Tankive: Aquarium Tracker
Water Tests & Shared Care
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Know what changed, what is due, and who did it. Keep private aquarium records offline, then share a tank with a partner or caretaker through iCloud.
Keep every aquarium’s water tests, care, livestock, and changes in one clear record.
Tankive is built for freshwater, planted, shrimp, saltwater, and reef aquariums. Log routine care without a network connection, review parameter trends, and understand what changed over time.
WATER TESTS AND TRENDS
• Record temperature, pH, ammonia, nitrite, nitrate, GH, KH, phosphate, salinity, and custom parameters
• Set aquarium-specific target and warning ranges
• Review parameter history and clear trend charts
• Compare recent measurements with aquarium events
CARE WITHOUT GUESSWORK
• Schedule feeding, water changes, tests, fertilizer, dosing, filter care, and custom tasks
• Receive optional reminders for recurring care
• Quickly record feeding, water changes, doses, and observations
• Keep completed care in the aquarium’s permanent timeline
A COMPLETE AQUARIUM HISTORY
• Track livestock, plants, equipment, breeding, expenses, observations, and photos
• Review water tests, care, additions, moves, notes, and milestones in one dated timeline
• Compare photos and aquarium changes over time
• Search across tanks, livestock, equipment, notes, and care tasks
SHARE CARE PRIVATELY
• Share an aquarium through Apple iCloud
• Give a partner or caretaker read-only or edit access
• Prepare caretaker plans with dates, instructions, and tasks
• Let invited caretakers use the relevant shared-tank features without purchasing a subscription
• No Tankive account is required
LOCAL FIRST AND PRIVATE BY DESIGN
Routine logging remains available without a network connection because records are saved locally first. Optional iCloud sync and sharing use your private or shared Apple CloudKit database.
Tankive has no advertising, tracking SDK, third-party analytics, or developer-operated aquarium-data backend.
Export a help summary, measurement and timeline CSV files, or a complete JSON record. Existing records remain readable and exportable if a subscription ends.
FREE AND PRO
The free version supports one aquarium and the main water-test, record, and care tools.
Tankive Pro is an optional auto-renewable monthly or yearly subscription. It unlocks more than one owner-created aquarium, owner sharing controls, What Changed comparison, caretaker plans, and all calculators.
Payment is charged to your Apple Account. Subscriptions renew automatically unless canceled at least 24 hours before the current subscription period ends. You can manage or cancel your subscription in your Apple Account settings.
