Kern keeps your work logbook and your certificates in one place, signed and in date. It is built for job sites with no signal: your logbook works offline and syncs when you are back in range, and your certificates stay on your phone, ready to show without a connection. It was built first for rope access, and for anyone whose hours are logged, signed off and checked against a certificate.

• Log work offline. Entries are written on the device and queue for sync, so a job site with no coverage never costs you a record.
• Keep your certifications with you. Your cards are stored on the device and readable without a connection.
• Log once against more than one scheme. An entry records what the work was; each scheme reads it by its own rules.
• Share deliberately. Show a certification to an employer or a client, and see afterwards who looked.
• Get hours signed off. A supervisor countersigns an entry on the spot.

Kern is an independent product. It is not affiliated with, endorsed by, or sponsored by IRATA International, SPRAT, or any other certification body, training provider, or employer. It is not a certification body: it does not issue, award, assess, or validate any certification, and a record kept in the app is not itself a qualification.

Certification bodies appear in the app as reference entries we created, so that you have something to record your work against. They are not those bodies' accounts: none of them has joined, and none has reviewed or approved anything here. The app labels every one of them and lets them act in no one's name.

Unless a certification was issued through the app by the body that awards it, it is a record the holder entered themselves — and the app says so on every screen that shows one.
