Who is Pinwell for?

Adults on a self-administered injection regimen — GLP-1 (semaglutide, tirzepatide, retatrutide), peptides (BPC-157, TB-500, etc.), or testosterone replacement therapy. If you pin yourself or supervise someone who does, Pinwell is for you.

Do I need an account?

No. There's nothing to sign up for. Open the app and you're in. The only login Pinwell ever uses is your iCloud account, and only if you turn sync on.

How do I add my first medication?

Tap the amber + on the logbook screen. The first dose entry asks you to add a medication — pick a category, write the name, set the half-life and default dose, save. Then pin the dose.

What if I'm new to peptides?

Pinwell tracks; it doesn't prescribe. Always work from a real clinician's protocol — your endocrinologist, primary care, GLP-1 telehealth provider, or TRT clinic. Pinwell is the logbook you bring to your follow-up, not a replacement for one.

Why are the injection sites where they are?

Pinwell maps to the ten clinically recommended subcutaneous and intramuscular sites: anterolateral thigh, upper-outer glute, shoulder cap (deltoid), and four abdominal quadrants. We deliberately avoid the inner thigh near the femoral artery — credibility, not convenience.

What does "next suggested site" mean?

The logbook scans your past 14 days, scores each site by how recently it was used, and suggests the coolest one — biased toward sites you've actually used before. The body diagram's amber heat-map is the visual version of the same scoring.

Can I edit or delete a logged dose?

Yes. Tap any row in the logbook history — the detail sheet lets you change every field or delete the entry (with a confirmation). The streak and rotation recalculate automatically.

What if I forget to log a dose for a day?

Open the entry sheet and roll the time back — Pinwell lets you backdate freely. The streak counts days with at least one log, so it survives a late entry. Same-day duplicates are fine; they all show up.

Where does the half-life data come from?

You set it. Pinwell ships with placeholder defaults when you add a known medication, but the half-life field is editable per compound — pull the number from your protocol or a primary source you trust. Pinwell's job is to do the math given a half-life, not to publish one.

Is the level chart "medical-grade"?

No. It's a deterministic one-compartment model fed by your own log — useful for spotting whether you're rising, plateauing, or trough-ing relative to your dosing pattern. It is not a serum concentration measurement. The chart screen labels itself Educational reference only. Not medical advice.

What does the reconstitution calculator do?

Given a vial size in mg and a volume of bacteriostatic water added, plus your target dose in mg, it tells you how many units to draw on a U-100 insulin syringe. Always free, always offline.

Can I see a 30-day or 90-day chart?

Yes — the level chart has 7-day, 30-day, and 90-day toggles. The 7-day default makes the sawtooth pattern of typical peptide regimens easy to read.

What is and isn't behind the Pro paywall?

Free, forever: dose log, body diagram, level chart, reconstitution math, streak, calendar. Pro ($39 lifetime): unlimited medications (free tier is capped at one), iCloud sync, family sharing, every future feature.

How do I restore a previous purchase?

On a new device, open Settings inside Pinwell, tap the paywall card, then tap Restore previous purchase. Apple checks your Apple ID for the lifetime entitlement and flips you to Pro.

Does Family Sharing work?

Yes. Pinwell's lifetime unlock is a Family-Sharing-eligible non-consumable IAP — one purchase covers up to five Family Sharing members at no extra cost.

How do I turn on iCloud sync?

Settings → toggle iCloud sync on. Pinwell uses your Apple ID's private CloudKit container — encrypted, end-to-end if you have Apple's Advanced Data Protection enabled. We never see the data.
