About this app
Shoal & Stem is the freshwater aquarium journal hobbyists actually use — and it's 100% free. No subscription, ever.
Whether you're keeping your first betta or running a high-tech planted scape, Shoal & Stem helps you stay on top of every tank — without the spreadsheets.
SCAN & SCORE
• Point your camera at a test strip and the AI reads your parameters in seconds — no squinting at tiny color charts.
• Get an instant Tank Health score with a plain-English breakdown of what's thriving and what needs attention.
LOG EVERYTHING
• Track pH, ammonia, nitrite, nitrate, GH, KH, temperature, dissolved oxygen and more, with clean charts over time.
• Keep a photo journal for every tank — document your scape, your fish, and the key moments as they grow in.
• Record livestock, plants, water changes, dosing, and equipment all in one place.
STAY ON SCHEDULE
• Set reminders for water changes, fertilizer dosing, water tests, filter cleanings, and feedings.
• See what's due across all your tanks at a glance — and reschedule from the day you actually did it.
ASK FINN, YOUR AI TANK EXPERT
• Chat with Finn about stocking, water chemistry, algae, or a sick fish — grounded in your tank's real data.
• Just tell Finn what you did, and he'll log it for you.
KNOW WHAT FITS
• Browse hundreds of freshwater fish, shrimp, snails, and plants with real care requirements.
• Check stocking and bioload before you buy, so your tank stays healthy.
SHARE & DISCOVER
• Follow other keepers, share your tanks, and get inspired by the community.
No paywalls. No locked features. Just a better way to keep your aquariums thriving.
Start your first tank today.
