Don't come out skinny-fat.
On a GLP-1, up to ~40% of what you lose can be muscle. Peptimist gives you a personalized protein target — so you lose the fat and keep your strength.
The core app is totally free — no account, no catch. AI extras $2.99/mo after a 7-day trial. Your data stays on your device.

Why Peptimist exists
Peptimist exists to help the GLP-1 community come out of this healthier and stronger — not to squeeze people while they're working on themselves. That's the whole idea, and every decision in the app follows from it.
It's why the core app is totally free: everyone deserves the tools, so the protein target, logging, shots, and weight tracking cost nothing. The small AI subscription is there because AI genuinely costs us money to run — the fee covers that.
And it's why there are no ads, no selling your data, and no account to create. Everything you log stays editable, because it's your data, not ours.
We're on your side. That's the whole business model.
Come out strong.
