As answered by people managing Hypernotes and TankBud.
TankBud's answer:
Next.js and React with TypeScript, Postgres on Supabase, deployed on Railway. TankBud is an installable web app (PWA), so it runs in any modern browser and installs to a phone home screen without an app store.
TankBud's answer:
Freshwater and saltwater hobbyists, from one betta tank to a whole fishroom. People who want water tests, maintenance and stocking plans in one place instead of a spreadsheet. There's also a business tier for aquarium service companies, fish stores, breeders, and any other business that manages multiple tanks.
TankBud's answer:
Most aquarium apps do logging or calculators, not both. TankBud ties them together, so the same care data behind the public catalog powers the stocking check in your plans and tanks. There's no cost for hobbyists. Paid plans exist for businesses that manage multiple tanks (fish stores, breeders, service companies with client tanks), and those come with a free trial.
TankBud's answer:
TankBud connects tracking to care data. The catalog covers a growing list of 1,500+ fish, invertebrates and corals plus 300+ plants, with tank size, water parameters, temperament and tank mates for each. The stocking calculator checks a planned community against that data before you buy anything. Saved plans convert into live tanks with the same logs, reminders and photos.
TankBud's answer:
I'm a long time aquarium hobbyist and a software engineer. I first built TankBud for my own tanks because my water tests, maintenance notes and stocking research were spread across a spreadsheet, a notes app and a pile of browser tabs. I worked on it for a couple of years and it's now officially released. The care catalog and stocking calculator are free for anyone to use, no account needed.
