Reefr learns your tank's own history and quietly flags trouble before it becomes a crisis — with Nemo, a calm companion for your first year of reef-keeping. Most new reef-keepers quit in their first year — usually somewhere in the "ugly stage," when algae blooms, parameters swing, and every forum answer disagrees. Reefr exists to walk you through that valley. Reefr is a first-year reef companion that learns YOUR tank — not generic advice, but early warnings drawn from your own history. LOG IN SECONDS Track the vitals that matter — temperature, salinity, alkalinity, pH, nutrients — with fast, friendly logging. Works fully offline; syncs when you're back. EARLY WARNINGS FROM YOUR OWN TRENDS Stability beats perfect numbers. Reefr watches your history for the swings that actually harm livestock and flags them gently — calm and clear, never panic. MEET NEMO Nemo is a calm clownfish companion who knows your tank's whole story — every reading, every photo, every past wobble. Ask anything in plain language and get one conservative next step. Never a wall of options. GROWS WITH YOUR TANK A new tank starts simple. Features unlock as your reef matures and you're ready — through cycling, the ugly stage, stabilising, and thriving. YOUR PHOTO CATALOGUE Snap your fish, corals and gear; Nemo can identify species from your photos — only when you ask. Watch your reef's story build over time. LEARN AS YOU GO Short, vetted articles surface exactly when they're relevant to what your tank is doing — not a firehose of content. PRIVATE BY DESIGN Your readings, photos and notes live in your private account — never sold, never used for ads, never mixed into analytics. AI sees your data only when you explicitly ask. Also on the web: sign in to the Reefr web companion for big-screen trends, bulk logging and your full history. Reefr is free while in early access. Your tank, remembered
