We're looking for T1Ds
who will tell us when something is wrong.

Glysimi is in beta. It works — it's been used daily by its creator for over six years — but it hasn't been tested by hundreds of people with different lives and routines.

iPhone only · iOS 26+ required · Android is not supported

Who we're looking for

The most useful beta testers for Glysimi share a few things:

  • You manage by feel, not formula. You've been living with T1D long enough to have built up intuition about your body. You've probably tried systematic tracking at some point and decided the overhead wasn't worth it.
  • You've tried other apps and given up. You know exactly where they broke down for you — too slow, too complex, too focused on data for your doctor rather than decisions for you. That experience makes you a sharp evaluator.
  • You check your glucose multiple times a day. Glysimi is designed for people who are actively engaged in their daily management — whether that's a CGM or finger-prick. The more decisions you're making, the more useful the app becomes.
  • You're willing to be honest. Not politely positive. Actually honest. If something is confusing, slow, missing, or just doesn't feel right, we want to know specifically. Vague positive feedback is the least useful thing you can give us.

You don't need to be technically sophisticated. You don't need perfect control. You don't need to eat any particular diet. You just need to be managing your diabetes actively and willing to pay attention.

What you'll be testing

THE DIARY

Chronological log

Log glucose readings, insulin doses, meals, notes, activity, how you feel. Tag-based, searchable, instant to enter.

Does the 30-second logging habit actually form?

SEARCH

Find any day in your history

Type what you're looking for. Returns full-day context, not isolated entries. The feature that changes how you manage.

Does the search surface useful patterns?

REMINDERS

Follow-up nudges

Triggered by what you log: after a meal, after a correction, after a low. You choose which events matter and how long to wait. All local — nothing sent to any server.

Do they fire at the right time, or get ignored?

Coming soon: Automatic CGM import via Apple Health

What beta testing means — honestly

This is not a polished, complete app. Some things will be rough. Some things will be missing. Some things may behave unexpectedly.

You will not lose your data — the storage layer is stable and has been in daily use for years. But the interface, the onboarding, the reminder logic, and various other aspects are actively being refined based on feedback from people like you.

What we're asking for: use it daily for at least two weeks. Log your real decisions. Then tell us what worked and what didn't. Not in a form — in a real message to a real person who built the app.

Beta spots are limited and manually reviewed. This isn't gatekeeping for its own sake — it's because the most useful feedback comes from a small group of engaged users, not a large group of passive installs.

STEP 3

Install Glysimi

Once your invitation arrives, tap the link in the email to install Glysimi through TestFlight. That's it — you're in.

The whole process takes about five minutes.

A note on timing

We are in the early stages of beta testing, so it may take a while before you receive an invitation. If you received a confirmation email after signing up, your registration was successful — you're in the queue. We appreciate your patience.

We prioritise testers who can provide thoughtful, specific feedback and who will actively use the app. If you use accessibility features like VoiceOver or larger text, we especially value that perspective.
