- Two tools: the WHO growth percentile calculator and the nap schedule planner, in English or Czech.
- One snippet each: a plain iframe and one line of credit. No script needed, so it works on most blogs and site builders that allow an iframe.
- Private for your readers: no cookies, no IDs, no ads. What they type is calculated in their browser and stays there.
- Free. All we ask is that you keep the credit links.
Baby growth percentile calculator
Weight, length and head circumference on the WHO Child Growth Standards from birth to 5, in lb or kg, with corrected age for babies born early and a plain-words verdict. Parents can add measurements over time and see their baby's own curve.

Baby's age and this morning's wake-up time in; today's naps, bedtime and a live "next nap in…" countdown out, by wake windows from newborn to 3 years. When a nap runs short, the rest of the day re-plans itself.

Optional: let the frame grow with the tool
The iframe works as it is: when the tool gets taller than the frame, it scrolls inside. If your site lets you add a script, paste this once anywhere on the page and every Mamoon frame takes exactly the height its tool needs.
<script>
addEventListener("message", function (e) {
if (e.origin !== "https://mamoon.app" || !e.data || !e.data.mamoonEmbed) return;
document.querySelectorAll('iframe[src^="https://mamoon.app/"]').forEach(function (f) {
if (f.contentWindow === e.source) f.style.height = e.data.mamoonEmbed.height + "px";
});
});
</script>The terms, in plain words
- Free for any site, personal or commercial.
- Keep the credit: the line under the iframe with its two links, and the "Free tool by Mamoon" line inside the tool. Don't hide, crop or cover them.
- Don't change the tool or put it in a frame that makes it look like your own.
- The tools give information, not medical advice. Their sources (WHO, CDC, AAP, AASM) are listed on the growth calculator and nap planner pages. We keep the embeds up to date and may improve them.
- We may change or retire an embed. If we ever retire one, its address will lead to the tool's page on mamoon.app. The tools come as they are, without any warranty.
What your readers get, and what we see
The embed puts no cookies and no identifiers in your readers' browsers, shows no ads and loads nothing from third parties: every file comes from mamoon.app. What a reader types is calculated in their browser and kept there, so it's still filled in when they come back. Like the rest of our site, the embed counts views without cookies: we see that the growth calculator was opened on your site (the site's name; we don't learn who the reader is), which is how we learn where our tools help. The details are in our privacy policy.
Does the embed slow my page down?
Hardly. With loading="lazy" the browser loads the tool only when a reader scrolls near it, and the whole tool is a few small files with no tracking or ad scripts.
Can I change the colors or the size?
The size, yes: change height, or use the optional script above. The colors and the credit stay as they are, so the tool looks the same everywhere it appears.
Do links inside the tool take readers off my page?
They open in a new tab, so your page stays where it was.
Is it really free?
Yes. We make Mamoon, a baby monitor app, and the tools are how parents find us. The credit link is the only thing we get in return.
