iPhone
Aiming a phone at a small code is harder than it looks for some. Freeman teaches that one movement, patiently, on its own practice codes. Nothing real is ever started.
Freeman was 83. He had type 1 diabetes, and he could not reliably aim his iPhone at the small code on a Dexcom™ sensor applicator. The task is difficult to understand for him. The target is over there. The camera is on the far side of the phone. The picture is on the near side. And the hands have to move the phone in the direction that brings one into the other. Any link in that chain can break on its own.
This app is named in his memory, and it does one thing: it practices that movement.
It is designed to be used by diabetic patients along with their carers. It was eye-opening for me to realize that, for some, these simple code-scanning procedures were really difficult.
PRACTICE, NEVER THE REAL THING in a SAFE ENVIRONMENT (Not a real sensor activation).
Freeman has its own practice codes, and recognizes nothing else. Point it at a real sensor and nothing happens — the app is built so that it cannot succeed on anything but its own material. It does not start, activate, configure, control or communicate with any sensor, and it has no Bluetooth, no network connection and no health data of any kind. There is nothing here that can be set off by accident.
Every practice session begins with a reminder that this is practice, and ends with a sentence that says so again: "Practice complete. No sensor was started."
BUILT FOR HANDS THAT SHAKE, AND EYES THAT TIRE
• Spoken guidance, slowed down, in your own language and accent where the voice exists
• One instruction at a time, held long enough to act on
• Buttons that light up and pause before they do anything, so you can see which one you pressed
• Very large tap targets, and a second tap while a button is confirming is ignored rather than queued
• Haptics for three moments only — found it, framing is good, finished — because a constantly buzzing phone is one more thing to fight
• Nothing anywhere tells you that you got it wrong
3 THINGS TO PRINT
A sheet to tape to a wall, where the target holds still and aiming is the only variable. A target you hold, at the angle you would really meet one. And a cut-out practice label, clearly marked, for an applicator that has already been used and finished with. Print them, or send them to whoever is helping.
They are a ladder rather than a menu — start at the wall.
FOR THE PERSON HELPING
Freeman is often installed by somebody else: a partner, a daughter, a carer. It is free, it has no account, no sign-up, no advertising and no analytics. It stores nothing at all — no history, no results, no pictures. Close the app and there is no record that anyone practiced, because a record of somebody's declining dexterity is not a thing this app is willing to keep.
