Draw-first doses
Today leads with the units on your syringe, with mg, mL and the syringe size underneath. No digging through settings.
Free on iPhone, with optional Pro
Your dose, at a glance.
Your data, on your phone.
Vialist Log is the peptide, GLP-1 and TRT tracker that shows the number you actually draw, counts your vials down to the day, and never asks for an account.

- No tracking

Privacy you can verify
Most trackers want an account. Vialist doesn't even have a server.
What you log stays on your iPhone. No sign-up, no cloud copy, no ad SDKs. Apple's App Store label for Vialist reads "Data Not Collected", and that is the whole story.

Built for real protocols
Everything you run, the way you run it.
Titration steps
1 mg, then 2 mg, then 4 mg. Vialist moves you up on your date, or asks first, and shows each step's draw.
Several doses a day
Twice or three times daily, each time with its own reminder and its own log. Add an instruction line to any protocol.
Vials, counted down
Every vial's remaining amount at a glance. Pro adds the runs-out forecast and an order plan for the next 4, 8 or 12 weeks.
Record a loss
Syringe failed or spilled? Take it out of stock without counting it as a dose. Your schedule stays honest.
Blends, sprays, pens
Multi-compound vials, nasal sprays by the spray, pens and oral doses, all with the right math.
Injection site rotation
Tap the site on a front and back body map: abdomen, love handles, thigh and shoulder on the front; back of arm, hip and glute on the back. See how recently you used each.
Doses next to results
Weight, waist, blood pressure, sleep and labs charted alongside your doses. Pro adds step bands and estimated levels.
Doctor report Pro
Preview the report in the app, then share the PDF or print it. Made on your phone and sent only where you choose. You pick what goes in.
Widget and lock screen Pro
The next dose, the time and the draw on your home screen and lock screen.
Apple Health import Pro
Read your weight, sleep and heart data from Apple Health and see it next to your protocols. Read only.
Vial labels Pro
Print a label with a QR code. Scan it when you log to pick the right vial. The code holds only an ID.
Reminders
Local reminders for each dose time, low stock and the end of a cycle. No push server, nothing sent.
Export and backup
Export your log as CSV or JSON. JSON backups are encrypted with a password you choose.
Private by design
Face ID or passcode lock, Hide names for a discreet view, and reminders that never name a compound.
A look inside
Real screens, real numbers.
Captured from the app itself. The doses shown are sample data, not advice.

Math that never guesses
Cross‑checked by an independent model.
Vialist's stock and calculation logic is tested against a separate Python model written from first principles, then compared number for number. When an input is missing, Vialist shows your mg and tells you what is missing. It never invents a number.

0doses ever suggested
Free, no account
Do the math right here.
Enter your own vial, water and dose to see the units to draw. It converts the numbers you type; it never suggests a dose. Want it in your pocket with reminders? That's Vialist Log.

Questions
Straight answers.
Is my data really only on my phone?
Yes. Vialist has no account system and no server for your log. Backups are files you create and keep, in your own iCloud Drive or Files.
Does Vialist tell me what dose to take?
No. You enter the dose you and your provider decided on. Vialist does the unit math and keeps the record.
What does it cost?
The core app is free, with up to 2 active protocols. Vialist Pro is $4.99 per month, $29.99 per year with a 7-day free trial, or $59.99 once (US prices). See pricing.
Does it need an internet connection?
No. Everything you log, every calculation and every reminder works offline. The app itself makes no network requests of its own: purchases go through Apple's StoreKit, and links you tap, such as cited sources, Terms and Privacy, open in Safari.
Will I be reminded before the free trial ends?
Yes. When you start the 7-day trial, Vialist can schedule one local notification for day 5, two days before it ends, if you have allowed notifications. It never asks for permission just for this. You can also cancel any time in iPhone Settings, under your name, then Subscriptions.
Can I lock it or hide the names?
Yes, and both are free. Turn on the Face ID or passcode lock, use Hide names to show short stand-ins in the app, and switch on discreet reminders so notifications never name a compound.
Android?
iPhone first. Android is planned.
