01
Every tool assumes you eat meals
Pumps, apps, and carb counters are all built around three discrete meals a day. Most T1Ds don't eat that way.
02
IOB doesn't account for grazing
Your pump reduces its recommendation because it sees active insulin — but it doesn't know that insulin is already spoken for.
03
Carb counting is less accurate than you think
Peer-reviewed research finds T1D carb estimates are off by ~21% on average — and 63% of meals are underestimated. Your CGM sees what your count misses.
04
Works with any pump
Omnipod, Tandem, Medtronic — Graze connects to your Dexcom and works alongside whatever pump you use.
