About this app

Manage every fish tank you own from one aquarium app — water parameters, livestock, equipment and maintenance, kept in a single timestamped history you can trust.

TankSnap is an aquarium log and tank tracker built around your camera. Point it at a test strip and your pH, ammonia, nitrite and nitrate readings are recorded in seconds. Photograph a new fish and it is identified and filed against the right tank. Nothing has to be typed, so the log actually gets kept — and a log that gets kept is the one that warns you before a problem costs you livestock.


WATER PARAMETERS, TRACKED PROPERLY

Every water test becomes a data point instead of a note you lose. TankSnap records pH, ammonia, nitrite, nitrate, phosphate, GH, KH and temperature, plus any custom parameter you want to add, so slow drift stays visible while it is still cheap to fix.

• Scan test strips with the camera, or enter readings by hand if you prefer
• See each parameter's history per fish tank, against your own safe ranges
• Follow a new tank through the nitrogen cycle — ammonia and nitrite rise and clear while nitrate climbs
• Spot the conditions behind an algae bloom before the algae takes hold
• Get reminded when a tank is overdue for testing or a water change


WHAT YOU CAN LOG

• Water tests — every parameter, charted over time
• Water changes, filter cleans and the rest of your maintenance routine
• Medication and fertilizer doses, calculated from each tank's real volume
• Livestock — betta, goldfish, cichlid, tetra, shrimp, snails, coral and more
• Aquatic plants and the fertilizer routine that keeps them growing
• Equipment — filters, heaters, lights, pumps — with install dates and service history
• Consumables, so you know what you have before you reorder


KEY FEATURES

• Multi-Tank Management: freshwater, planted, saltwater, reef, shrimp and breeding tanks side by side
• Water Test Scanner: read a strip with your camera, no manual entry
• Health Insights: AI analysis of your own tank's history, flagging parameter drift before livestock are at risk
• Dose Calculator: exact treatment amounts for your volume — safe for reef, planted and freshwater setups
• Smart Reminders: per-tank schedules for testing and water changes
• AI Livestock ID: identify freshwater fish, marine species, coral, shrimp and aquatic plants from a photo
• Correction History: edited entries keep a full audit trail, so the record stays trustworthy
• Full Data Export: your history is yours — take it with you whenever you want


NO ACCOUNT, NO ADS

TankSnap never asks for an email address, a password or a social login. There is no account to create and nothing to sign in to — your aquariums live on your device. There are no ads anywhere in the app.


WHO IT IS FOR

Whether you manage a single planted community tank, a shrimp breeding project, a reef, or a fishroom with dozens of fish tanks, TankSnap scales to it. It is for anyone who has lost a fish to something that changed slowly and got noticed too late.

TankSnap is the aquarium app that keeps the record for you, so managing your fish tank stops being the thing you fall behind on. Start keeping the aquarium log you have been meaning to keep.
Scan test strips, ID fish & track water parameters. Aquarium log & reminders.
