Searching for the best leopard gecko apps usually means one of three quite different problems. You want to know whether your gecko is actually growing normally. You want something to stop you over- or under-feeding. Or you've noticed something — a stuck shed, a skipped week of food, a tail that looks thinner — and you want a sanity check before you decide whether it's a vet visit.
No app does all three well, and the ones that claim to are usually mediocre at each. What follows is organised by the job rather than as a countdown, so you can install the one you actually need. Worth saying up front: a leopard gecko commonly lives 15 to 20 years. Whatever you pick, you're choosing where two decades of records will live, which is a good reason not to pick the one with the nicest icon.
Best for tracking growth over time: Beardie Days
Beardie Days is ours, and it exists because generic pet apps are built around cats and dogs — they want feeding schedules and vet appointments, and they have no concept of growth stages, morphs, or the difference between a healthy animal and an underweight one. It covers bearded dragons and leopard geckos, and the model is the same for both: records, not reminders.
Each animal gets a full profile — morph, sex, acquisition date, health status and growth stage — and then a growth timeline. You record weight in grams and length, attach a photo, and add a care note: shed quality, a feeding change, a behaviour you noticed, a vet visit. Over months those entries become a chronological visual story you can scroll through in full-screen, and that's the point. A single 62g reading tells you nothing. The same gecko across eighteen dated photos and eighteen weights tells you everything, and it's the view that makes a slow decline visible while it's still slow.
For anyone breeding, there's lineage tracking: link parent animals to their offspring and build a family tree across generations — which pair produced which clutch, when hatchlings were separated, how each generation's morphs came out. Batch photo import handles the backlog already on your camera roll. Everything exports to CSV and backs up, and none of it leaves your device — there's no account and no cloud requirement.
What it deliberately doesn't do: it won't identify your gecko, diagnose it, or tell you when to feed. It's a record, and it assumes you're the one making the decisions. Free for your first animal; Premium is $3.99/month, $19.99/year or $49.99 lifetime. (Related: our bearded dragon growth chart explains the same weighing method in more depth.)
Best for feeding intervals: Reptile Rocket
Reptile Rocket is built around the observation that obesity is one of the most common reptile health problems, and it does something unusual about it: rather than just reminding you to feed, it enforces the interval, and won't offer food more often than necessary. For a leopard gecko — an animal it is genuinely easy to overfeed, especially on waxworms — that constraint is the feature.
It also tracks sheddings and the growth process, with measurements and photos so you can see change over time, and it has tools aimed at keepers running large collections. Free, and rated around 4.3 stars across roughly 100 ratings. Pick it if your honest failure mode is feeding on vibes.
Best for a second opinion: Exotic Reptile Care
Exotic Reptile Care is the broadest app here — snakes, geckos, turtles and lizards — and it combines AI-powered species identification from a photo with monitoring for feeding, growth, shedding and habitat conditions. At 4.8 stars across 112 ratings it's the best-rated app on this page.
It's the right pick if you keep more than one kind of reptile and want a single app across all of them, or if the habitat side — temperatures and conditions — is where you feel least confident. Treat the AI as a prompt to look more carefully, not as a diagnosis; that's true of every app in this category.
Best for quick care questions: Gecko Expert
Gecko Expert is the only app here built specifically and exclusively for geckos. It's an AI gecko assistant: upload photos for an instant health assessment, get guidance on spotting early warning signs, and get help optimising your setup. Free, though at 4.25 stars across only 16 ratings it's a much younger and less proven app than the others.
It suits a first-time keeper in the phase where every shed and every skipped meal raises a question, and a searchable answer at 11pm is worth a lot. It is not a substitute for an exotics vet, and it isn't where you'd keep long-term records.
Best free option: a kitchen scale and a note
Worth naming honestly, because for one gecko it genuinely works. A digital kitchen scale that reads to the gram costs almost nothing, and a monthly note with the weight and a photo will catch most of what matters. No subscription, no app to learn.
What you give up is legibility. A year of loose notes and an undated camera roll is technically the same data and practically unreadable — the whole value of a growth record is being able to see the shape of it at a glance, and that's exactly what a pile of notes won't give you. Start here with one animal. Move when you can no longer answer "was last spring's shed worse than this one?" from memory.

"He'd dropped eleven grams over four months and I hadn't noticed, because I saw him every day. The photos side by side were what made it obvious."
The bottom line
If you keep one leopard gecko and you're new to it, install something with answers in it — Gecko Expert or Exotic Reptile Care — and weigh the animal monthly on a kitchen scale. That covers you.
If you've been keeping for a while, or you have several animals, or you're breeding, the useful app is the one that still has your data in it in five years. That means real records: dated weights, photos, notes, and an export you own. Reptile Rocket is the pick if feeding discipline is your weak point; Beardie Days is the pick if what you want is to look back across a year and actually see what happened.
Frequently asked questions
What is the best leopard gecko app?
There isn't one best app, because keepers need different things. If you want a long-term record of how your gecko is growing — weights, photos, notes on sheds and appetite — Beardie Days is built for exactly that. If you want the app to tell you when to feed and to stop you overfeeding, Reptile Rocket is designed around feeding intervals. If you want a second opinion on whether something looks wrong, Exotic Reptile Care and Gecko Expert both use AI to assess photos. Most keepers end up with a record-keeper plus one reference app.
Is there a free leopard gecko app?
Yes. Reptile Rocket, Exotic Reptile Care and Gecko Expert are all free to download. Beardie Days is free for your first animal, with Premium unlocking unlimited animals, batch photo import and watermark-free sharing at $3.99 monthly, $19.99 yearly or $49.99 lifetime. And the genuinely free option is not an app at all: a digital kitchen scale and a note on your phone will record weights perfectly well for a single gecko.
What is the best app for tracking leopard gecko weight?
Weight is the single most useful number you can record for a leopard gecko, because gradual weight loss is often the first visible sign of trouble — well before behaviour changes. Beardie Days records weight in grams and length alongside a dated photo, so each entry sits in a chronological timeline you can scroll rather than a list of numbers. Reptile Rocket also tracks measurements and shedding over time. Whichever you choose, weigh on the same scale at the same point in the feeding cycle so the numbers stay comparable.
Do I need an app to keep a leopard gecko?
No. A leopard gecko needs correct temperatures, a humid hide, appropriate feeders and supplementation — none of which an app provides. What an app gives you is memory. Leopard geckos commonly live 15 to 20 years, and questions like whether this shed took longer than usual or whether the appetite drop is seasonal are impossible to answer from recollection. If you keep one animal and weigh it monthly, a notebook is enough. Past three or four animals, structured records stop being optional.
