Needs an update badly!!

I really like this app a lot , but they need to remove the black pearl from the recessive and the hypo from the dominant, and add the Lemon Frost to the Dominant. Polygenic traits aren't needed! Maybe update some pictures as well but not really needed to make it useful. Also they have absolutely no customer service.

Great potential!

I see many reviews that aren't satisfied with the morph selection and wanting sunglow and tangerine included but those are polygenic traits and are almost impossible to calculate. If you breed orange to nonorange then the result will most likely be in between the more you breed orange to orange the more curb Tara the the colors. It is the same principle as bolds and stripes. What I would like to see is ball pythons, crested geckos, and maybe blue tongues. If you would like some helpful apps for leopard geckos try leopard gecko 101 or Ron Tremper's morph guide both of them really helped me get started and I still use them. I hope this was helpful! :)

Please add more morphs

I agree with the post above! I really want to like this helpful app but a lot of morphs & photos are unavailable to be able to calculate properly, especially for new breeders like myself. Please add more morphs like sunglows, tangerines, emerines etc.
