The parts nobody sees

Four things that make it hard. One way of handling them.

Problem 1

Alarms aren’t management.

Phone alarms ring, get snoozed and forget. They don’t know if you took it.

MyAddi logs each dose in one tap, follows when you actually woke, and notices kindly when one’s late.

If it gets worseSave My Life is one hold away
Problem 2

Sick days are guesswork have a plan.

You’re meant to change your doses exactly when you’re least able to think.

Sick-day mode follows the rules your team gave you, and Save My Life is one hold away.

Problem 3

“How have you been?” I don’t know.

Ten minutes with your doctor, and a month to remember.

Quick check-ins become patterns, and a plain A4 report your GP or endocrinologist can use.

Problem 4

Worrying from a distance without hovering.

The people who love you worry. Constant texting doesn’t help.

Your family see you’re okay at a glance, and hear straight away if Save My Life starts.

A day with MyAddi

Built around your day, not a clinic’s.

06:45
You wake up flat.

A one-minute check-in: sleep, energy, mood. Your sleep comes from Apple Health.

12:00
The dose that always slips.

It remembers so you don’t have to, and tells you kindly if it’s late.

15:00
The dip.

Tap what you feel. MyAddi Smart turns it into a pattern, not a guess.

17:00
Coming down with something.

Turn on sick-day mode and your doses follow your team’s plan.

22:30
You get to stop thinking about it.

Tomorrow’s first dose is ready, and your family can see today went fine.

Save My Life

If you can’t speak, MyAddi speaks for you.

One hold starts a calm plan anyone can follow, even if they’ve never heard of Addison’s. After beta, your card or wristband does it with one tap.

Why MyAddi exists
