The Diabetes App Built on 30 Years of Real-World Experience
Most diabetes apps want you to be perfect. They demand precise carb counts, exact measurements, and endless data entry. Then they judge you when real life doesn't fit their neat little boxes.
I got tired of that nonsense.
After three decades of living with type 1 diabetes, I built something different: an app that works with how people actually manage diabetes, not how textbooks say they should.
The Problem With Most Diabetes Apps
They're built by people who think diabetes management is a math problem. Calculate the carbs. Apply the ratio. Done.
Except it never works that way, does it?
What about the workout you did this morning? The stress from that meeting? The fact that yesterday's pasta behaved completely differently than today's? The pizza that spikes your blood sugar six hours later when you're asleep?
Traditional apps miss what actually matters: your patterns, your context, your real life.
What Makes Glysimi Different
Quick & Practical
Log a meal in 30 seconds. "Grilled chicken with salad" is enough. No PhD required.
Full-Day Context
See your entire day at a glance—meals, readings, notes, patterns. Not just isolated data points floating in space.
Pattern Recognition
Search your history. "Last time I had Thai food after yoga" becomes instantly visible. That's the experience that actually helps.
Built for Learning
The app gets smarter as you use it. Your patterns emerge. Your confidence grows. Your gut feelings get backed by real data.
How It Actually Works
Traditional Approach:
- Weigh everything
- Calculate precise carbs
- Apply formula
- Hope for the best
- Feel like a failure when it doesn't work
Glysimi Approach:
- Quick note: "Lasagna, medium portion"
- How'd it go? "Felt good, BS stable"
- Next time: Search "lasagna" → see what worked before
- Build confidence in YOUR patterns
Who It's For
If you're tired of:
- Apps that make you feel incompetent
- Spending 10 minutes entering one meal
- Perfect calculations that give imperfect results
- Not learning from your own experience
And you want:
- Quick, practical tracking
- To understand YOUR body's patterns
- Confidence in real-life decisions
- An app that respects your intelligence
Then Glysimi might be for you.
The Philosophy
After 30+ years with type 1 diabetes (and achieving time-in-range that most endocrinologists don't believe is possible), I learned something crucial:
Systematic experience beats theoretical perfection every single time.
That's why 50% of people with diabetes already rely on "gut feeling" over carb counting. They've figured out that precise calculations are too difficult and don't deliver results worth the effort. These are exactly the people I designed Glysimi for: Can we make that gut feeling even better, without adding too much overhead?
Get Started
The app is free to download and try. Available for iPhone.
Start building the kind of experience that actually works in real life. Your body is already teaching you—now you'll have a way to remember the lessons.
Glysimi was developed by Bo Frese, who has lived with type 1 diabetes for over 30 years and achieves time-in-range results that challenge conventional wisdom. Read more about My Personal Results: 30+ Years of Type 1 Diabetes
