BE READY AT 9:40

Riverside Medical, 2nd floor
The senior side
The best interface for an 82-year-old is almost no interface.
Your parent's phone shows one thing: what is happening today, when to be ready, who is taking them, and where. There is nothing to learn, nothing to sign into, and nothing they can get wrong.
Marlow asks zero effort from the person being cared for. That is not a nice-to-have — it is the condition on which the whole product works. Anything that requires them to act is something that will not happen.
The rules this side is built on
Six decisions, and none of them are negotiable.
No login. Not once a month, not ever.
Their phone is paired to the circle one time, by scanning a code on your screen. After that it simply shows their day. There is no password to forget and no screen they can get lost on.
A list, never a grid.
Calendar grids are a spatial puzzle. A list of what is happening today, in order, is not. Today first, then later today, then tomorrow — and a sentence at the end telling them that is everything.
Single tap, no gestures.
Nothing is hidden behind a swipe, a long press, or a pinch. Icons always come with words next to them, because an icon on its own is a guess.
Large type that gets larger.
Text starts at 20px and follows the phone's own text-size setting up to double that. The layout is built to survive it rather than break.
Their language, not yours.
English, Spanish, Chinese, Hindi and French. The appointment is entered once, by whoever is organizing, and read by your parent in the language they actually think in.
They cannot break anything.
Their account is granted read access at the database and nothing more. It is not that the edit buttons are hidden — it is that the server would refuse the change. Nobody has to worry about Dad accidentally deleting Tuesday.
The signature moment
"Be ready at 9:40" is doing more work than it looks like.
A calendar says the appointment is at 10:15. That is a fact about a clinic, not an instruction to a person. Marlow works backward — the drive, the traffic, a buffer that respects somebody who does not move quickly — and shows the only number that matters to them.
The same care goes into the ride home. Their card counts down to the end of the appointment, not to some earlier moment a driver needs to set off, because telling somebody to be ready half an hour before their appointment finishes is thirty minutes of standing in a corridor.
And when nobody has claimed the ride yet, they are not told that. They are told Marlow is arranging it. It is true, it is not alarming, and it is not their problem to fix.
Getting them set up
You do the setting up. They hold the phone still.
You open Marlow, show them a square on your screen, and point their camera at it. That is the whole of it — no email address, no password, no verification code read out over the phone. The code stops working the moment it has been used, and you can turn the pairing off from your side at any time.
If the camera is fiddly, there is a ten-character code they can type instead. Both doors lead to the same place.
See it on a phone that matters to you.
Marlow is piloting with a small number of families. If you have a parent and a group chat full of logistics, that is exactly who it was built for.
