Attendance that can't be faked, without tracking your people.

What every check-in proves

The server decides every check-in, and the phone never gets to say what time it is or which office it is in.

• The right place

  The phone is on the office's Wi-Fi router or internet address, or inside its area on the map, as each office chooses.

• The right phone

  Apple App Attest or Google Play Integrity shows it is a genuine app on the one phone linked to this person.

• The right person

  Face ID or a fingerprint unlocks a key held in the phone's secure hardware, for each check-in.

• The right moment

  The server's own time and a single-use challenge mean a check-in can't be replayed or back-dated.

What OneTap never does

• No location trail

  OneTap keeps no location history and no coordinates of people.

• No biometrics

  Face ID and fingerprints stay on the phone, and OneTap receives only a signature.

• No selling of data

  OneTap doesn't sell data, use it for advertising or profile your people.

Two parts, for the people who use them

• The OneTap app, for employees

  Join from an email invite, link one phone, and check in and out with one tap on iPhone or Android.

• OneTap Admin, for companies

  Set up offices, invite people, see who is in, review doubtful check-ins, and export attendance and statutory registers.
