Stop working for free
Pro Lucro turns the hours you already worked into an invoice. No timer to forget to start.
Built for how people actually log work
Most time trackers assume you'll remember to press start.
This one doesn't. Open the calendar, tap a day, and write down what you did — this morning, yesterday, or last Tuesday. When the month's work is on the page, turn it into an invoice.
Time, the way you remember it
A month at a glance with your worked days marked. Tap any day to add hours, an activity and a note. Travel bills at its own rate. Time you don't charge for still appears on the invoice, at zero.
Costs you paid for them
Log a reimbursement with a photo of the receipt. It lands on the same invoice as your time, listed separately. Sales tax can apply to your time alone or to the whole invoice.
Invoices that look like yours
Three templates, your accent color, your logo, your choice of type. Numbering that picks up where you left off. Share the PDF by mail, message, or anything else on your phone.
The part your client actually sees
Every invoice carries your business details, your tax registration number if you have one, and a clear line for every hour and every cost. Reissue an old one, and the figures, rates, and client details come back exactly as they went out.
Pay once
Your first invoice is free. After that, unlocking invoicing is a one-time purchase — not a subscription, with nothing to renew and nothing to cancel.
Tracking time, managing clients, logging reimbursements, reports, and backups never need it.
Nothing leaves your phone
No account. No sign-up. No servers. The app has no analytics, no tracking, and no third-party code of any kind — it makes no network requests at all.
The App Store privacy label reads "Data Not Collected" and means it.
What it doesn't do
No syncing between devices yet. A backup file moves your records to a new phone, and syncing is planned.
iPhone only, portrait only.
Not for teams. No roles, no admin, no seats.
Made for one person first
Pro Lucro was built for one interior designer who bills by the hour, and it ran their real client work for months before it was offered to anyone else.
