |
|---|---|---|
amount | number | Millilitres (default 250) |
containerType | enum | glass, cup, small_bottle, bottle, large_bottle, sports_bottle, custom |
customContainerName | string (optional) | Used when containerType is custom |
loggedAt | timestamp | Defaults to "now" unless you back-date |
activity | enum (optional) | exercise, meal, wakeup, sleep, work, other |
temperature | enum (optional) | cold, room, warm |
withAdditive | string (optional) | e.g. "lemon", "mint" |
notes | string (optional) | Anything you want to remember |
Only amount and loggedAt are required. Most users tap a preset and skip every optional field.
Container presets
The standard presets and their default volumes:
| Preset | Volume |
|---|---|
| Cup | 200 ml |
| Glass | 250 ml |
| Small bottle | 330 ml |
| Bottle | 500 ml |
| Large bottle | 750 ml |
| Sports bottle | 1000 ml |
| Custom | Any amount you specify |
Your default glass size for the one-tap "Add" button is configurable under Preferences → Glass size. Most users pick 250 ml or 500 ml and rarely touch it again.
Daily goal
The daily goal is a millilitre target you're aiming for each calendar day (resetting at midnight in your selected time zone — see Preferences → Time zone).
You can:
- Set a fixed goal — default is 2000 ml, choose anywhere from 500 to 5000 ml.
- Let it auto-calculate from your profile inputs.
Auto-calculation formula
When you turn on auto-calculation, the goal is computed in millilitres from your inputs:
base = weightKg × 30 # ~30 ml per kg
base × activityMultiplier # see table below
base × climateMultiplier # see table below
+ 300 ml if "active phase" is on
+ 700 ml if "breastfeeding" is on
round down to the nearest 100 ml
| Activity level | Multiplier |
|---|---|
| Sedentary | 1.00 |
| Light | 1.10 |
| Moderate | 1.20 |
| Active | 1.30 |
| Very active | 1.50 |
| Climate | Multiplier |
|---|---|
| Cold | 0.95 |
| Temperate | 1.00 |
| Hot | 1.20 |
For example, a 70-kg moderately active person in a temperate climate gets 70 × 30 × 1.20 = 2520 → rounded to 2500 ml. The same person breastfeeding in a hot climate gets 70 × 30 × 1.20 × 1.20 + 700 = 3724 → 3700 ml.
This is a heuristic, not a clinical recommendation. The Institute of Medicine's general adequate-intake reference is ~2.7 L/day for women and ~3.7 L/day for men including water from food, with significant inter-individual variation. The LifeWell formula tries to approximate beverage-water target. Adjust to taste.
Manual override
You can override the calculated goal with a fixed customAdjustmentMl (e.g. "always add 500 ml on training days"). Or just turn auto-calc off and pick a goal manually.
The progress ring and quick-add
The water page's centrepiece is a progress ring that fills as you log entries against the goal. To its right are three quick-add buttons — 250 / 500 / 750 — plus a custom-amount field. Pressing one of them sets the amount; the Add button below logs it.
The page also exposes the most recent 10 entries in a scrollable list, each with its amount, unit, and timestamp. Tap an entry to edit or delete it.
Reminders
Water reminders are off by default. To turn them on, go to Reminders → Water and pick:
- Start time (default 07:00) — earliest ping of the day.
- End time (default 21:00) — latest ping of the day.
- Interval (default 60 minutes) — how often during the window.
Reminders fire as push notifications on mobile (if installed), and as in-app banners on web. Snoozed reminders re-fire after the snooze duration (default 15 min).
If you have the LifeWell browser extension installed, water reminders can route to the extension's wellness-reminder system instead of the web tab — handy for users who keep many tabs open.
Streaks and achievements
Hitting your daily goal for two or more consecutive days starts a streak. The streak counter lives in the page header and on the dashboard. Missing a day breaks the streak — there is no streak-freeze yet (planned).
Streak milestones (7-day, 30-day, 100-day) trigger achievement unlocks under Achievements. These are cosmetic — they don't unlock features.
Hydration insights
For Pro accounts (when monetisation lands), the Insights subview computes weekly / monthly / yearly aggregates: average daily intake, best day, most-active hour for logging, longest streak. The free tier shows the daily ring and a 7-day mini-chart only.
Honest framing
Water tracking in LifeWell is:
- A behaviour-shaping tool, not a clinical recommendation. The "30 ml per kg" formula is a useful starting point, not a medical prescription.
- Beverage-focused. Water from food (which the Institute of Medicine counts) is not estimated here.
- Self-reported. Mis-logged amounts produce wrong totals.
- Browser-blind. If you sip from a bottle at your desk and forget to tap, LifeWell will never know.
If you have a medical condition that limits or requires a specific fluid intake (kidney disease, heart failure, etc.), follow your clinician's guidance — not LifeWell's default goal.
Frequently asked
My phone is offline at the gym — will my logs save? Yes. Entries write to local Capacitor Preferences first and sync to Firestore as soon as connectivity returns. See Offline-first design.
Can I log non-water (coffee, tea, juice)?
Yes — set containerType to custom and put the beverage name in customContainerName. There's no separate caffeine or sugar tracking here; this surface counts hydration volume.
My streak broke because I was travelling and the timezone shifted. Streaks compute against your selected time zone, not your device's. If you're hopping zones, set Preferences → Time zone to a fixed home zone so days roll over consistently.
Can I see my historical water entries on a calendar? The insights tab includes a calendar heatmap (per-day fill levels) on the planned Pro tier. The free tier shows the 7-day mini-chart.
Does the browser extension count clicks I make on the web app? No — the extension has its own quick-log button that writes to the same Firestore collection. Both surfaces show the same total.
