Retain: GLP-1 Muscle & Protein

Retain is a protein and strength notebook for people taking a GLP-1 medicine. Log your meals, lifts, weigh-ins, lean-mass entries, side effects and the medication history you enter, and Retain counts each week for you: how many days you reached your protein floor, and how many times you lifted. It describes your own logs. It never measures muscle, grades your body or tells you what to take.

TODAY: A DIAL FOR YOUR PROTEIN FLOOR
Set your own goal in grams per kilogram and Retain works out the grams a day. The dial counts down what's left, the "Log protein" button takes a number in two taps, and the meals you eat most sit underneath as one-tap chips. On a low-appetite day, that's the whole job.

MUSCLE SIGNALS
Three counts from your entries: days at your floor this week, lifting sessions against the weekly target you chose, and the change in your lean-mass entries next to the change in your weigh-ins over the same dates. Nothing is estimated.

LOG FOOD YOUR WAY
• Type a meal, or just the grams of protein.
• Read a nutrition label on your device.
• Scan a barcode; only the digits are used for an optional product lookup.
• Say "Log protein in Retain" to Siri, or add it to Shortcuts or the Action button.

STRENGTH, WEIGHT AND LEAN MASS
Log working sets and follow the estimated one-rep max for each lift, set only against your own earlier sessions. Weigh-ins show a trend with a noise band, so one salty morning doesn't read as a setback.

ONE PAGE FOR YOUR APPOINTMENT
Retain Pro builds a one-page PDF from the last 30, 60 or 90 days: protein days, meals, weigh-ins, lean-mass entries, lifts, side effects and dose dates, plus up to six questions you want to ask. It's made on your iPhone and goes only where you send it.

YOUR MEDICATION HISTORY
Record the medication, dates, status, injection site and side effects you choose. Retain shows your history only. It never recommends a dose, a time or a next site. Learn cards open plain-language pages on glp1base.com about the medicine you logged.

PRIVATE BY DEFAULT
Your logs stay on your iPhone. App Lock, a private app-switcher cover, and export or import of a complete archive are built in. No account is needed unless you want cloud photo scanning.

RETAIN PRO, ONCE OR BY PLAN
Lifetime is a single purchase that unlocks every Pro feature that runs on your iPhone: the appointment summary, twelve weeks of muscle signals, the timeline, lean mass beside weight, the plateau page, the come-off habit checklist and floor check-ins. It never renews.
Monthly and yearly plans include all of that plus cloud plate-photo scanning, which returns editable calorie and macro ranges with a confidence level (up to 10 scans a day). The App Store shows your local price and any trial before you buy. Restore purchases any time.
