Buy it once, no subscription. Both sides of a bilingual card stay on one contact, and every card is read entirely on your iPhone — we have no server.
Three months later, all you have is "the machinery guy from Nangang". The card is still there; the person isn't.
Kardhaus is for the version of you three months from now.
Buy it once. No subscription. Scanning is free and unlimited forever, and recognition runs entirely on your iPhone.
■ You forget the name. You remember the room.
The card map puts everyone back where you met them. Or just type "the machine-tool person I met in Taichung last month" — it works out the filters itself.
■ An impression only you can see
"She handles purchasing, quote due September." That is never printed on a card, and three months later it is the only thing that saves you. Hold the mic and say one line — speech becomes text on the device and the audio is never stored.
■ The fields a card actually carries
A LINE ID gets its own field with an Add Friend button beside it. So do a tax number, a phone extension, a licence number, and a Japanese card's name reading. None of it gets dumped into a notes field you can search but cannot tap.
■ One photo, every field
Cropped, straightened, compressed — then the words on the card go into the right fields. Chinese and Latin names, job title, department, company, phone, email, address, and the professional credentials a doctor's or a lawyer's card is mostly made of.
■ Both sides, one contact
Scan the front and the back of a bilingual card in one go and they stay on a single card. Swipe to see the back; fields from both are read in together.
■ Your data leaves whenever you want
Free vCard and CSV export — nothing to unlock. Imports accept vCard, CSV, and card photos, and you get to check the column mapping before anything is written.
■ Cards will not fill up your photo library
Card photos live in Kardhaus's own database and are never written to your camera roll. It works the other way too: Kardhaus has no permission to read your library.
■ iCloud sync
Cards live in your own private iCloud database and follow you to a new phone. We have no server and cannot see your cards.
■ What people ask before installing
Is this a subscription?
No. One payment, no auto-renewal, and it works with Family Sharing.
What stays free?
Scanning, with no limit on cards. Every field, tags, notes, search, import and export, plus 50 AI recognitions. The one-time purchase lifts the cap on AI recognition and adds natural-language search, the card map and relationship records.
Does it work offline?
Yes. Recognition runs on the device, so it works on a plane and in a basement exhibition hall.
Where do my cards go?
Onto this phone, and into your own private iCloud database if you switch iCloud on. There is no account, no login and no server of ours, so we cannot see your cards.
Can I get my data out?
vCard and CSV export, free, always, with nothing to unlock. Anything that reads vCard or CSV will take them.
Will cards fill up my photo library?
No, and that is deliberate. Card photos live in Kardhaus's own database and are never written to your camera roll. Kardhaus also has no permission to read your library.
Do I need to sign up?
No. Open it and it works.
Kardhaus is a one-time purchase. No subscription, no auto-renewal, yours for good, and it works with Family Sharing.

This app has not received enough ratings or reviews to display an overview.
• Vertical cards scan now. Portrait or landscape, the four edges are found the same way.
• A QR code printed on the card always reaches the fields. It used to be missed entirely on some cards — especially faintly printed ones, where the code was readable but the text was not.
• Adding another card of your own can start from the camera or your photo library, instead of a blank form.
• The camera's bottom controls are easier to hit, and Done no longer gets pushed off-screen while you are shooting a batch.
• Auto-shutter reads hand shake more reliably, so it is less likely to fire mid-wobble.
