Sugar: Glucose Logger
Growing up with GSD 1 made blood sugar logging personal. Sugar is my way of making that everyday task feel a little lighter.

A lighter way to log blood sugar
I grew up with GSD 1. When I was younger, I watched my parents manually log my blood sugar readings for me. Before logging was something I had to think about doing myself, it was something they were doing for me.
As I got older, I struggled with simply wanting to log. Knowing that a record matters doesn't make you want to stop and create one. Sometimes I just wanted to get the reading down and move on with my day.
I wanted logging to ask less of me. That's where Sugar started.
Looking back at my parents doing that work, and then feeling the friction myself, made this a problem I wanted to build for. The question was personal: how could I make recording a reading easier to follow through on, even when I didn't feel like doing it?
A Chris Raroque video about Amy, the AI calorie tracker, gave me inspiration for the interaction. What if I could log blood sugar the way I'd jot down a note or say something out loud? The video helped shape the input. Growing up with GSD 1 gave me the reason to build it.
In Sugar, a note like ‘102 oatmeal and coffee’ carries both the reading and its context. The app parses it, saves it, and keeps the history organized. Type it or say it, then get on with your day. That is the experience I wanted for myself.
Designing with intention.
I designed the entry around the part I struggled with: getting myself to log in the first place. Plain-language input and voice logging let a reading begin as a thought, rather than a series of fields to fill out.
Context still matters. Notes about food, exercise, or the moment around a reading can sit alongside the number. Quick tags for fasting, before meals, after meals, and bedtime add structure without requiring a longer entry every time.
Watching my parents log for me also shaped how I think about the record after it's saved. A reading can be something you come back to or share with someone involved in your care. History and export belong in that experience, alongside making the initial entry easier.
Sugar is a logging and informational tool. My focus is on making readings easier to record, organize, and review, with room for people to choose their units and target range.
From idea to interaction.
Type it. Or say it.
Log a reading in plain language or by voice, with notes about the moment around it.
Keep the context.
Tag readings as fasting, before meals, after meals, or bedtime, and set reminders to log.
See your history.
Review charts, 30-day averages, and patterns in your recorded glucose readings.
Connect with Apple Health.
Import existing readings and save new ones back to Apple Health. Import is available with Pro.
Make it yours.
Choose mg/dL or mmol/L, set a target range, and customize the theme.
Keep records close.
Sync readings across devices and export your history to share with family or your healthcare provider.
Looking back. Moving forward.
Sugar connects two parts of my life: growing up with GSD 1 and learning to build products. My parents did the manual logging for me when I was younger. Now I can put my engineering into making that task a little simpler.
My own reluctance to log is what I keep coming back to. A feature can look good on a screen, but the question I care about is whether it makes the next entry feel easier to make. That's the standard I want to keep building toward.
