Everything a printed code should be able to do
Once a code is on a menu, a box, or a billboard, reprinting is the expensive part. Dynamic links move the decisions into your account instead.
Per-scan analytics
ProEvery scan recorded with approximate city, device, OS, and time, exportable to CSV. Free plans keep aggregate counts by day, device, and country.
Repoint any time
FreeChange where a printed code goes in seconds. 3 links free with unlimited scans; unlimited links on Pro.
Your domain on the code
ProScanners see your name, not ours, with custom endings you choose instead of a random slug.
A file behind the code
ProHost a PDF or image at the code itself and swap the file without reprinting. Menus, spec sheets, price lists.
replaced, same code
Smart routing
ProOne code, many destinations: route each scan by country, language, device platform, or time of day.
Link pages
ProA hosted page of up to 12 link buttons behind one code, editable any time. One QR for everything you do.
Made in your browser
Static codes are generated entirely on your device. Nothing is uploaded unless you create a dynamic link or host a file, and we say exactly what those store.
No scan-count paywall
Free dynamic links have unlimited scans and no expiry. A code you printed keeps working; we do not hold it hostage.
Data you can erase
Free plans keep aggregate counts only. Pro per-scan records are kept about 90 days, and you can export or delete them at any time.

How an event QR code works
An event QR code carries a standard iCalendar event (the same format calendar invitations use) with the title, start and end time, location, and description inside the image. Scanning it offers to add the event to the phone's calendar in a couple of taps. No typing dates on a poster, no "I'll add it later" that never happens.
Put one on wedding invitations, conference badges and session signage, concert and league posters, open-house flyers, school newsletters, anywhere the difference between "saw it" and "calendared it" matters.
Filling in the fields
Title and start time are required; end time, location, and description are optional. The all-day checkbox switches the event to a date (or date range) without times, right for festivals, deadlines, and holidays. Keep the description brief: it's the field that bloats the code fastest, and the scanability tag in the Studio will tell you when it's getting dense.
One timezone caveat
The times you enter are encoded as local "wall-clock" times, and each phone interprets them in its own timezone. For a physical event that's exactly what you want: 7 PM on the poster means 7 PM at the venue. For a virtual event with attendees across timezones, state the timezone in the title or description ("Webinar: 3 PM Eastern") so nobody guesses. And like every printed QR code it's static: if the event moves, reprint.
Frequently asked questions
Which calendar apps does it work with?
Any app registered to handle calendar events: Apple Calendar on iOS and Google Calendar on Android cover nearly everyone. The payload is standard iCalendar, the same format email invitations use.
How are timezones handled?
Times are encoded as local wall-clock times and each phone reads them in its own timezone. Perfect for in-person events; for virtual events with a spread-out audience, name the timezone in the title or description.
Can I make an all-day event?
Yes, tick the all-day checkbox and the event is encoded as a date (or date range) without times, which calendars display as an all-day banner.
Can I update the event after printing?
No, the details live inside the image, so a printed code is fixed. If details might change, encode a URL to an event page you control instead, and update the page.
Is my event information uploaded anywhere?
No. The code is generated entirely in your browser; the event details are never uploaded and are only stored if you sign in and explicitly save the code.
