Large numbers. High contrast. No squinting required.

Every diabetes app is built for Type 1.
90% of diabetics are Type 2.

If you're Type 2, you don't need an insulin calculator. You don't need CGM integration. You don't need bolus ratios or carb databases with 40,000 entries.

You need to log a number. See if it's trending up or down. Show your doctor at your next appointment.

That's it. That's the whole app. And it shouldn't make you feel stupid for not understanding features you were never going to use.

It shouldn't take longer to log your reading than to take it.

Frequently Asked Questions

How much does it cost?
$4.99 one-time purchase. No subscriptions, no in-app purchases, no ads. Pay once, use it forever. Every feature is included from day one.
What units does it use?
Both mg/dL and mmol/L. Toggle between them in settings. The app converts and displays your readings in whichever unit you prefer.
Does it estimate A1C?
Yes. Based on your logged readings, the app calculates an estimated A1C. It's not a replacement for a blood test, but it gives you a useful ongoing estimate between lab visits.
Can I export for my doctor?
Yes. One tap generates a clean, doctor-ready PDF with all your readings, averages, and trends. No paywall, no premium tier. It's included.
Is my data private?
Your data is stored on your device and in your personal iCloud account. We never see it, store it, or send it to third-party servers.
Do I need a CGM?
No. This app is designed for people who check their blood sugar with a finger-stick meter and log manually. No CGM integration needed or required.
What devices does it work on?
iPhone, iPad, and Apple Watch. Requires iOS 17 or later, which supports iPhones and iPads from 2018 onwards.
Other apps: $84/year
