Tanksmith is the offline reef tank logbook built for serious reefers, the people who test their water at 7 AM, dose 2-part by hand, and obsess over coral growth photos. Everything happens on your device. No account. No cloud sync. No subscription. No ads. No analytics. Your tank's history is yours alone. WHAT YOU GET (FREE) Parameter logging Track Alkalinity, Calcium, Magnesium, Nitrate, Phosphate, Salinity, Temperature, pH, ORP, Ammonia, and Nitrite. Each reading plots against the recommended target band for your tank type: Mixed Reef, SPS-Dominant, LPS-Dominant, Softie, FOWLR, or Quarantine. Test kit & salt batch tracking Record your Salifert, Hanna, Red Sea, Triton, Tropic Marin, and other kits with lot numbers and expiry dates. Track which salt bucket you're using. When a batch is reported bad on the forums, you'll know if you used it. Equipment service tracker Skimmer cleaning, RODI cartridge changes, return pump service, powerhead maintenance. Set intervals, see what's overdue at a glance. Livestock list Record your corals, fish, and inverts with a photo, source, and placement notes. Free tier includes one tank, forty parameter readings, and three livestock entries per tank, plenty to evaluate whether Tanksmith fits the way you keep reef. UNLOCK TANKSMITH PRO ($9.99 ONE-TIME) Multi-tank support Display, frag, and quarantine tanks all in one place. Unlimited parameter readings and livestock No caps. Log every test, track every coral. Dosing intelligence Tanksmith works out your alkalinity and calcium consumption from your reading history and tells you how many milliliters a day to add on top of what you already dose. It covers Randy Recipe #1, BRS 2-Part, ESV B-Ionic, Aquaforest Component 1+/2+, Tropic Marin All-For-Reef, and Red Sea Foundation A/B/C, each using the manufacturer's published strength. When the trend changes, you'll see it. Coral photo timeline + lineage Add dated photos of every coral. Tap two thumbnails to see them side-by-side and watch growth over months.

Tanksmith puts your tank's complete history on the same device that's already in your pocket, and keeps it there. ONE-TIME PURCHASE Pro is $9.99. Forever. No subscription nag screens, no premium tier above Pro, no consumable IAPs. PRIVACY Tanksmith does not collect, transmit, or share any data. There are no third-party SDKs. The only system permission requested is Photos access, and only when you choose to attach a coral photo, which is then stored on your device. Built by reefers, for reefers.
