Aquadex : Log

AquariumLog is a professional aquarium parameter management system designed for hobbyists who treat fishkeeping as a science.

PARAMETER TRACKING
• 6-parameter water test log: pH, NH3 (ammonia), NO2 (nitrite), NO3 (nitrate), temperature, salinity
• Threshold-based status engine — automatic safe / warning / danger classification per parameter
• Per-tank historical record with reverse-chronological access

ANALYTICS
• pH trend chart with ideal-line overlay (7.0 reference)
• Nitrogen cycle chart — ammonia, nitrite, nitrate plotted together
• Temperature chart with ideal range (78°F)
• Days-running counter, test count, care log count, fish census

CARE WORKFLOW
9 care types: water change (with gallons logged), feeding (with food type), filter cleaning, glass cleaning, gravel vacuum, equipment check, algae removal, plant trimming, other.

TANK & LIVESTOCK MANAGEMENT
• 7 tank type presets — freshwater, saltwater, brackish, planted, betta, goldfish, cichlid
• Capacity tracking in gallons
• Fish & invertebrate inventory with name, species, date added, alive/deceased status
• Per-tank notes

DATA OWNERSHIP
• Built on SwiftData (Apple native persistence)
• 100% on-device storage — no cloud sync, no account, no telemetry
• One-tap JSON export of all tanks, tests, logs and livestock
• Zero network calls, zero third-party SDKs

PLATFORM
• iOS 17+ / iPhone-only
• Native SwiftUI, optimized for the latest iPhones
• Built-in iOS Charts framework

If you keep precise records, run controlled water changes, and want to see your nitrogen cycle in graphs — this is your tool.
