## What is Cairnwell?

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.

PRIVACY YOU CONTROL

Everything stays on your device. No account, no login, no cloud.
Your health data is never sold, never used for advertising, and never transmitted.
Export everything to CSV for free, any time.
Delete all of your data from inside the app.

FREE AND PREMIUM

Cairnwell is free to use. Log unlimited injections, keep your full medication history, track your weight, and export your data at no cost. Premium adds unlimited medications, your full analytics history beyond the last 30 days, clinician PDF reports, a one-file backup, and weekly observations about your own patterns.

Premium is $4.99 per month or $34.99 per year, with a seven-day free trial on the annual plan. Payment is charged to your Apple ID account. Subscriptions renew automatically unless canceled at least 24 hours before the current period ends. Manage or cancel any time in your App Store account settings.

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.

## Version history (last 2 releases)

### 1.4 — 2026-10-10

Your body measurements, on one chart.

• Progress now charts every body measurement you record — waist, hips, chest, neck, thighs, and arms — together on one chart, with body fat alongside on the same timeline
• Left and right are drawn as a pair, so both sides are easy to tell apart
• Entered something by mistake? Open Entries from the Weight or Body measurements card to review your history and delete any entry
• Deleting an entry imported from Apple Health removes it from Cairnwell only — it stays in Apple Health and is not imported again
• The weekly strength-workout insight now counts strength sessions only, not walks or runs imported from Apple Health

Your health data stays on your device. No account. No ads. No analytics.

### 1.3 — 2026-09-30

No release notes.
