What is Koiven?

Koiven is a cozy hydration tracker for Android. Log a drink and your on-screen aquarium fills while your pet fish, Zenna, swims. It includes a personalized daily goal, streaks, weekly progress dots, and free custom drinks, all wrapped in a deliberately calm interface. Koiven runs fully offline with no account and no email; your data stays on your device and backups are your own Google Drive snapshot. Free to use, with an optional Pro tier that adds more fish and themes, more drink slots, and removes ads. iOS planned for a future release.
