Water Tracker for Dummies

The water tracker that turns your day into a simple routine.

Tap a drink size and Water Tracker for Dummies handles the math. Version 1.4.2 adds a Routine Coach that shows whether your day is ahead, steady, behind, or complete, then suggests the next practical sip window from your goal and reminder settings. Past-day entry, catch-up planning, and long-term trends are still built in. Everything stays on your device.

Routine Coach (new in 1.4.2)

See whether today is ahead, steady, behind, or complete. The app calculates your expected pace across your wake window, remaining ounces, open reminder windows, and next practical sip size.

Past-day entry (new in 1.4)

Forgot to log a drink yesterday? Open any day in the Last 7 Days list and tap "Add a missed drink." Log a quick-tap size, a custom amount, or any catalog beverage — the day's total updates instantly.

Catch-Up Advisor (new in 1.4)

When you're behind pace, a new card shows exactly how many ounces remain, how many ~8 oz sips to take, and how often — so you can still hit your goal before your sleep window closes.

Consecutive goal weeks (new in 1.4)

All-Time Insights now shows how many full calendar weeks in a row your daily average met or beat your goal — alongside your existing day streak and personal bests.

Color note

Tap the closest 8-shade color and save it as a personal wellness note. The app uses observation-based labels and does not diagnose, treat, monitor, or replace qualified guidance.

Quick Add

Log a custom amount of water in seconds without opening the beverage catalog. One tap opens a sheet with common shortcuts (4–20 oz or mL/cups equivalents) or a number field for any amount.

All-Time Insights

See your personal best single day, all-time longest streak, overall daily average, goal hit rate, and consecutive goal weeks. A day-of-week chart shows which day you tend to hydrate best, across up to 400 stored days.

Tap any drink

Six quick drink-size buttons plus a bundled catalog of 45+ beverages, from water and coffee to milk, sports drinks, and more.

On-device reminders

Gentle hydration nudges across your day, scheduled locally on your iPhone. No server and no account required.

Goal calculator

Get a recommended daily target from your body weight, activity level, and climate, with the formula and sources shown in the app.

Beverage hydration index

Optionally weight each drink by how much fluid your body tends to retain, using a catalog based on a peer-reviewed study (Maughan et al., AJCN 2016).

Charts & calendar

7-day, 30-day, and 12-month trend charts plus a goal-met calendar heatmap, backed by long-term local history.

oz / mL / cups

Read and log in the unit you prefer. Totals, goals, container sizes, and Quick Add shortcuts all follow your choice.

Edit & export

Delete any individual entry from today or a past day, add missed entries to past days, and export a JSON or CSV backup you can re-import.

Local and private

No account, no cloud sync, no ads, and no analytics. Your data never leaves your device unless you export it yourself.

Water Tracker for Dummies provides general wellness information only. It is not medical advice and does not diagnose, treat, or monitor any condition. The goal calculator, hydration index, routine coach, catch-up advisor, and color note are educational estimates based on published guidelines (NASM, Cleveland Clinic, NHS, and the beverage hydration index study by Maughan et al., American Journal of Clinical Nutrition, 2016). Use qualified guidance for personal health concerns.
