- Download
ReptiLogic-Setup-1.1.1.exe - Run the installer — choose your install location and create shortcuts
- Launch ReptiLogic — the first-run wizard will guide you through setup
No additional software required.
- Track animals with photos, morphs, weight, DOB, acquisition info, and notes
- Auto-generated Animal IDs (e.g.
BPF042-AhA) or enter your own to match an existing system - Grid and list view with filtering by species, sex, status, and search
- Full animal history — breeding records, weight log, feeding log, photo gallery
- Link parents at time of adding — lineage builds automatically over time
- Clickable family tree on the Lineage tab, going back as many generations as recorded
- Bulk import from CSV (Settings → Import)
- Per-animal health dashboard with weight trend chart
- Log health issues with category and severity, track medications, record vet visits
- Dashboard reminders for animals overdue on feeding or weighing
- Full pairing lifecycle: Planned → Active → Gravid → Laid → Hatched
- Terminology adapts for live-birth species (Born instead of Hatched, etc.)
- Log clutches with egg count, incubation details, and individual offspring records
- Add Babies Wizard — step through each hatchling, assign name/sex/weight/morphs/ID, add them all to your collection at once with parents auto-linked
- Suggested Pairings — scans your active collection and recommends pairings based on genetics
- Full Punnett square engine: recessive, co-dominant, dominant, line-bred, and sex-linked
- Allele complex support — BEL complex (Lesser, Butter, Mojave, Phantom, Mystic, Russo, Special, Mocha), Yellow Belly complex, 8-Ball complex, Bearded Dragon Scale complex, and more. Two alleles from the same complex automatically produce the correct result (e.g. Lesser × Mojave = BEL)
- Sex-linked Banana/Coral Glow — Male Maker and Female Maker inheritance modelled correctly (~93% sex ratio skew). Maker type stored per animal and used automatically in From Collection mode
- Outcome cards showing morph name, probability, expected clutch count range, and sex ratio notes
- Clutch size projection based on species typical range
- Health warnings for all morphs with known concerns
- Use animals from your collection or enter genes manually
- Ball Python — 130+ morphs with full allele groups, health concerns, sex-linked Banana/Coral Glow
- Western Hognose — 25+ morphs with corrected inheritance types (Anaconda = incomplete dominant, Toffee Belly = incomplete dominant, Lavender = recessive, Pastel RBE = dominant)
- Leopard Gecko — 18 morphs including all three non-allelic albino strains (Tremper, Bell, Rainwater), Mack Snow, Giant, Enigma and Lemon Frost with ethical health warnings
- Bearded Dragon — 14 morphs including Leatherback/Silkback (health flagged), Dunner, Zero, Witblits, American Smoothie
- Add custom morphs for any species — included in the calculator automatically
- Professional print-ready document from any animal's detail page
- Animal photo, morphs, 2-generation lineage pedigree, weight log, feeding history
- Breeder header with name, logo, website, and social links (Instagram, X, YouTube, TikTok, Facebook)
- Automatic compressed ZIP backups on app open or close, configurable retention and folder
- One-click restore from any saved backup
- Export collection, breeding records, and morphs to CSV
- CSV import with auto format detection
- Breeder profile with logo and social links (used in print reports)
- Auto-generate or manual Animal IDs
- Light and dark mode
- Configurable feeding and weighing reminder thresholds
- Move database to any folder (OneDrive, Dropbox, etc.)
5-step setup covering database location and automatic backup configuration. All settings adjustable later.
- Node.js 22 or 24 LTS — https://nodejs.org
- Visual Studio 2022 with the "Desktop development with C++" workload
