What’s New Version 1.0.10

This update puts Finn — your aquarium sidekick — front and center, plus a lot you've asked for. Smarter Finn • Personalized tank-health summaries — Finn reads your own logs and tells you what's really going on, not a one-size-fits-all line. • Just tell Finn what you did — "did a 25% water change," "lost a tetra" — and he logs it for you, no forms. • New Updates inbox — announcements and notes from Finn, all in one place. • Rate Finn's answers with a thumbs up or down so they keep getting sharper. Stocking you control • Edit a fish's stocking history — fix a "died" that should've been "rehomed," or undo your most recent entry. • Tap any history entry to jump straight to that species. • Remove a logged water change right from the schedule. Discover and community • A new Discover feed — fresh tanks, journal highlights, and what the community is up to. • Public profiles, plus followers and following. • Can't find a species? Request it and we'll add it — and the catalogue just grew by a lot. Polish • Smoother camera and faster photo uploads. • Dozens of small refinements throughout. A lot of this came straight from your suggestions — keep them coming.

Description

Shoal & Stem is the freshwater aquarium journal hobbyists actually use. Whether you're keeping your first betta or running a high‑tech planted scape, Shoal & Stem helps you stay on top of your tanks — without spreadsheets. SNAP, SCORE, AND LOG YOUR TANKS • Scan test kits with your camera. The AI reads your parameter pads in seconds — pH, ammonia, nitrite, nitrate, GH/KH, phosphate, even copper and iron — so you're not typing numbers by hand. • Score your tank's health. Get an at‑a‑glance number across factors like stocking, water quality, equipment, maintenance, plant cover, and ecosystem maturity. • Track water changes. Log volumes, get reminders, and see how consistent you've been. • Photo journal. Document your scape over time with notes and dated photos — snap a full‑tank shot straight from the camera, and rotate any shot with a tap. • Archive retired tanks. Break down a scape without losing it — archived tanks keep their full journal, photos, and history. ASK FINN ANYTHING Finn is your AI aquascaping companion — versed in aquarium care, plant biology, fish compatibility, water chemistry, and aquascaping technique. Finn looks at your real water readings — now including copper and iron, so it can flag copper that's risky for shrimp and snails — and answers anything from "why is my plant melting?" to "what fish can I add to my 20 gallon?" PLAN YOUR STOCKING The Stocking Calculator tells you if your tank is overstocked. Pick species, check compatibility, get a balanced bioload number, factor in your water‑change routine, and let Finn weigh in on your plan. CONNECT WITH OTHER SCAPERS • Browse community tanks and see each keeper's fish, shrimp, and plants up close • Inspire (heart) tanks you love • Comment, follow, and chat • Forum for deep‑dive aquascaping discussions WHAT'S FREE Everything. The app is free with unlimited tanks. No subscription. No paywall on core features. PRIVACY‑FIRST We don't sell your data, share with advertisers, or run third‑party analytics SDKs.

Build 887212793v1.0.92026-06-20 16:44:01
You talk, Finn logs. Just tell Finn what you did, like "did a 30% water change," "nitrates are 20," or "added 5 amano shrimp," and he records it straight to your tank. He shows you the draft first; you tap to confirm. No forms, no menus. Also in this update: - Photos keep their orientation, so portrait shots no longer upload sideways. - A faster, clearer Finn, with thumbs up/down on his answers so he keeps improving. - Smoother sign-in and a tidier journal camera.
Build 886657195v1.0.82026-06-08 17:08:07
A few new ways to track and share your tanks: • Share your tanks — a new Share button lets you post your aquarium journal to Instagram, X, Facebook, Reddit, and Pinterest, or copy a link to share anywhere. • Amphibians have arrived — track axolotls and other amphibians, now with their own category and icon. • Smarter health scores — add your filter's flow rate (optional) and Finn factors your real filtration into its stocking and health analysis. • Smoother stocking screen — the inhabitant photo carousel now swipes cleanly left and right. • Fixes and polish — resolved an issue with following tanks, plus performance and stability improvements.
Build 886599062v1.0.72026-06-06 16:23:59
This update is all about photos. • Rotate in a tap — straighten any photo right where you see it: your tank gallery, your journal photos, and inside a journal entry. • A bigger, better look — journal entries show your photos large now, with a swipeable carousel when there's more than one. • Faster fish photos — "Photograph inhabitants" jumps straight to the camera, and your shot is set as that fish, shrimp, or plant's photo automatically. It'll even nudge you when a photo is still a community one so you can add your own. • Tidier tanks — inhabitants you no longer keep drop off your tank on their own. Plus a pile of smaller fixes and polish. Thanks for keeping your tanks with us.
Build 886555104v1.0.62026-06-05 16:00:55
• Copper & iron tracking — log two more water parameters by hand, or scan your test kit and let the app read them in. Finn factors them into your tank's health and advice — handy for keeping copper away from shrimp and snails. • A more visual community — open another keeper's tank and their fish, shrimp, snails, and plants now appear as large, photo‑forward cards instead of thumbnails. Each photo is labeled as yours, the owner's, or a community photo. • Rotate your photos — straighten sideways tank and journal shots with a new rotate button. • Reliability & polish — tanks open dependably from Explore, the camera no longer reopens after deleting a photo, Finn's health summary no longer cuts off, and we improved sign‑in autofill and accessibility throughout.
Build 886454726v1.0.52026-06-03 17:18:43
- Fixed an issue where some tank photos could fail to load. Images now load reliably in your tanks and in Explore. - Smarter stocking guidance from Finn, plus performance and stability improvements.
Build 886364780v1.0.42026-06-01 16:31:26
We've been busy below the waterline. This update brings a big journal upgrade, smarter photos, and faster everyday tank care. Journals, reimagined • Entries now open with a full-width hero photo and a swipeable gallery • Read the journals on any tank you visit, not just your own Photos that just work • Sideways shots now save right-side up across journals, tanks, and inhabitants • Full-screen photos stay put; swipe cleanly through the gallery • Swipe through a tank's photos right on its page Faster tank care • Log a water change straight from My Tanks • A red badge on the app icon shows how many tanks are due A better Explore • Sort tanks by Most popular, Newest, Most viewed, or Healthiest • See each tank's health score at a glance Little things, big difference • Water parameters now show full names, like KH (Carbonate Hardness) • A photo carousel of your fish and plants in every tank's stocking • The camera shows which tank you're saving a photo to • Plus bug fixes and polish throughout Happy keeping!
Build 886131804v1.0.32026-05-26 17:52:53
This update helps you keep your tanks organized and looking their best: • Archive tanks — Finished with a tank for now? Archive it to tuck it out of your active rotation. Archived tanks stay on your profile with an Archived badge and stop sending water-change reminders, so your dashboard only flags the tanks you're actively running. • Quick tank photos — A new "Add a tank photo" shortcut in the camera lets you capture a full-tank shot straight to your gallery — great for a cover photo or tracking progress — without starting a journal entry. • Faster inhabitant photos — Tap any inhabitant to jump straight to your camera or photo library, then choose whether to set the new shot as that species' photo. • A cleaner tank screen — The back and edit buttons now sit in their own header bar instead of overlapping your cover photo. • Polish throughout — A tidier My Tanks layout, consistent in-app dialogs, and smoother scrolling on every screen.
Build 885970946v1.0.12026-05-21 22:34:51
What's New in 1.0.1 Stocking dates - When you add a species, set the real date you added it, and edit that date anytime from a species' Stocking history. - Cataloguing a tank you've had for a while? Finn now reads it as the established setup it is, instead of a brand-new, freshly stocked one, so your health score is accurate. Smarter health analysis - Finn factors in when your stock was added, and you can re-analyze any time after fixing a date. A bigger species library - New species added, including several crayfish: White River Crawfish, Yabby, Red Claw, and more. Polish and fixes - Smoother photos: pinch-to-zoom, gallery, and camera improvements. - More reliable sign-in and sessions. - Various stability and performance improvements. Thanks for the feedback that shaped this update. Keep it coming!
