No account, no ads, and it works fully offline. Free to start, with a Pro upgrade when you need unlimited invoices.

  • A one-tap timer for any client at their hourly rate, plus manual time entry for work done away from your phone.
  • Unlimited clients and projects, each with their own rate.
  • Turn a client's unbilled hours into itemized invoice lines automatically.
  • Add fixed fees and expenses, then apply tax and discounts.
  • Clean, professional PDF invoices you can share by email, messaging, or anything else.
  • Mark invoices sent or paid and see exactly what is still outstanding.
  • Round tracked time to the nearest 6, 15, or 30 minutes when you bill that way.
  • Full local backup and restore, so moving to a new phone loses nothing.

Time tracking and full data backup are never locked behind Pro. Prices are set in Google Play and shown in your local currency; billing is handled by Google Play, so we never see your payment details.

Privacy by design

Your clients and rates never leave your phone.

Hourbook makes no network calls and collects nothing about you. Your clients, time, and invoices live in an on-device database, and only leave your phone if you choose to share an invoice or a backup file yourself.
