Mancae is a tracker for hobbyist isopod keepers. Whether you have one Armadillidium colony, a shelf full of Cubaris morphs, or a freshwater Asellus tank, Mancae helps you log husbandry, watch populations grow, and keep your records in one place.

Calm, focused, and offline.

WHAT YOU CAN DO
- Track unlimited colonies — name, species, morph, founder count, source.
- Quick log daily checks: fed, misted (or topped-off and water-changed for aquatic colonies), cleaned, calcium, temperature, humidity.
- Batch log across multiple colonies at once — feed the whole shelf in one tap, or mark a husbandry day across every active colony.
- Backdate any log entry — record what happened yesterday or last week without faking the timestamp.
- Estimate population without counting every isopod, using a guided photo-based method that accounts for visibility coefficients and species size.
- Mark mancae sightings — with first-wave detection — to track breeding pace.
- Set custom reminders for misting, feeding, substrate changes, water changes, and anything else.
- Track lineage when you split a colony, so you know which lines came from where.
- Browse a built-in library of 50+ species with husbandry references — temperature, humidity, ventilation, substrate, diet, breeding, behavior, and background. The Library includes both terrestrial and freshwater aquatic species, filterable by habitat and difficulty.
- Add custom species not in the library, with full husbandry fields — mark your species as terrestrial or aquatic and Mancae adapts the husbandry labels automatically.
- Visualize each colony with charts: population trend over time, environmental correlation, and mancae sighting timelines.
- See cross-colony Insights: total population, species breakdown, growth trends.
- Take and attach photos to colonies and log entries. Pick a hero photo for each.
- Switch between light and dark mode, with four color palettes (moss, amber, blue, rose).
- Choose your preferred units (Celsius / Fahrenheit, cm / inches).
- Export all your data as JSON or CSV anytime, or import from a previous backup.

PRIVACY
Mancae is offline. All your data stays on your device. No accounts, no servers, no analytics, no advertising. If you uninstall, the data is removed with the app (unless exported first).

WHO IT'S FOR
Hobbyists keeping any number of isopod colonies — from a first Porcellio scaber to a serious collection of rare Cubaris morphs, or aquarists keeping freshwater Asellus. The Library covers Armadillidium, Armadillo, Porcellio, Porcellionides, Cylisticus, Cubaris, Merulanella, Oniscus, Philoscia, Trichorhina, Venezillo, Helleria, Hemilepistus, Asellus, Caecidotea, and more.

Mancae is not a substitute for advice from your breeder. Care references are starter information; for rare or sensitive species, always defer to your source's guidance.
