WHY AQUARIUM NOTEBOOK

Most aquarium apps are water parameter loggers. This one is built for breeders. Every screen is organized the way fishkeepers actually think — by tank, by generation, by event — so logging a new birth or a water change takes seconds.

All your data stays on your device. No account, no cloud sync, no data collection.

Made for guppy, betta, and shrimp breeders, and anyone serious about keeping accurate aquarium records.

FREE AND PRO

The free version includes all livestock and breeding tracking, all notifications, backup and export, and PDF reports. Pro is a one-time purchase that removes ads and lifts the limits on aquariums, photos, generations, and custom varieties.
