Runway

Reorder reminders for repeat prescriptions

Never run out
again.

Runway works out the day your medication runs out and tells you to reorder well before it does. No dose logging. No streaks. Just arithmetic you can check at a glance.

There is deliberately no dose logging.

A prediction built on a number someone stopped entering three weeks ago is worse than one built on arithmetic they can check. So Runway asks for nothing daily. Nothing to tick, nothing to break a streak on, nothing to feel guilty about at 11pm.

How it works

Four numbers in. Every date out.

  1. 01

    Say what you take

    How many a day, how many come in a box, and the date the last lot arrived. Four numbers, once.

  2. 02

    It does the arithmetic

    Days of supply, the day you run out, and the day to reorder — all on screen, all checkable.

  3. 03

    Your phone tells you

    A notification days before you run dry, at an hour you pick, in the timezone you actually live in.

daysOfSupply  = floor(anchorUnits / unitsPerDay)
runsOutOn     = anchorDate + daysOfSupply
reorderOn     = runsOutOn  - leadDays

The whole app is three lines.

No model, no machine learning, no black box. The anchor is the most recent quantity known to be true — your last order, or a hand count if you have done one — and everything else is calendar arithmetic from there. A wrong answer is obviously wrong, which is the only kind of wrong you can catch.

End-to-end encrypted

We cannot read your medication list.

What you take is the sensitive part, so it never leaves your device readable. Names, strengths and notes are encrypted in your browser under a key only you can unlock, with your passkey. The server keeps ciphertext and the counting numbers it needs to work out dates — and those numbers say nothing about what they are counting.

Lose the device and a recovery code brings the key back. Lose both and nobody, including us, can get the names out again. That is the trade, stated plainly rather than buried.

Built by someone who ran out.

Every detail here exists because the obvious version of it got a date wrong by a day, and a day is the difference between having tablets on the last morning and not.

A count beats a guess

Tip the box out and type what is really in it. That one number corrects every missed dose, doubled dose and mid-box change the maths could never see.

Orders add up

Collect a repeat a week early and you keep the leftovers and a full pack. Runway carries the remainder over instead of pretending the box is all you have.

No password to forget

Sign in with a passkey — Face ID, a fingerprint, a hardware key — or a one-time code to your email. There is nothing to leak.

Dates, never instants

At 23:00 in London it is already tomorrow in Auckland. Every profile carries a timezone so a reorder warning is never a day out.

Lives on your home screen

Install it as an app. It opens to the one thing it exists to answer: is there anything I need to order.

Pause what you are not taking

Seasonal, as-needed, or finished. Paused medications stop predicting and stop notifying without losing their history.

Questions

What Runway does, and what it refuses to.

Is Runway a medicine reminder app?
Not in the usual sense. Runway is a medication tracker: it reminds you to reorder a repeat prescription before you run out of it. It will never tell you to take a dose, and it does not want you logging one.
How does it know when my medicine runs out?
Arithmetic you can check. Tell it how many you take a day, how many came in the last pack and when that pack arrived, and it counts down from there. Every date on the screen follows from four numbers you entered.
Does it work with NHS repeat prescriptions?
Yes — that is what it was built for. It tells you when to reorder, far enough ahead that a repeat has time to be dispensed. If your surgery or pharmacy works with Runway, it can also open their own repeat prescription form with your details filled in. You check it and press Submit yourself: Runway never orders anything on its own.
Can Runway see what medication I take?
No. Medication names, strengths and notes are encrypted in your browser before they are sent, under a key derived from your passkey. The server stores what it cannot read, and a reminder never names a medicine.
What if the pharmacy gives me a different amount?
Say so when you record the order and every date corrects itself. You can also count what is actually left whenever you like — a count beats a prediction, and Runway measures from the count instead.
What does it cost?
Nothing. There is no paid tier, no advertising, and nothing about your medication is sold or shared — which for health data is the only business model that is not a conflict of interest.

Are you a healthcare provider?

Your patients may already be using Runway to track their repeats. Add your practice and, when a repeat is due, Runway opens your own repeat prescription form with their details filled in. They check it and press Submit on your site.

Nothing about how requests reach you changes. There is nothing to install, it costs nothing, and you can switch pre-filling off on your form whenever you like.

Currently limited to Scotland.

  1. 1 Runway fills in your form

    When a repeat is due, the patient's Runway opens your existing repeat prescription page with their details already typed in.

  2. 2 The patient presses Submit

    On your site, as they do today. Runway never sends anything to you, and has no login, API key or plugin on your website.

  3. 3 Your protections all still apply

    CAPTCHA, rate limits, spam filters and form validation run exactly as they do for any visitor, because it is the patient submitting.
