BlubHub – Aquarium tracker

Ohhi

About this app

BlubHub is the logbook for your aquarium. Track your water values, see at a glance whether everything is in balance, and get nudged before something becomes a problem. For saltwater and freshwater tanks alike.

WATER VALUES & TRENDS

• 19 parameters: pH, alkalinity, calcium, magnesium, nitrate, phosphate, salinity, temperature and more
• Test sessions with a timer per test — run several measurements at once
• Charts and history per value, with target bands per tank
• Custom safe bands per tank: a reef makes different demands than an Amazon biotope
• Instantly see what is drifting and in which direction

CARE ON A RHYTHM

• Reminders for water changes, testing, dosing, feeding and filter maintenance
• See what is due today, what is coming up and what is overdue
• Notes per tank, so your logbook is actually complete

YOUR AQUARIUM, COMPLETE

• Inhabitants with species, count and photos — backed by an extensive species catalog
• Tankmate matrix and suggestion wizard: see which species get along
• Equipment overview: filter, lighting, heater, wavemakers
• Multiple tanks side by side, salt and fresh mixed freely

PRIVACY FIRST

• Everything lives locally on your device — no account required
• No ads, no tracking, no third-party analytics
• Optional: back up your logbook online and share a tank with housemates — you choose what gets synced

BlubHub is available in English, Dutch, German, French, Italian and Spanish.
