What it does

Amber, not guilt

A dose you did not log gets a Resolve button. No streaks, no percentages, no red.

Quiet by design

Nobody sees the name

Hide names in the app, on reminders, and on the Lock Screen. A dose notification only says a dose is due.

Questions

FAQ

Do I need an account?

No. There is no account, no server, and nothing leaves your phone. Your log lives on the device. Back it up to a file you keep, and restore adds what is missing without overwriting anything.

Does it tell me what dose to take?

Never. VialBook is a tracking tool. It shows the numbers you typed and the history you logged. Your doctor decides your dose. The injection site is a suggestion based on what you used last, not a prescription.

What does it cost?

Free covers one medicine and the last 30 days of history. Pro is $3.99 a month or $28.99 a year, with a 7-day free trial. Backup and export are always free.

What happens to my data if I stop paying?

Nothing is deleted. Older history shows as a locked row until you come back, extra medicines are paused rather than removed, and you can export everything at any time.

Which medicines work?

Anything you take on a schedule or as needed: GLP-1 pens and vials, TRT vials and pens, pills, and more. Doses can be mg, mcg, or syringe units, with any custom value.

Can I hide the medicine name?

Yes. Hide names swaps the name for a neutral label in the app, on reminders, and on the Lock Screen, so a dose notification only says a dose is due.

What if I miss a dose?

It shows in amber with a Resolve button. There are no streaks, no percentages, and no red guilt screens. You can add, edit, or backdate any past day without losing history.

Is there an Android version?

Not right now. VialBook is built natively for iPhone.
