Water Buddy: Drink Reminder

Water Buddy is a lightweight, playful hydration tracker for everyday water rhythm.

Quickly log a cup or a sip, or backfill a drink for today or a previous day. Starting with 0.2.0, every cup leaves its own record. You can review the time, amount, cup, and source, then edit or delete a specific record if something was entered incorrectly.

Water Buddy is not built around complex health dashboards or streak pressure. It acts more like a quiet companion: reminding you to drink, showing your daily rhythm, and saving small moments of self-care.

Key features:

- Per-cup hydration records: review, backfill, edit, and delete individual drinks.
- Custom cups: common default sizes plus 24 playful cartoon cup styles.
- Week, month, and year history: trends aggregated from real records.
- Flexible reminders: choose interval or fixed-time schedules, active weekdays, and quiet hours. Use gentle notifications, or choose system alarm-style strong reminders on supported systems.
- Lightweight rewards: water-mark, half-cup, and full-cup stamps celebrate progress without pressure.
- Lasting milestones and sharing: collect total-cup and goal-day milestones, then create a keepsake card locally when you choose to share.
- Widgets and Live Activity: keep today’s progress on the Home Screen, Lock Screen, and Live Activities.
- Shortcuts and system controls: log or check hydration through Siri, Shortcuts, Home Screen quick actions, and on iOS 18, Control Center, Lock Screen controls, and the Action Button on supported devices.
- Apple Watch: check progress and log water from your wrist.
- Languages and themes: Chinese, English, Japanese, Korean, and multiple cartoon themes.
- Optional iCloud sync: sync per-cup records, cups, daily stamps, and milestones through your private CloudKit database while local logging remains available offline.
- Privacy-first: no developer account required; hydration facts are not sent to developer servers or Firebase.
- Support the developer: optional coffee or milk tea purchases help support continued updates, without unlocking features or changing the core experience.

Water Buddy is for people who want an easy way to remember water, enjoy cute widgets, and prefer calm progress over complicated metrics.
