Capabilities
Everything in one place
Four tabs and nothing you have to learn. Everything below is in the app today — all of it free except the reconstitution calculator, which is what Pro unlocks.
My Vials
Know how many shots are left
Every vial you're tracking, with its remaining shots counted down as you log against it. Add, edit, or retire a vial in a couple of taps.
Schedule
Your routine in one view
What you take, how often, and when — the whole protocol laid out and editable, so the schedule is a thing you can see instead of remember.
Rotation
Every dose tagged to a site
An anatomical body map covering eight sites across front and back. Pick where the shot went as you log it and your rotation history builds itself.
Weight
Watch the trend, not the day
Log your weight and read it back as a trend line with your recent entries. Weeks of data beat a single morning on the scale.
Side effects
Log how it actually felt
Record side effects and mood alongside the dose that preceded them, so what you felt and when is written down rather than reconstructed later.
Week in review
A snapshot you can share
Doses logged, current streak, total medication, average mood, top injection site, and weight change — one week summarised, ready to share.
Peptide 101
A walkthrough for your first vial
Gather supplies, draw your dose, inject safely — a beginner guide with a worked example, plus cited medical sources for everything stated.
Calculator
Reconstitution math, donePro
Pick your syringe, choose a preset or enter your own numbers, and get the draw amount. This is the feature Pinmate Pro unlocks.
02
Reconstitution
Do the math once
A unit converter that runs the arithmetic on the numbers you type in. It takes your vial amount, your diluent volume, and your dose, and returns the syringe volume that corresponds to them.
It does not suggest, validate, or recommend any amount — it only converts what you enter. Every figure is yours to verify with your provider.
In the app this is the one feature Pinmate Pro unlocks. It runs free right here, so you can put your own numbers through it before deciding whether to pay.
- 01Enter the compound amount in the vial
- 02Enter the bacteriostatic water you added
- 03Enter the dose you were prescribed
- 04Read the corresponding syringe volume

Site rotation
Your history, mapped
Every dose you log is tagged to a site. The map shows which of the eight you used last and how recently — a record of where you've been, not a recommendation of where to go.
- A Eight sites — left and right arm, abdomen, thigh, and glute, across front and back views.
- B Recency shading — recently used sites stay tinted so your last rotation is visible at a glance.
- C Tap to log — pick the site as you record the dose. Two taps, done.

Reference library
Nineteen compounds, preloaded
Each entry ships with its half-life and typical dosing interval so the app can chart what you log. Pinmate does not supply, source, sell, or recommend any compound — you add what you already have.
| Compound | Also known as | Half-life | Interval | Class |
|---|
Half-life values are published pharmacokinetic reference figures used for charting only — not dosing guidance.

Questions
Before you ask
Is Pinmate medical advice?
No. Pinmate is a passive tracker and calculator. It does not prescribe, recommend, diagnose, or treat. It records information you enter and does arithmetic on numbers you provide. It is not a medical device and has not been evaluated by the FDA or any regulator. Always verify your dose, timing, and protocol with a qualified healthcare professional.
Does Pinmate sell or source any compound?
No. Pinmate does not sell, source, refer, endorse, or otherwise facilitate obtaining any compound or medication. You add what you already lawfully possess, and you are responsible for using any tracked substance lawfully in your jurisdiction.
Where is my data stored?
On your device. In v1 all health data — doses, injection sites, side-effect notes, weight, and calculator inputs — stays local. There is no account and no sync. The only data that leaves the app is subscription status and an anonymous purchase identifier, handled by RevenueCat so that Pro can unlock.
Do I need an account?
No. There is no sign-up, login, or email required to use the app. Install it, accept the first-launch disclaimer, and everything is immediately available.
Who is Pinmate for?
Adults 18 and older who are already self-managing their own injectable regimens — peptides, GLP-1, TRT, or hormone therapy — and want one organized place to keep the record. There is a mandatory 18+ age gate on first launch.
Which platforms is Pinmate on?
Pinmate is on iPhone via the App Store and requires iOS 15.1 or later. An Android version is in the works — leave your email above and we'll send one message when it's ready.
