PinTrax: Dose & Vial Manager

Everything but the needle.

PinTrax manages the whole thing. Which site is next, how much is left in the vial, when your next dose is due, and what the syringe should read. Not just a log of what you already did.

Nothing leaves your phone.

Most health apps keep your injection history on their servers. PinTrax has no servers. There's no account, no sign-up, no sync, and no analytics. Your compounds, doses, notes and photos exist in one place, on your device, and there is no version of this app that can hand them to anyone. Not to us, not to a buyer, not to a court order. We built it so that isn't possible rather than promising not to.

A body map that knows where you've been.

Tap where you injected. PinTrax records the exact spot, not a vague label like "left thigh." Twenty-six zones per figure, front and back, feminine and masculine.

It warns you if you're placing a shot on top of a recent one. It shades the map by how heavily each area has been used. It suggests where to go next based on which sites have rested longest, and scores your rotation over your last ten injections so you can see whether you're actually spreading them out. If tapping a precise spot is difficult, you can log from a plain list of zone names instead.

Vials, pens and what's actually left in your inventory

Log a dose and the remaining amount updates. No separate counter to keep in sync, no drift. Vials show remaining in plain language. Pens are counted in doses, because "three of four left" is the thing you need to know, not milliliters.

Low warnings before you run out. Expiry warnings before dates pass. Private notes for source, batch and price, for your records only.

Reconstitution done properly

Vial amount, BAC water, desired dose, and the calculator gives you units on the syringe. U-100, U-50, U-40 and U-30. Reverse it to type syringe units and read back the dose.

Enter a CoA measured amount and it uses that. Enter purity and it derives the real content and shows its working. Blends get their own mode with several component templates, so you can see what a single draw delivers of everything in the vial.

Schedules that follow your plan

Daily, weekly, every few days, weekdays. Set the time and how far ahead to be reminded. Titration steps change your dose on the dates you choose, and reminders name the compound rather than saying "time for your injection."

Stock on hand

Track what's in the drawer. Reconstitute an item and stock drops when it's physically true, not guessed.

Journal and history

Notes, progress photos, and your own metrics like weight or waist. Chart them over time with markers where each compound started. Weekly recap with adherence and rotation. Full history, CSV export, and a shareable image that leaves your compound names out.

Also

Fingerprint or PIN lock. Full backup and restore to a file you control. Import from Shotsy.

Free for two compounds; PinTrax Pro unlocks your full stack.

Track everything. Share nothing.

PinTrax is a record-keeping tool for adults who already know what they're doing. It's not medical advice, it doesn't diagnose anything, and it won't tell you what to take. For that, talk to a doctor. 18+.
