TIME TRACKING WITHOUT A SIGN-UP – OPEN, START, DONE. No email, no password, no account. ProjectTimeTracker records your working hours per project, works completely offline, and turns your houres into a clean timesheet. Built for freelancers, contractors and anyone with flexible hours who has to prove or bill their time – without team software and without a learning curve. HOW IT WORKS: • Create a project, hit start – the timer keeps running even if you close the app or restart your device • Live Activity on the Lock Screen and in the Dynamic Island: project, elapsed time, status at a glance • Forgot to start it? Add the hours manually afterwards • Notes and tags per entry, so every hour has a reason TIME GUARD AGAINST OVERWORK: Set a daily limit, for one project or across all of them. A progress ring shows where you stand, and when you hit the limit the app reminds you to call it a day. Other apps optimise for more billable hours. This one doesn't.
