The protein‑first food diary, built for GLP‑1.
Log a meal in two taps. Protein in grams front and center — plus weight, shots, and side effects, all in one quiet, private diary.
Free to use. No account required. No ads, ever.
What it does
Three things, done properly.
When appetite is low, every bite counts. Protein Diary keeps the focus on the numbers that matter and stays out of your way.
Protein in grams
Not points, not percentages — grams, the way your targets are actually written. Two taps to log a meal, a 310-item protein-forward food library, and daily goals with streaks.
Weight, shots & side effects
A weight log with trends, a simple shot log with reminders, and quick side-effect tags. Everything recorded exactly as you enter it — the app never suggests doses or schedules.
A report for your doctor
One tap builds a clean PDF of your food, weight, shot, and side-effect history — made to bring to your next appointment, so the conversation starts from real data.
Discreet by design: the app is called Protein Diary on your home screen, and reminders never mention medication details on your lock screen.
The part that matters most
No account. No cloud. No ads. Your data never leaves your phone.
What you log — food, weight, medication, side effects — is health data, and we built the app so we never see it. There are no Protein Diary servers holding your diary. Read the full privacy policy for the details, including how optional crash reporting will work if we add it.
Pricing
Logging is free. Forever.
The core diary will never be paywalled — and neither will your own data. Premium adds depth for people who want longer trends and richer reports.
