Track every GLP-1, peptide, and TRT dose with the warmth of a paper ledger and the precision of a clinical-grade tracker. Local-first, no subscription, $39 lifetime.
Most trackers feel like spreadsheets. Pinwell feels like an apothecary's logbook — and it does the math a clinic would.
Each pin warms a circle on the figure. The brighter the amber, the more recently the site was used. Glance at the diagram, rotate to a cool zone, and your tissue stays healthy.
Pinwell models each compound's half-life and graphs the accumulation curve from your actual log. See where you are on the curve — rising, steady, or falling — before your next pin.
Pinwell looks like a logbook because it is one. Everything below works on every screen, on day one. No tiers, no nudges, no upsell screens between you and your data.
Per-compound half-life modeling. See your accumulation curve from your actual log — not a generic textbook graph.
Pick the med, drop the time, tap the site on a real body diagram. The form remembers your defaults so a daily log feels like signing your name, not filling a form.
U-100 insulin syringe math, drawn like a 19th-century apothecary's instruction card. Always free.
Tally-mark streak, ink-dot calendar. Glanceable consistency without the dopamine theater of a habit app.
Up to five family members on one lifetime unlock. Pay once, share with the people you actually trust.
Run GLP-1 + peptide + TRT side-by-side. The free tier holds one med; Pro removes the cap.
One transaction. Yours forever. No renewals, no resub prompts, no surprises.
Your data syncs between your iPhone, iPad, and (soon) Apple Watch via your own iCloud private database. Apple can't read it. Neither can we.
No subscription. No renewal. No upsell prompts between pins.
