Your protein log. Your next appointment, better prepared.
Track protein and water quickly, keep weight and shot notes together, and bring a clear report to your next appointment. Built for GLP-1 routines. No account required.
Free daily logging. Optional Premium reports and longer trends.
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 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.
Why this one
One app for the whole thing.
Keep your protein, hydration, weight and shot notes in one simple diary. Protein Diary puts quick manual logging and a report you can bring to an appointment at the center of the experience.
Less, on purpose
Most food apps track everything. When your appetite is gone, that is friction, not help. Protein Diary tracks the few numbers that matter on a GLP-1 and stays quiet otherwise.
Food and shot, together
Log protein and hydration alongside your shot history, weight and side effects. Bring the records together in a report for your next appointment.
Yours, not theirs
Your diary is stored locally without a Protein Diary account or diary cloud-sync service. You choose what to export and share; device backups and optional services are explained in our privacy policy.
The part that matters most
No account. No diary sync. No ads. Your diary is stored locally.
What you log (food, weight, medication, side effects) is health data. The app does not automatically upload your diary to Protein Diary servers. You can choose to share records or send them to support. Read the full privacy policy for the details, including optional crash reporting, purchase services, exports and device backups.
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.
