Peace of mind, one fever at a time.

Feverly is the fever tracking app that remembers the important stuff, so you don't have to. Always know when the next paracetamol or ibuprofen is safe — and track every episode, dose, and pattern along the way.

What Feverly does

Three things, done well — for the nights you're not sure what to do next.

No clinical jargon, no overwhelming dashboards. Just the information you need, when you need it.

Track every episode

Log temperatures, symptoms and notes in seconds. Feverly stitches them together into clear illness episodes — start, peak, and clear — so the story tells itself.

Never guess the next dose

Know exactly when the next paracetamol or ibuprofen dose is safe to give. Calm countdowns, gentle reminders, and a clean dose history — no guesswork at 3am, no mental maths.

Spot the patterns

Days between episodes. Year-over-year frequency. All-time peak. The numbers that turn a tired memory into a coherent health history you can actually share.

A closer look

Designed for the moments you'd rather not be in.

Feverly is built to be useful one-handed, in the dark, on three hours of sleep.

Why we built this

Feverly started as a Google Sheet — built at 2am for a toddler with PFAPA (periodic fever syndrome), causing recurring fevers every 7 to 10 days.

It worked. It also made us realize how many parents are out there doing the same thing — scribbling temperatures on the back of receipts, second-guessing the last dose, trying to remember what the doctor said three weeks ago. Whether your child has PFAPA, another recurring fever condition, or just catches every bug going around, Feverly is the fever diary and medication tracker a sleep-deprived parent actually deserves.

We'll only email when there's something real to say.

Honest answers

Things you might be wondering.

Is Feverly a medical device or diagnostic tool?
No. Feverly is a tracking and organization tool — it remembers what you log and helps you see patterns. It does not diagnose, prescribe, or replace your pediatrician. When something genuinely needs medical attention, please call your doctor.
How safe is my child's data?
Your data is encrypted at rest and in transit, GDPR compliant, and stored on European servers. We never sell it, never share it, and never use it to train AI models. You can export or delete everything any time, with one tap.
Will it work for my child?
Feverly is built to work for any parent, any child. The founder's toddler has PFAPA (periodic fever syndrome) — a recurring fever condition causing high fevers every 7–10 days — so the metrics that matter most for recurring fever conditions are front and center: average days between episodes, peak temperatures, year-over-year frequency. Works just as well for the regular winter cold.
How much will it cost?
Free during early access — no credit card, no commitment. 
When will it be available?
We're targeting the second half of 2026, right in time for back-to-school season. Waitlist members get early access - we'd rather ship something you actually love than rush something you tolerate.
Can both parents use it?
Multi-caregiver access is on our v2 roadmap — so two parents (or a parent and a grandparent) can log doses and see the same history in real time. For the time being, you can just log in with the same account.
