About
Retain is a calm GLP-1 journal for protein, strength, meals, weight, lean mass, symptoms, and the medication history you enter. It helps you understand the habits and trends you logged without claiming to measure or guarantee muscle retention.
PROTEIN, STRENGTH, AND WEIGHT—TOGETHER
Log meals manually, track protein and fiber, record resistance sessions and sets, and view strength alongside weight and lean-mass entries. Retain describes your data; it does not grade your body or turn a chart into a medical conclusion.
THREE WAYS TO LOG FOOD
• Enter a meal manually.
• Read a nutrition label on your device.
• Scan a barcode; only the detected digits are used for optional product lookup.
Retain Pro adds plate-photo estimates. After sign-in and explicit consent, a meal photo returns editable calorie and macro ranges with a confidence cue—not a fake-precise answer. Check every estimate before saving.
A CALM MEDICATION HISTORY
Record the medication, dose, date, status, injection site, and symptoms you choose. Retain shows your history only. It never recommends a dose, injection time, or next site.
ONE TIMELINE
Review meals, weight, lean mass, strength, symptoms, dose, and site logs in context. Plateau and maintenance modules provide general education and observe-only checklists without telling you to change treatment.
PRIVATE, PORTABLE RECORDS
Progress photos use a neutral date-based timeline, never a before-and-after judgment. Export and import a complete versioned archive of your live records, including progress photos; the app labels the file sensitive and excludes demo and deleted records. Delete your account and local data in the app.
RETAIN PRO
Retain Pro includes ongoing plate-photo macro ranges and the timeline, plateau, and maintenance modules. Monthly and annual options are available; the App Store shows your local price and any trial eligibility before purchase. Restore purchases any time.

Retain is a tracking and education tool, not a medical device. It does not provide medical advice, diagnosis, dosing, or treatment. Always follow your prescriber's instructions, and talk with a qualified clinician before changing medication, nutrition, supplements, or exercise.

What's New in Retain
2.3.0
July 28, 2026
Small, honest fixes to the Retain Pro screen: • If subscription plans can't be loaded, Retain now tells you what actually happened instead of blaming your connection. • "Try again" visibly checks with the App Store and reports back — including when plans are still unavailable. • After a retry succeeds, your plan is preselected so subscribing stays one tap. • The sample-data tour no longer surfaces raw App Store errors.
