Cairnwell is a private, on-device record keeper for people prescribed a GLP-1 medication by their own doctor. It brings your injections, weight, symptoms, nutrition, and strength into one timeline, so you stay consistent and walk into every appointment prepared.
A cairn is the stone marker showing a hiker the trail is still underfoot. Cairnwell plays the same role across a long course of medication.
WHAT YOU CAN RECORD
Injections and doses. Log a shot in seconds, note your injection site, and keep a full history of every dose change your prescriber makes.
Weight and measurements. Chart your weight, waist, and body measurements over any date range.
Symptoms. Note side effects and how strong they felt, then see how they line up with your injection days.
Daily check-in. Rate hunger, energy, cravings, and mood in under 30 seconds.
Protein, fiber, and water. Fast entry against targets you set yourself.
Strength and activity. Keep a light workout log and import steps, weight, and workouts from Apple Health (read-only).
CLINICIAN-READY REPORTS
Generate a clean PDF for any date range and bring it to your next visit. Your medication timeline, symptom log, weight trend, and the questions you want to ask land on one document your provider can read in a minute.
WORKS WITH ANY GLP-1 PRESCRIPTION
Cairnwell works with brand, generic, and compounded medications, entered exactly as printed on your label. It is independent of every pharmacy, manufacturer, and prescribing service, so your record stays yours even when your prescription changes.

WHAT CAIRNWELL IS - AND IS NOT
Cairnwell records and organizes. It does not diagnose any condition, prescribe or recommend any medication, calculate, convert, or suggest doses, interpret your results, or give medical advice. It is not a medical device. It is a personal journal and record-keeping tool for adults 18 and older, not a substitute for your doctor or pharmacist. Follow the instructions that came with your prescription and talk to your clinician before making any medical decision.
