How to choose a GLP-1 and peptide tracker

Seven questions worth asking of any app, ours included. Below each one is how PeptideUp answers it, so you can compare for yourself.

1. Who can see my data?

Look for where the data is stored and whether the app tracks you. Check its privacy label on the App Store.

PeptideUp: on your iPhone and in your own private iCloud. No account, no analytics on health data, no ad tracking.

2. Do I need an account?

An account means an email, a password and a company holding your health history.

PeptideUp: no account, ever. A new iPhone restores your history through iCloud.

3. Will it remind me, and can I log without opening it?

The best reminder is the one you can act on in one tap.

PeptideUp: reminders on dose day and a Home Screen widget with "Mark as taken" and 15 minutes of Undo.

4. Does it know my vials and pens?

Mixed vials keep for a limited time and pens run out. A tracker should count what is left from the numbers on your label.

PeptideUp: a Cold Vault with a 28-day clock for mixed vials, doses left, a warning three days before, and what your supply costs a month. It keeps the numbers you were given; it never works out a dose.

5. Does it help me rotate injection sites?

PeptideUp: a site rotation compass for belly, thighs and arms, with the next spot ready every dose and how each one felt.

6. Is the AI honest about what it is?

An assistant should answer from your own logs, show you before it writes anything, and never suggest a dose.

PeptideUp: Ask Pengu answers from your logs, shows a card before logging anything, and sends dose questions to your prescriber.

7. Can I bring it to my prescriber?

PeptideUp: a one-page summary of your last 12 weeks: weight trend, doses logged against your schedule, the dose steps you logged and the side effects you noted. A PDF you can share or print.

PeptideUp is a tracker, not medical advice. It never recommends a medicine, a dose or a schedule.
