Questions.
Is the app iPhone only?
Yes: Cardr is an iPhone app, with an Apple Watch app that shows your code and the people you met. It needs iOS 18 or later (watchOS 11 or later on the Watch). Apple’s on-device model files your note on iPhones with Apple Intelligence, and built-in rules file it on others.
I use Android. Can I use Cardr?
Your card works on cardr.co: make it on the web, share its QR code and link, and add it to Google Wallet. The app itself is iPhone only. The people you meet need nothing on any phone.
Is the app free?
Yes. Your card, scanning, voice notes, your people, Insights, your first written follow-up and a reminder for your first person are free, for good. Pro writes the follow-up and reminds you for everyone you meet; new subscribers get a free trial, and the app shows its length, the price and the charge date before you start.
Is my data synced with cardr.co?
Once you sign in, yes. Sign in with the same email you use on cardr.co and your card and the people you met are there; people you add in the app appear on the web too. You can start without an account, and everything stays on your iPhone until you sign in.
Does Cardr send messages for me?
No. Cardr writes the follow-up and reminds you; you change what you like and send it from your own email, Messages or WhatsApp. The one email Cardr can send for you is the optional thank-you to people who send you their details.
Is anything I say recorded?
No. Your words become text on your iPhone and no audio is kept. Scanned cards are read on your iPhone too, and no image leaves it.
