Billable Hours Calculator Downloads & RevenueBillable Hours Calculator · App Store

Billable Hours Calculator turns raw project time into an accurate bill —
automatically.

Whether you're a freelancer, consultant, contractor, or anyone who bills by
the hour, this app removes the guesswork and spreadsheet math from tracking
what you're owed.

TIME IT TWO WAYS
• Start a live timer the moment you begin working — pause and resume anytime,
and it stays accurate even if you switch apps or lock your phone.
• Forgot to start the timer? Log a session manually down to the exact minute,
backdated to any date and time, with an optional note.

YOUR BILLING RULES, YOUR WAY
• Set a rate per block (e.g. $50 per 15 minutes) for each project.
• Choose per-session rounding, where every session rounds up individually, or
cumulative rounding, where your total raw minutes are summed first and
rounded once.
• Add an optional flat setup fee per project.
• Set a minimum fee that automatically kicks in if a project's logged time
falls under your floor.

STAY ORGANIZED ACROSS CLIENTS
• Color-code every project so you can tell clients apart at a glance.
• See a running total the moment you log time, with a clear line-by-line
breakdown of exactly how it was calculated.
• Every session — timed or manual — is listed with its duration, date, and
note, so you always have a record to back up your invoice.

BUILT FOR HOW YOU WORK
• Light and Dark mode, matched to your system or set manually.
• No account, no login, no subscription required to track your time.

Billable Hours Calculator doesn't try to be an all-in-one invoicing suite —
it does one thing precisely: turns your logged time into the number you
should be charging, exactly the way your contract says it should be
calculated.
