I have bred geckos for years, and I built ReptiDex because the tools I tried were built for lizards in general and never quite fit how gecko people actually work. There is no single "best" app for everyone, so instead of ranking products, here is what strong gecko breeding software has to do, and how ReptiDex handles each point. Judge any tool, including this one, against the same list.
It has to model gecko lineage, not only a pairing log
A list of who was paired with whom is not a pedigree. Geckos change hands often, and a hatchling you sell may show up two clutches deep in someone else's project. Good software builds a real multi-generation pedigree and can represent a parent that lives in another breeder's collection, not only animals in your own account. ReptiDex resolves sire and dam within your collection and links to cross-collection parents so the tree stays accurate after a sale.
It has to handle polygenic and line-bred traits
Single-gene morph calculators are common. Geckos are where they fall short. Traits like the ones line-bred in crested and leopard geckos are polygenic: they express on a spectrum and depend on how you pair over generations, not a tidy dominant or recessive result. Software that only speaks in simple Mendelian outcomes will mislead you. ReptiDex records the traits you actually select for and keeps the pairing history behind them, so a line you spent years developing is documented rather than guessed at.
Records have to transfer with the animal
When you sell a gecko, its weight history, shed and feeding logs, and lineage are worth as much to the buyer as the animal. If that history lives only in your private account, it dies at the sale. The best tools let the record move with the animal. ReptiDex supports transferring an animal so the new keeper inherits its history instead of starting a blank card.
A buyer has to be able to verify what you claim
A QR code on an enclosure or a sale listing that opens the animal's live public record does more for trust than any description. It lets a buyer confirm age, lineage, and morph before they commit. ReptiDex generates a public record you control, so the QR always points at current, real data rather than a screenshot.
It should connect to the wider gecko community
Clubs, registries, and shows are how gecko lines gain reputation. Software that keeps your data walled off makes that harder. Being able to share a pedigree link or a public record into a club or a listing, without exporting screenshots, keeps your program legible to the people who matter.
Key takeaway
The honest checklist
- Real multi-generation pedigree, including cross-collection parents.
- Trait tracking that respects polygenic and line-bred gecko genetics.
- Records that transfer with the animal on a sale.
- A QR or link that opens the live public record for buyers to verify.
- A full export, so you are never locked in.
- Both phone and web, because you log at the rack and review at a desk.
No tool is perfect, and you should hold ReptiDex to this list as strictly as any other. If it does not do one of these well for your program, that is worth knowing before you commit your records to it.
