The reef tracker that covers the whole tank

A real reef tracker logs more than water tests. Reef Trak tracks parameters, dosing, maintenance, livestock, equipment, photos, and controller data — one history per tank, unlimited tanks.

What a reef tracker should actually track

Most "tracker" apps stop at water tests. A reef generates far more history than that: the dose you adjusted last Tuesday, the pump you cleaned last month, the acro you added in March, the slow alkalinity drift since you changed salt brands. A reef tracker that only stores numbers misses the story.

Water parameters with reef-specific ranges and alerts
Dosing — products, schedules, and every adjustment
Maintenance — water changes, cleanings, recurring tasks
Livestock — fish, corals, inverts, with per-animal history
Equipment — what you run and when it was serviced
Photos — visual history organized by tank and date
Controller data — probe readings imported automatically

Why reef keepers pick Reef Trak as their tracker

Reef Trak is built only for reef and saltwater keeping — not adapted from a freshwater logger. It is free at its core, premium is a one-time lifetime unlock rather than a subscription, and your data exports cleanly so it is never locked in. If you've heard the name as Reef Tracker, ReefTrack, or Reef Track: the app is Reef Trak, at reeftrak.com.
