Problems ReptiDex Solves
Built to fix the real frustrations of running a breeding program.
Buyers expect lineage, photos, and real records.
Screenshots and spreadsheets don’t build trust at shows or online.
ReptiDex: scan a QR code and show the full live record, pedigree, and history instantly.
Your breeding data lives in 5 different places.
Notes, spreadsheets, photos, and memory. Nothing actually connects.
ReptiDex: animals, genetics, pairings, clutches, and records all tied together.
Switching tools means starting over.
Hundreds of animals. Hours of manual entry. Most people never make the move.
ReptiDex: import your spreadsheet and get set up without rebuilding everything.
ReptiDex replaces your spreadsheets, scattered notes, and per-animal-fee apps with one tool built by a breeder.
One system for records, breeding, lineage, and genetics
ReptiDex replaces the spreadsheets, notes, calculators, and disconnected apps breeders piece together just to manage one collection.
Live records, QR codes, and pedigrees that build buyer trust
Give buyers more than a screenshot. ReptiDex lets you generate printable pedigrees, share live animal records with QR codes, and keep lineage, history, and genetics attached to every animal from hatch to sale.
- Printable pedigrees showing up to 5 generations of lineage
- QR codes for every animal: print, stick on the tub, scan at shows
- Animal transfers: sell with the full record history attached
- Lineage, genetics, and history attached to every animal
- Public animal profiles buyers can scan without an account
Run pairings, clutches, eggs, and hatch outcomes in one place
Stop managing breeding season in spreadsheets and notes. ReptiDex gives you one place to track pairings, clutch events, egg progress, hatch outcomes, and the records that connect back to each animal.
- Breeding seasons with connected pairings and clutch history
- Pair management with pairing dates and separation tracking
- Track each egg from laid to candled, pipped, hatched, or failed
- Candling notes and photo documentation in the same workflow
- Expected hatch dates and hatch outcomes tied back to the project
Keep your whole collection organized, searchable, and easy to manage
ReptiDex gives you one place to organize every animal, store the details that matter, and find what you need fast. No more hunting through photos, spreadsheets, and scattered notes just to answer a simple question.
- Track your full collection across 137 supported species
- Store photos, captions, and key details with each animal
- Organize animals into custom groups that match how you actually operate

Built for Crested Gecko Breeders, Ball Python Breeders, and Beyond
ReptiDex was built by an active crested gecko breeder. The pedigree app, breeding records, and growth tracker features were designed around how crested gecko programs actually run: seasonal pairings, clutch-by-clutch records, morph documentation, and buyers who expect lineage paperwork. Those same tools work for ball python breeders, leopard gecko breeders, corn snake breeders, and anyone keeping serious reptile breeding records. ReptiDex supports 137+ species, and if yours is not in the app yet, you can request it right inside ReptiDex.

Four things that matter to breeders.
Built by a breeder
Not a software company that discovered reptiles. Dusty Mumphrey is an active crested gecko breeder who runs Geckistry. He built ReptiDex because nothing else met the standard he needed for his own program.
Records follow the animal
Transfer an animal to a buyer and the full history goes with it: pedigree, health records, weight trends. The buyer gets confidence. You get credibility.
QR codes on every cage
Print a code, stick it on the tub. Scan it at a show. Hand it to a buyer. Instant access to the live record, no app required on their end.
No per-animal fees. Ever.
Simple flat-rate pricing. Free for up to 10 animals. Unlimited animals on Pro for $4.99/month. Your collection grows without the bill growing with it.

Dusty Mumphrey
Active crested gecko breeder. Runs Geckistry.
I built ReptiDex because nothing else met the standard I needed for my own breeding program. After 9+ years as a senior software engineer across fintech, healthcare, and government, I had the tools to build it right. So I did.
I use ReptiDex daily to manage my own crested gecko collection at Geckistry. When something is clunky in a real breeding scenario, I feel it immediately and it gets fixed. That's why the app keeps improving. Not from a roadmap. From actually using it.
