iPhone · iOS 18 and later · coming soon
Two sides. One person. Obviously.
A business card scanner for iPhone that works offline, needs no account, and is bought once instead of rented. It reads the Chinese side and the English side of the same card as one contact — because that is what they are.
100 free scans, front and back included
Buy it once
US$5.99 at launch, one time, forever. No monthly fee, no annual fee, no ads on any tier. The price rises in stages and we say so up front — whatever you paid, you own.
Works with the network off
Recognition runs on your device using the OCR built into iOS. Turn on airplane mode and scan a card — it works. That is the whole product, not a degraded fallback mode.
One card, two faces
It asks for the back before you put the card down, then reasons over both faces at once. Chinese and English names both kept. Switchboard and direct line correctly typed, not duplicated.

100 free scans, front and back included
Kardhaus is in development for iOS 18 and later. Leave your email and you get the TestFlight build when it opens, plus 100 free AI scans on the house — double-sided cards included, counted as one card, not two.
What this is not
- Not a digital or NFC card you hand out — this reads the paper you were given.
- Not a CRM, and not a team-shared vault. It is one person’s filing cabinet.
- Not a social network. Nobody is notified that you scanned their card.
- Not free-with-ads. There are no ads on any tier, including the free one.
Where we are still honest about the gaps
There is no Android version yet, no web app, no macOS app, and no CRM integration beyond CSV export. If several colleagues need to work from one shared card pool, a cloud product is the right tool and we will not pretend otherwise.
Guides that do not need us
Your iPhone can already read a business card with nothing installed. These explain how, and where the built-in tools genuinely stop being enough.
