If you keep a bearded dragon and you've gone looking for an app, two very different kinds of tool show up. One is a calculator like ReptiCalc — you punch in numbers and it helps with husbandry math. The other is a tracker like Beardie Days, the bearded-dragon journal we make. They're easy to confuse and genuinely easy to use together, so here's a fair breakdown of what each is for.
The core difference: a calculation vs a history
- ReptiCalc answers point-in-time questions. How much should I feed at this age? What does my supplement schedule look like? It does husbandry math across reptile species, and it does it well — but it isn't designed to remember your dragon week to week.
- Beardie Days answers questions about change over time. How fast is my dragon growing? When was the last shed? What did I feed last week? It keeps a running record of one specific animal so a pattern can emerge.
Put simply: a calculator gives you a number now; a tracker gives you a story over months. We made the same argument against the most common DIY approach in Beardie Days vs spreadsheet tracking.

Where ReptiCalc still wins
Credit where it's due. When you have a husbandry question right now — a feeding amount, a supplement question, a sanity check across species — a dedicated calculator is fast and focused, and it covers reptiles far beyond bearded dragons. If that's what you need in the moment, ReptiCalc is a solid pick, and it pairs perfectly well with a tracker.
Where Beardie Days fits better
Choose a tracker like Beardie Days if:
- You want to watch your dragon grow from hatchling to adult on a real growth chart.
- You want sheds, feeding, and weights on a timeline you can scroll back through.
- You're documenting morph genetics or a breeding line with family trees.
- You want a beautiful photo record — and the care context — for the specific animal you love.
"ReptiCalc told me how much to feed. Beardie Days is where I actually see that my dragon doubled in size since spring."
The bottom line
This isn't really an either/or. ReptiCalc is the calculator you reach for when you have a husbandry question; Beardie Days is the journal that remembers your dragon's whole life. If you only want the math, a calculator is enough. If you want the history — growth, sheds, genetics, photos — that's what Beardie Days is built for.
Frequently asked questions
What is the difference between Beardie Days and ReptiCalc?
ReptiCalc is a husbandry calculator: you enter details and it helps with reptile care math like feeding amounts and supplement guidance across many species. Beardie Days is a longitudinal journal for your specific bearded dragon — it records weight and length over time, sheds, feeding, morph genetics, and photos so you can see your dragon's whole history.
Is there an app to track a bearded dragon's growth over time?
Yes. Beardie Days is built specifically for tracking a bearded dragon from hatchling to adult — logging weight and length as a growth chart, documenting sheds and feeding, recording morph genetics and family trees, and keeping a photo timeline of your dragon's journey.
Is Beardie Days free?
Beardie Days is free to download, with an optional upgrade for keepers who want unlimited dragons and advanced features. It is a privacy-first iOS app, so your records stay on your device.
