What Vivarium Keeper does
Vivarium Keeper is the husbandry logbook for reptile and exotic-pet keepers who are tired of buggy, subscription apps that lose your data. Keep a profile for every animal — ball pythons, leopard geckos, crested geckos, corn snakes, bearded dragons, tortoises and more — and log everything in seconds.
Track feedings with prey type, size and feed response (ate / refused / regurgitated), so you can spot a feeding-strike streak early. Record shed cycles with pre-shed and complete dates, log weights and watch growth charts build over time, and note enclosure temperature and humidity readings on the warm side, cool side and basking spot. Jot defecation, vet visits, treatments and health notes per animal. Breeders get clutch and pairing records.
Every beginner question — how often should I feed, what temps and humidity does this species need — is answered by built-in care sheets for the most common pet species, bundled right in the app. No login. No cloud. No monthly fee. Your data lives on your iPhone and works on a plane.
Free forever for up to 2 animals. Unlock unlimited animals, breeding records, CSV export and full care-sheet library with a single one-time purchase. Start logging today — your reptiles deserve better than a spreadsheet.

What's inside
- Per-animal profiles — User creates a profile per animal with name, species, sex, acquired date, morph and photo; profiles drive every log.
- Feeding log + feed response — User logs a feeding in a few taps: prey type, prey size, and response (ate, refused, regurgitated); a refusal streak banner warns when an animal skips multiple offered meals.
- Shed cycle tracking — User logs pre-shed (going opaque/blue) and shed-complete dates so the time-between-sheds and current shed status are always visible.
- Weight + growth chart — User records weights over time and sees an on-device Swift Charts growth curve to catch weight loss or healthy gain.
- Enclosure temp & humidity log — User manually logs warm-side, cool-side, basking and ambient temps plus humidity readings; latest readings shown against the species care-sheet target ranges.
- Health & defecation notes — User logs defecation, vet visits, treatments, regurgitation and free-text health observations on a per-animal timeline.
Why we built it
Keepers track feeding, sheds, weight and enclosure temps across multiple animals using spreadsheets or notebooks, because existing husbandry apps are buggy, lose data, hide core features behind monthly subscriptions, and require an online account.
What makes it different
Fully offline, no-account, one-time-unlock husbandry log that puts per-animal feeding+feed-response, sheds, weight charts, enclosure temp/humidity and breeding in one place AND bundles species care sheets on-device — unlike Husbandry.Pro (crashes, account-based), HerpTracker and ReptiCare, which gate multi-animal trac…
Who it's for
Hobbyists who want a tool that respects their time, their gear, and their offline life.
