## What is IsoCalc?

IsoCalc keeps your isotretinoin treatment under control. Enter your weight, daily dose and the goal set by your doctor, and the app does the math every day.

YOUR TREATMENT AT A GLANCE
• Cumulative dose so far in mg and mg/kg, with a clear progress ring
• Daily dose per kilogram of body weight
• Remaining dose, days left and the expected end date
• Goal as a cumulative dose (for example 120 to 150 mg/kg) or as a number of months
• Earlier dosing periods and previous courses count towards the total

PHOTO DIARY
Take progress photos of your skin and see how it changes over the weeks.

REMINDERS
Never miss a dose, a blood test or a dermatologist visit. Daily, weekly, monthly and more.

ISOCALC PREMIUM
• No ads
• PDF report for your doctor with all doses and dates
• Before and after photo comparison

SAFE AND SYNCED
