About this app

Timer Door is a time tracker and timesheet for freelancers, contractors and students. Log work hours or study time with one tap, then turn billable hours into a PDF invoice. No account, no sign-up, no subscription, and your records stay on your phone.

Tap Start, Pause when you step away, End when you're done. This hours tracker counts only the time you really worked, so your timesheet and every invoice stay honest.

A TIME TRACKER BUILT FOR BILLABLE HOURS
• Track time per project, with every project under its client
• Set an hourly rate and watch earnings add up while the timer runs
• Mark sessions billable or non-billable: internal work hours count in your totals, never on an invoice
• Count to the second, or round each session up to the whole minute
• Work past midnight and the session splits across both days, so each day of your work log stays right
• Forgot to start? Add the entry by hand, with a note

POMODORO TIMER AND FOCUS MODE
• A Pomodoro timer inside the time tracker, so every focus block lands in your timesheet
• 25/5 blocks or your own lengths, with a ring that drains as the block runs down
• A break alert with sound and vibration, even when the app is closed
• Focus mode: the clock alone on pure black, easy on AMOLED screens

YOUR TIMESHEET, BUILT FOR YOU
• Week, then day, then session, with hours and earnings at every level
• Search notes, projects and clients, and filter by project or billable time
• Edit or delete any entry; an overlapping time is caught before it is saved

INVOICE MAKER FOR FREELANCERS
• Turn tracked time into a proper A4 PDF invoice in seconds
• Invoice numbers count up by themselves, and line descriptions are written for you
• Attach a day-by-day breakdown of every billable hour
• Issue the invoice in English or Arabic, whichever your client reads

INSIGHTS, FREE FOR EVERYONE
• Your time tracking turns into answers: best hours, busiest day, streak, this month against last
• Your best-paying client, charts by day, week, client and project, and a level that grows with every hour you track

STUDY TIMER, GOALS AND EXAM DATES
• Switch to Study mode for a study time tracker: subjects, topics and study sessions, with no money anywhere
• Daily and weekly goal rings, a goal per subject, a study streak and a month calendar
• Rate each study session and note what you got done
• Exam dates and project deadlines count down on Home, with a reminder on the day or up to a week before
• Record the result: your score out of the total, or whether the work went in on time, late or not at all

MADE FOR ANDROID
• Home-screen widget (Pro): today's hours and your goal, and start, pause or end the time tracker without opening the app
• A daily reminder at the time you choose, only on days with no work hours or study tracked yet
• Smooth and quick, compiled to native code, in English or right-to-left Arabic, light or dark

YOUR DATA STAYS YOURS
• A time tracker that keeps everything on your device; there is no Timer Door server
• No account and no sign-up
• Android's own device backup includes your records
