Glysimi app showing diary entries with the text: Almost ready for beta testing

Finally, a diabetes diary that actually works

Most apps just collect your numbers. Glysimi helps you build the kind of practical knowledge that matters when you're deciding how much insulin to take.

Track Everything

Blood sugar, insulin, food, and life—all in one clear view. No endless scrolling, no confusion.

Find Patterns Instantly

Type "pizza workout" and see every similar day. Your experience becomes searchable knowledge.

Make Better Decisions

The best diabetes tool isn't an algorithm. It's your own experience, organized and accessible.

Go beyond carb counting

For many, systematic carb counting is a burden. Glysimi helps you train your 'gut feeling' by making your own experience searchable.

Train your intuition

Instead of relying on rigid rules, Glysimi helps you build confidence in your own judgment. By quickly searching for past experiences, you can make better-informed decisions in the moment. Learn more about this approach.

Why Glysimi hits different

Built for real people managing real diabetes, not just collecting data points.

Search that actually finds things

Type "pizza workout" and instantly see every time you had pizza then exercised. No endless scrolling through your history.

See your whole day at a glance

Blood sugar, insulin, food, notes, and tags—all in one clear, readable view. Everything you need, nothing you don't.

Built for real eyes

Large, readable text and high-contrast colors. Designed for daily use, tested by someone who checks glucose 10+ times a day.

Fully supports iOS accessibility

Including VoiceOver and Dynamic Type for larger text sizes. Health data should be accessible to everyone.

Your data stays yours

Everything lives on your device. Export anytime. No account required. Your health data is too important to share.

Works with Health app

Seamlessly integrates with Apple Health. Import your CGM data and export your logs.

Built by someone who lives this daily

30+ years of experience, distilled into one app

After 30+ years with Type 1 diabetes, I couldn't find an app that worked for my real needs. Everything had tiny text, search that didn't work, or made simple things complicated.

So I built Glysimi for myself—and used it to achieve 90%+ time-in-range over the past 5 years.

Now I'm sharing it because I know you've faced the same frustrations. This isn't a product built by a tech company. It's a tool built by someone who uses it every single day.
