How it works
Three taps from shelf to honest total.
Scan the price tag
Aim your camera at the number on the shelf. No typing.
We add local tax & convert
Prisio applies the state or province sales tax, then your exchange rate.
See the real price in your money
One clear total — what you'll actually pay at the register.
Why Prisio
Built for honest prices and zero surprises.
Everything that matters when you're shopping somewhere new — and nothing you didn't ask for.

US & CA sales tax
State and province rates, added so the total is real.
Scan history
Pro saves every scan so you can compare as you go.
Multi-language
Use Prisio in your language — English, Svenska, Deutsch, Français.
The breakdown
Every number, nothing hidden.
An example: that $79.99 US price tag isn't what you pay. Prisio shows the math the shelf leaves out — tax in, then converted to your money.
Approximate — local fees may apply. Rates and tax are estimates to help you decide, not a receipt.
Free & Pro
Start free. Go Pro once.
Conversion and tax are free for everyone. Pro removes the limit and works offline — a single one-time purchase.
Shown for your region. The App Store always displays your exact local price before you buy.
Private by design
Your trip is nobody else's business.
Everything runs on-device
Scanning, tax and conversion all happen on your iPhone.
No account, no sign-up
Open the app and scan. There's nothing to log into.
No tracking, no analytics
We don't collect, sell, or share anything about you.
Nothing leaves your phone.
No servers. No cookies. No data brokers. Prisio works because your iPhone is fast enough to do the math itself — so the only place your scans live is with you.
