## What is Vialmetry?

Vialmetry is a private logbook for the vials you already have. Record what is in each vial, convert your own numbers into syringe units, log each injection and rotate your sites. Your log stays on your device, works offline and needs no account.

BUILT AROUND THE VIAL
• Record each vial's strength, the water you added, the date it was mixed, its beyond-use window and what it cost.
• See what remains as you log, with every vial kept separate.
• Add an optional lot number, source, storage note and comments.

ARITHMETIC YOU CAN CHECK
• Enter the vial strength, the water you added and the amount you have already decided on. Vialmetry converts it into a syringe mark and shows the concentration, volume and units on screen.
• Work backwards from a mark you can read to the water to add.
• Every input and unit stays visible, so you can check the working by hand.
• Vialmetry never suggests what or how much to take.

LOG AND ROTATE
• Log an injection in a few taps: amount, time, site and notes.
• A front and back body map shows which subcutaneous sites have rested, based on the rest period you set.
• Note soreness, redness or other site reactions.
• Edit, skip or delete entries. Each vial's remaining amount stays in step with your history.

SCHEDULES AND REMINDERS
• Record the schedule you follow: daily, every few days, weekly or on chosen weekdays, with optional on and off weeks.
• Optional reminders are scheduled by your phone. By default the lock screen shows only "Scheduled reminder".

COST
• Keep what each vial cost alongside your log and see your spending over time.

SUMMARY AND EXPORT
• Create a printable summary to share with your healthcare provider.
• Export your history as a spreadsheet, or a complete backup file, at any time.

PRIVATE BY DESIGN
• Local-first. Your log lives on your device.
• No ads, no analytics, no tracking.
• Optional Face ID or biometric app lock.
• Optional private cloud copy for moving your log between your own devices. It is created only when you tap Save to cloud, and you can delete your account in the app at any time.

MADE TO BE CALM
• Three palettes, light and dark appearance, and a clear, uncluttered layout.

IMPORTANT
Vialmetry is for personal tracking and educational purposes only. It is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. It does not provide medical advice, diagnosis or treatment. It does not recommend medications, doses or schedules, and it does not determine whether any dose is appropriate. Calculations only convert the numbers you enter; check them yourself. Always consult a licensed healthcare provider. The presence of a substance name in the app is not an endorsement and does not mean the substance is approved for human use.
