About TimeHack: Time & Study Log
Make your own time work for you. The day fills up and disappears. You studied hard, but you cannot really feel how far you got. TimeHack is a deliberately simple time log that turns those hours into something you can see. WHAT IT DOES Simple to record. No setup, no accounts. Add an entry and mark it done. Analysis that fits the question. Today, this week, this month, this year - your time is totalled up for you automatically. Progress you can see. Study, reading, training: watch the hours add up as a chart. "I actually did this much" is what carries you into tomorrow. Find the time you were losing. Once the aimless hours are visible, your days settle into a rhythm on their own. GOOD FOR - Logging study for an exam or a qualification - Tracking billable or side-project hours accurately - Anyone looking for a simple tool to build a habit - Ending the day with something to show for it BUILT TO STAY OUT OF THE WAY Recording should never feel like work, so everything unnecessary has been stripped out. Every time you open the chart, your effort is right there. Your entries stay on your device. Nothing is sent anywhere. Export to CSV any time from Settings.
