About this app

Chrona is a simple, good-looking time tracker for freelancers, students and anyone who wants to know where their hours go.

Start the clock when you begin, stop it when you're done. Chrona keeps track of the rest.

TRACK IN ONE TAP
• Start a timer with a description, project, tags and a billable flag
• Restart recent work instantly; suggestions narrow down as you type
• Continue any past entry with one tap, or swipe it to the right
• Keep an eye on the running timer from your notifications, and stop it from there

FIX YOUR DAY AFTER THE FACT
• Add time you forgot to track, with exact start and end times
• See every day as a calendar of colour-coded blocks
• Tap an empty slot in the calendar to fill it in
• Swipe an entry away to delete it, with undo if you change your mind

SEE WHERE YOUR TIME WENT
• Weekly, monthly and yearly reports
• Total time, billable hours, daily average and entry count
• A day-by-day chart stacked by project
• A breakdown of every project's share of your time

ORGANISE YOUR WORK
• Projects with their own colours
• Clients to group projects, and tags for the kind of work
• Make a project billable by default
• Archive finished projects to keep your lists short

YOUR DATA STAYS YOURS
