DayLog

"Where did my day go?" If you've ever wondered that, DayLog is for you—a simple time-logging app that records how you spend your day with a single tap. Sleep, work, meals, exercise, hobbies—just tap what you're doing now. The previous entry ends automatically and the next begins. No tedious input, no separate start/stop buttons. As your records build up, your day, week, and month come vividly into view. Timeline, donut chart, activity calendar—see your time in numbers and in color. And the more you use it, the more DayLog learns your habits. "Saturday morning—your usual grocery run?" It predicts what's next, so logging gets easier every day. And on the 1st of every month, your "16 Types" result arrives—morning or night, deep focus or quick switching. No questionnaire: your type is diagnosed from how you actually spent your time, delivered as a shareable card with its own character. Every Monday, a weekly report looks back on your week with numbers and gentle insights. ■ Made for you if you ・Lose track of where your day went ・Want to rethink your time and live a little better ・Couldn't stick with complex expense or journaling apps ・Want a light grasp on your sleep and exercise habits ■ Key features ・One-tap logging (switching is automatic) ・Timeline / donut chart / activity calendar ・Widget & Live Activity keep tracking effortless ・Stop reminders / 12 built-in categories ・Customizable categories: add your own—Childcare, Pets, Gaming, and more (up to 18).
