The glucose wave. Every T1D rides it, up and down, all day.

Life with T1D, minus some of the mental load

Guides that skip the lecture, a packing checklist that has met airport security, and a reminder app on the way. No dose advice, no ad trackers. Built by someone who counts carbs too.

Traveler Toolkit

Tell it how long you're going and it builds your packing list: backup insulin, the 2x rule, docs for security. Print it, save it, done.

Build your list

The app (soon)

Prebolus reminders, retrospective CGM insights, and a travel mode. See what's coming and grab a spot in line.

Preview the app

The reminder app T1Ds keep asking for

Not another bolus calculator. A nudge to prebolus before meals, quiet insights from your CGM history, and less alarm noise, not more. It'll never tell you how much to take. That's between you and your care team.
