TankWise

TankWise helps freshwater aquarium keepers track the tank details that matter day to day: water quality, livestock, fish health, plants, photos, notes, and receipts.

Build a profile for each aquarium with size, temperature, lighting, CO2, fertilizer, photos, and aquarium biotope. Log water tests over time, review parameter graphs, and keep a timeline of notes, photos, water tests, and receipts.

Add fish and plants from built-in freshwater catalogs, or use optional web lookup to help fill care fields for species that are not already listed. The livestock and evaluation screens compare fish needs against tank size, water parameters, and current stocking so you can spot obvious risks before adding new fish.

TankWise is designed for freshwater aquariums. It does not require an account, login, cloud sync, or a backend. Most records stay in local app storage on your device. Optional species web lookup uses the internet only when you ask the app to search for fish or plant information.

Key features:

- One fully featured freshwater tank included free
- Water quality logging and parameter graphs
- Tank overview built around current water parameters and livestock fit
- Fish and plant catalogs with thumbnails
- Optional fish and plant web lookup for unlisted species
- New fish evaluation for one or more candidate fish
- Purchasing guide for new fish
- Aquarium biotope targets, including custom targets
- Notes, progress photos, water tests, and receipts in a chronological timeline
- Local receipt photo storage
- Light and dark mode

All current tools are included for the first tank. An optional one-time Unlimited Tanks purchase lets you create and manage additional freshwater aquariums. There is no recurring subscription.

TankWise provides record keeping and educational guidance. Aquarium decisions should still be checked against your own observations, trusted care sources, and professional advice when needed.
