Check your child's medicine and supplement doses — before you give them.
Semak dos ubat dan suplemen anak anda, sebelum anda beri.
One is twice the strength of the other. In a dark bedroom at 2am, that is a very easy thing to get wrong.
That is why Cek Dulu never shows the two side by side. The strength gets its own screen, and asks you to pick up the bottle and read it.
Each answer narrows the next, so there is nothing to confuse and nothing to guess.
Your child's weight and age. Weight gives a safer dose than age, so we ask for it first.
Paracetamol, ibuprofen or an allergy syrup — by name, with the brands you'd recognise on the shelf.
The strength, on its own screen. If you're not sure, we send you to a pharmacist instead of guessing.
We repeat all three back to you first. Only then do you see a number — with a syringe showing you the level.
It checks what you're already giving, and tells you when to stop and see someone.
Enter more than the safe amount and the screen goes red and full-size. Under the minimum age, no dose appears at all — and it cannot be overridden.
Print a dose card with the date, your child's name, the amount and tick boxes for each dose in 24 hours. Stick it on the bottle.
Once you've opened it, it works offline. Add it to your home screen and it opens like an app — no store, no download.
Every result carries the same line: if your doctor or pharmacist told you a different amount, follow theirs. This app checks against published limits — it does not decide treatment.
We built this because we kept answering the same question across the counter, and watching parents forget the answer before they reached the car park.
Yes. There is nothing to buy, no account, and no advertising. Pharmacies can pay to have their own branded version, which is how the project supports itself — but the version you're using stays free.
No. It runs in your browser. If you'd like it to behave like an app, use “Add to Home Screen” — it will then open full screen and work without a signal.
No. The profiles you save stay in your own browser on your own phone. Nothing is sent to a server, because there isn't one.
No, and it will tell you so itself. It checks a dose against published limits. It cannot know your child's history, allergies, or what else they're taking. If your pharmacist gave you a different amount, follow theirs.
We deliberately kept it small. Sedating medicines and anything needing a conversation with a pharmacist were left out on purpose, rather than by oversight.
