Supply planner — know when you'll run out
Tell us how much you use per day and we'll calculate how long your basket lasts and when to buy more. No guessing, no pressure to "buy now".
The calculator is free and doesn't require an account.
How it works
Enter your dose
For each item in your basket, enter how much you use per day. It's always your own number — from the leaflet or your pharmacist. We never suggest it.
We calculate your supply
From the number of packs in your basket and your dose, we work out how many days it will last and the exact date your supply runs out.
We remind you
Create a free account and we'll e-mail you 7 days before your supply runs out — with a link straight to the price comparison.
We calculate honestly
We calculate prices and supply, not doses — you always enter the dose yourself.
We don't know your specific pack's expiry date — check it on the box.
We plan a quarter's supply, not a year's — so the dose and price you see stay accurate. Over-the-counter (OTC) medicines and supplements usually have a 2–3 year shelf life from manufacture (a general figure, not for your specific pack).
Medicine cabinet Autopilot
Instead of entering a dose for every item by hand, Autopilot will ask you for it in one short conversation — then work out how many days it lasts, when it runs out and how many packs to buy, on its own. You just review and confirm. A Premium feature.
