Turn every water test into one clear next step — safe, watch, or act now. Free ammonia from pH & temp, cycle help, and a shareable tank report. On-device, no ads. FishVitals turns your water test results into one clear next step — so you never second-guess your aquarium again. Log pH, ammonia, nitrite, nitrate, GH, KH and temperature, and FishVitals instantly shows whether your tank is safe (green), needs attention (yellow), or needs action now (red) — with exactly ONE recommended water action. No guesswork, no conflicting forum advice. WHY FISHKEEPERS LOVE IT • Clear red / yellow / green safety read on every test • One next water action — never a wall of numbers • Free ammonia (NH3) calculated from pH & temperature, not just the raw test value — the way toxicity actually works • Nitrogen-cycle companion that guides you through a new tank • Care reminders so water changes and tests never slip • Shareable "Tank Help Report" for your local fish store or online community • Trend charts for every parameter BUILT RIGHT • 100% on-device — no account, no ads, no tracking • Works fully offline • Freshwater-first and beginner-friendly FishVitals is a water-test log and educational tool, not veterinary or medical advice. Pro unlocks full history, all parameter trends, and the complete Tank Help Report. FishVitals Pro is $1.99/month or $8.99/year (prices may vary by region). The subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings.
