iOS water tracker

Drink water. Earn caps. Keep the streak alive.

Capdrop is a local-first water tracker made for visual people: one tap, a filling bottle, useful reminders, widgets, and a reward loop that stays out of the way.

What it is

A habit app that makes the next action obvious.

Capdrop keeps the important parts on one screen: today's amount, the current bottle fill, quick log buttons, caps earned, and a visible streak. It avoids accounts, feeds, and dashboard noise.

Core loop

Built around one-tap follow-through.

01

Animated bottle

Progress is shown as water, not just a number. Completed bottles stay visible as daily momentum.

02

Cap rewards

Each 500 mL earns a bottle cap, giving the habit a small collectible reward without adding complexity.

03

Widgets

Small, medium, large, and Lock Screen widgets show progress and let common amounts be logged quickly.

04

Local history

Weekly bars, streaks, best days, and a contribution-style map keep history visual and readable.

Use cases

For days when opening an app is already too much.

Home screen

Log common amounts without scrolling or choosing from a long list.

Notification actions

Respond to reminders with preset amounts or snooze when now is not the time.

Widgets

Put progress where you already look and avoid the friction of app switching.

Visual identity

Five alternate icons, one reward system.

Capdrop includes selectable app icons so the home screen can feel like a personal object instead of another utility square.

FAQ

Plain answers.

Does Capdrop need an account?

No. It is designed to work locally on the device.

Does it send hydration data to a server?

No backend is used by the native app. Export creates a local JSON file only when requested.

Can widgets animate like the app?

No. Widgets use lightweight snapshots to respect iOS battery and WidgetKit limits.

Make water impossible to ignore.
