Shipped, and considering.
There are no dates here on purpose. QuorumPony is built by one person around a day job, so things ship when they're right rather than when a calendar says so. Here's where everything stands.
Split and recover
Real Shamir Secret Sharing over GF(2^8): turn a secret into a set of cards with any threshold you choose, and recover from any few by scanning a QR code or typing a printed code.
Check a card
Confirm a stored card is intact and which backup it belongs to, without rebuilding or revealing the secret.
Printable PDF cards
Export the whole set to a clean PDF to print, store apart, or hand to people you trust.
Fully offline, open core
No account, no sync, no server, and a cryptographic core published under Apache-2.0 so the math can be read and verified.
On-device safety
Biometric lock, automatic clipboard clearing, and a screen that hides the secret when the app goes to the background.
Six languages
English, Spanish, German, French, Japanese, and Portuguese (Brazil), switchable any time inside the app.
More ways in and out
Additional formats for the secret you split and the cards you export, as long as each one stays fully offline and doesn't drag a server or an account into the picture.
An Android version
QuorumPony is iPhone-only today. An Android port is the kind of thing the family has done before, but it is not promised on a timeline.
More languages
Six today. More are welcome, especially with help from people who speak them.
