Dossi learns how sleep, exercise, meals, stress, and 50+ factors affect your insulin needs—then adjusts delivery automatically.
Blood sugar is shaped by dozens of factors—meal composition, sleep quality, stress, exercise, hormones, illness, even time of day. But current insulin pumps only see two inputs: carbs and glucose. They don't know you slept badly, had a high-fat snack, or just went for a run.
Not just what happened, but why.
Reads glucose every 5 minutes via Dexcom Bluetooth. Syncs sleep, exercise, and heart rate from Apple HealthKit—no manual logging.
A Bayesian engine learns your individual patterns across sleep quality, infusion site age, dawn phenomenon, exercise, and caffeine.
Models glucose trajectories 4 hours ahead. Quantifies uncertainty. Adjusts insulin delivery in real time through closed-loop control.
Snap a photo of your meal and Dossi identifies the food, estimates macros, and predicts glucose impact—replacing manual carb counting.
After every meal, Dossi tracks what actually happened and refines its understanding of your unique physiology.
Today's automated systems—Omnipod 5, Control-IQ, the 780G—already close the loop well. They adjust basal and correct highs from your CGM. Dossi does that too, then goes further: it reads the context behind your glucose.

Modern pumps offer manual exercise and sleep modes you switch on. Dossi instead learns these effects from your Apple Health data and applies them automatically.








Dossi continuously projects where your glucose is heading and steers delivery to keep the curve in range—through meals, exercise, and overnight. The lighter line is your glucose; the accent line is the path Dossi is steering toward.
Not if-then rules—a real optimizer. Every 5 minutes Dossi searches for the basal schedule that best keeps you in range over the coming window, weighing lows twice as heavily as highs so it leans safe when it leans.
Dossi watches whether your glucose actually falls as fast as your insulin predicts. When you're running resistant or sensitive, it re-estimates your sensitivity on a rolling basis and blends that into every correction.
Your insulin sensitivity and carb ratio aren't constants. Dossi learns yours from your own outcomes—by time of day, pod-site age, and exercise—only after 10+ clean observations, and always clamped to a safe 0.6–1.6× band.
When you're stuck high with insulin already on board, Dossi steps basal up in blocks to bring you down—and backs off the instant glucose starts falling or insulin-on-board is doing the work.
Pizza isn't oatmeal. Dossi classifies each meal by fat, protein, and fiber—and learns how that shape absorbs for you, modeling the delayed, drawn-out spikes that catch carb-only systems off guard.
Manual, Auto-Adjust, or fully Adaptive—plus Conservative, Standard, or Aggressive correction strength. You decide how much Dossi automates and how hard it pushes. Most pumps lock you into one behavior.
