Your time is precious. C-Time shows you where it really goes - automatically. How many hours did you actually work this month? How often did you make it to the gym? C-Time answers these questions without you lifting a finger: define your places once, and the app clocks you in when you arrive and out when you leave. No buttons to press, no timers to forget, no extra battery drain - it uses Apple's geofence technology, not GPS. Open the app and your numbers are just there: today, this week, this month, this year - clean statistics for every place, automatically backed up to iCloud. WHAT C-TIME DOES FOR YOU • clocks you in and out automatically at your places - work, gym, wherever • shows the running time live on the lock screen, in the Dynamic Island and on Apple Watch • history per day, month and year with clear charts • set a daily goal per place and see today's over/under at a glance - turns green when you reach it • a Home & Lock Screen widget with your goal ring - progress at a glance • add a note to any check-in - shown in history, in the CSV export and on the main screen • automatic daily break deduction per place - e.g. 30 min once a day passes 4 hours (off by default) • exports a beautiful PDF report - perfect for time sheets and invoices (also CSV / e-mail) • notifies you on arrival and departure, per place if you like • manual clock in/out and editing whenever you need it • automatic iCloud backup, plus backup to a file and restore • speaks English, German, Spanish, French, Italian, Japanese, Korean and Chinese Set it up in one minute. Forget it. Know your hours. TIPS □ The automatic mode runs at its best when Wi-Fi is enabled. □ C-Time uses the same technology (geofence) as Apple's "Reminders" app. ================================================ What customers have said about C-Time: ================================================ △ Incredible app. I always forget to clock my time. With this app, its automagically handled. Love it! △ Pretty neat. I like this app a lot. It is really helping me track my work time without me having to remember to enter anything. △ Many uses.
