User Reviews

Pocket Marine is praised for its comprehensive logging and databases for reef tanks, including multi-tank tracking and a modern UI. However, users report stability and data management issues, poor syncing/backups, unit and parameter customization problems, and a lack of export or cloud backup features. Addressing these would greatly improve reliability and cross-device usability while preserving its strong logging capabilities.

Pros

Comprehensive tracking of water parameters, tests, and tank diary across multiple tanks.
Modern, user-friendly UI/design that many users compare favorably to other reef apps.
Robust livestock data management and reference content for reef species.
Useful features like test diary and graphs to visualize trends.
Multi-tank management support, making it suitable for hobbyists with several tanks.

Cons

Cross-device data sync/backup is missing or unreliable, risking data loss when switching devices.
Stability issues: crashes during setup or in specific sections; reports of data loss.
Unit/measurement support is incomplete or confusing (liters/gallons, Celsius/Fahrenheit) and hard to customize.
Default parameters are limited to nine visible options and are not easily customizable.
No straightforward data export or cloud account to back up or transfer data between devices.
