What it does
One-tap insulin & BG logging
Log AM and PM shots with dose buttons in units, and as many BG readings a day as you take. Weight (kg or lb), appetite, water, urination, vomiting and notes too — plus reminders for shots, meds and vet visits.
BG curves with your target band
See each day's BG curve on a 24-hour chart with min, average and max. Enter the target range you agreed with your vet and it appears as a shaded band — the app never suggests a range of its own.
Trends and lab results
Daily BG range and average over time, weight trends, and fructosamine, clinic BG and ALT from vet visits — with photos of the lab reports.
A report your vet can read in seconds
A 30- or 90-day PDF: a day-by-day table of weight, AM/PM insulin units, BG readings, appetite and vomiting, plus your lab results. Show it at the clinic, share it or print it.
Free, forever: every logging feature, reminders, and charts for the last 14 days. Premium (optional subscription, 7-day free trial on the yearly plan) adds 30- and 90-day charts, the vet-ready PDF export (your first PDF is free) and more than one cat. Your data stays on your device. Log BG in mg/dL or mmol/L.
Diabetes Notes is a record-keeping tool. It does not diagnose, treat or give veterinary advice, and never suggests insulin doses or BG targets. Please follow your veterinarian's instructions.
