ReefScribe

ReefScribe is a mobile-first, offline-first aquarium log app for reef, saltwater, and freshwater tanks.

Designed with a clean, intuitive interface, ReefScribe helps you keep a complete aquarium log in one place:
• Log water parameters with timestamps, custom ranges, and charts
• Record water changes and maintenance (with notes)
• Track fish, coral, and invertebrates with photos and lifecycle history
• Add notes for observations, issues, and dosing
• Set reminders for testing, water changes, and routine tasks
• Export and restore full backups (database + photos)

ReefScribe works fully offline. Your aquarium data stays on your device, with optional local backups you control.

A free version is available with reasonable limits. A one-time Pro upgrade removes limits and unlocks the full experience.
