Aqumi is a native macOS hydration tracker that lives in the menu bar and calculates a personalized daily water intake goal from your weight, age, sex, and activity level. A droplet icon in the menu bar fills progressively toward the daily goal as you log drinks. ($4.99 lifetime license)
Logging a drink takes a single tap: users select from preset container sizes or enter a custom amount. Global hotkeys (⌘⇧W to open the popover, ⌘⇧L for quick-logging) let you record intake without reaching for the mouse. Reminder cadence is configurable, with quiet hours to suppress notifications outside working hours and automatic respect for macOS Do Not Disturb status. Notifications include one-tap log, snooze, and mute actions without opening the app.
The app tracks streaks, displays weekly bar charts, and shows a 30-day trend — enough history to identify patterns without requiring a separate health analytics platform. All data stays on-device; no account, cloud sync, or subscription is involved.
System requirements: macOS 14 Sonoma or later. Compatible with Apple Silicon and Intel Macs. One license covers up to 3 Macs.
Pricing: $4.99 one-time lifetime license. Includes a 14-day free trial with full functionality; no credit card required.
Limitations: Requires macOS 14 Sonoma, excluding users on older macOS versions. No iPhone or Apple Watch companion app, so tracking is limited to time spent at the Mac. Hydration data cannot be exported to Apple Health.
Alternatives: WaterMinder (iOS-first with Apple Health integration and Apple Watch support), Fluid (simpler hydration tracker without goal calculation), macOS Reminders (manual reminders with no intake logging).
Suitable for users who spend most of their workday at a Mac and want a low-friction way to build consistent hydration habits without installing a subscription app.
