Aqua Stable

AquaStable helps freshwater and saltwater aquarium keepers track water quality and keep their tanks stable.

Record your parameters, watch trends on real-time charts, scan test strips with your camera, and calculate dosing and water changes — all in one app.

KEY FEATURES
• Water-parameter logging — pH, temperature, NO₂, NO₃, GH, KH, Ca, Mg, salinity, Cl₂, plus your own custom parameters
• Real-time line charts to spot trends at a glance
• Test-strip scanning — point your camera at a Tetra 6-in-1 (freshwater) or 5-in-1 (saltwater) strip; automatic strip detection and white-balance correction read the colors for you, and the app learns from your corrections to improve accuracy over time
• Calculators — water-change volume, tank volume, and water-change simulation (free); KH, Ca, and specific-gravity dosing (Pro)
• Multi-tank management — handle several tanks with freshwater/saltwater types
• Backup & restore your data (Pro)
• English and Japanese support
• Reference ranges for freshwater and saltwater

FREE & PRO
The free version includes one tank, up to 30 logs, and the core calculators. Upgrade to Pro for unlimited tanks, unlimited logs, custom parameters, the KH/Ca/specific-gravity calculators, and backup & restore.
