For travelers

Go anywhere. Pack twice, worry half.

Travel with T1D is mostly a logistics game, and logistics can be systematized. Double supplies, split between bags. Documentation for security. A plan for keeping insulin cool. Once the checklist is handled, the trip is just a trip.

The Toolkit below builds that checklist for you. The guides cover the parts a list can't: time zones, security lines, and what to do when things go sideways far from home.

What's here for you

  • The Traveler Toolkit: a packing checklist built around your trip
  • Time-zone concepts explained, so you can plan with your care team
  • Flying with insulin: security, storage, and backups
  • The 2x rule and why every seasoned T1D traveler swears by it

Traveler Toolkit

Tell it your trip length and it drafts your packing list: supplies doubled, documents listed, cooling covered. Check things off, add your own, print it or save it.

When insulin costs more than you have

The emergency option most people do not know exists, the $35 programs, and where to start looking. Links to the programs themselves, because only they can tell you what you qualify for.

The app is out

Version one is on the App Store: prebolus nudges, carbs off a barcode, and your CGM history read from Apple Health. iPhone only, no account, free, and it never tells you how much insulin to take.
