Every machine has a story. Keep the record.

Less admin between services.
New in 1.0.4: practical shortcuts for the records you keep most often.
Log Again
The same service, a fresh record.

Log Service
From reminder to service record.
Open a service draft from a maintenance reminder. Save the work you completed and mark that reminder done in the same step.

What can I do for free?
Track up to two machines, keep service records and notes, set reminders, and export your records as CSV. Kelvik Pro adds unlimited machines, private iCloud sync, advanced insights, and Ownership Packet exports.
Do I need an account?
No Kelvik login is needed to start your personal logbook. Optional iCloud sync uses your Apple account. Shared Garage uses an anonymous device identity rather than a username and password.
Can I use Kelvik offline?
Your personal logbook is stored on your device, so you can view and update local records without an internet connection. Syncing with iCloud or Shared Garage requires a connection.
How does iCloud sync work?
With Kelvik Pro, your personal records can sync through your private iCloud account across your Apple devices. Shared Garage is a separate, optional way to share selected machines with other people.
Can I export my records?
Yes. Export a CSV from Settings to use in Numbers, Excel, or another spreadsheet app. Pro adds an Ownership Packet ZIP with a readable PDF summary, records, and attached photos, receipts, and documents.
How do I get Kelvik Pro?
Download Kelvik free from the App Store, then choose a monthly or annual subscription inside the app. Apple handles payment. You can manage or cancel your subscription in your Apple account settings.
