Never guess
a dose or a
day again.
Did I already do today? Which vial was that from? How much is left? Three seconds of doubt, every single time — and the answer lives in your head, where it does not belong. It takes longer to wonder than to look it up.

Every shot, every dose,
measured & remembered.
Four things, one place — instead of a notes app, a calculator, and a second notes app for the food.
See it working.
Real screens from the app, walked through one at a time. No install, no account.
Did I already do today?
The question that makes people open a notes app at 6am and still not be sure. Here it is answered before you finish asking it — and the answer keeps itself, because logging takes one tap in the moment rather than a reconstruction that evening.
Open it and the answer is already on screen: what is due, when the last one was, how many this week, and which vials are still in play. No menu to go through first.
Which one is open, and how much is left?
Three in the fridge and no memory of which was mixed when. Each one here knows what it was reconstituted at, what is left in it and how many shots that still buys — and every pin you log comes out of the right one, so the bottle in your hand and the number on screen never drift apart.
What did I actually eat?
Photograph the plate and the calories and protein are in — no weighing, no scrolling a database for “chicken, cooked”. Protein first, because that is the number that matters on a course, with an honest range rather than false precision. Five photos are free for good.
What is the half-life on this?
Eighty-odd entries with published half-lives and how each is stored, so a protocol can be planned against numbers instead of forum memory. The same reference is in the app and on this site — information only, and it names nothing you can buy here.
Open the referenceHow it
works.
Set up the schedule.
Name it, pick how often, and note the planned dose. Reminders follow the schedule, so a missed day is obvious rather than something you have to notice.
Log the shot.
Which vial it came from, the site, and how it felt. The vial depletes as you log, so what is left in the fridge is always a number rather than a guess.
Watch the curve.
Logged doses are laid over a first-order decay model built from published half-lives. It shows where your log puts you today — a picture of your own history, not advice.
Photograph the plate.
Calories, protein, carbs and fat without typing, against a protein target derived from your own height, weight and activity.

Common
questions.
Does pinning tell me what to take?
No, and it is built so it cannot. It records what you did and does the arithmetic you would otherwise do on paper. There is no recommendation engine, and the reference section carries no dosing protocols.
Is it a medical device?
No. It is a logbook. It does not diagnose, treat or monitor anything, and it is not a substitute for talking to a prescriber.
Where does my data live?
In the EU — Frankfurt, on Supabase and Vercel. Nothing is sold, there are no advertising identifiers and no cross-app tracking. Deleting your account is one tap in the app and erases everything immediately; the full JSON export lives in Settings on this website, under the same login, and is free.
Does the app track what I do in it?
Only if you say so. Usage events and crash reports are off by default and stay off until you turn on "Share usage data" in Settings. Even then we send event names like app_opened or pin_logged tied to your user id — never a compound, a dose, a note, a meal or a photo. Because an event saying you logged an injection is health data, that switch is a separate explicit consent under Art. 9(2)(a) GDPR, and flipping it back off stops the sending at once.
What happens to my meal photos?
They are stored in your own private folder and sent once to Anthropic, in the US, to estimate the calories — under standard contractual clauses, and not used to train models. Nothing else in the app is sent anywhere for analysis, and manual meal entry never leaves the EU.
Who am I actually buying from?
Apple. Subscriptions and scan packs are In-App Purchases, so Apple is the seller of record and handles payment, invoices, cancellation and refunds through your Apple ID. We are your counterpart for the service itself. Cancelling a subscription happens in iOS Settings, not by deleting the app.
Do I need an account?
Yes — it is what lets the same log open on a second device, and what makes export and deletion possible at all.
Android?
Not yet. iOS first, properly, rather than two apps done half-way.
