How Eli helps

Eli app diary log — How was your day?

Daily tracking in seconds

Water, pain, wellness, and medication, all logged in a couple of taps, in language children actually understand. “How was your day?” instead of “complete your symptom assessment.” Connect a Fitbit or Apple Watch and Eli fills in what it can automatically.

Pain tracking built for children

Instead of clinical body charts, children tap where it hurts on their own friendly avatar, front and back, and add notes in their own words.

Patterns families can act on

Eli turns daily check-ins into clear reports covering pain frequency, location, and quality. Patterns surface early, and clinic conversations start from real data instead of memory.
