"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). Rename, re-icon, reorder ・Insight cards: discover patterns you'd never notice ・Predictions: gentle suggestions based on your habits ・The 16 Types: a monthly, shareable type card ・Weekly report: every Monday, a look back at your week ■ Privacy first The contents of your records—what you did and when—stay entirely on your device and are never transmitted. No account required. iCloud backup is supported, so switching phones is worry-free. To improve the app, we collect only anonymous usage statistics (which features are used). You can turn this off anytime in Settings. ■ DayLog Pro (monthly subscription) Free is plenty for everyday use. When you want to look back deeper, go Pro. ・Set as many goals as you like (free plan allows 3) ・View all past data (beyond one month) ・Detailed analysis (day × time-of-day heatmap, long-term trends) ・All insight cards ・Monthly / all-time reports, custom-period analysis ・Color themes Your first tap starts today. And your day begins to come into view. --- - Terms (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ - Privacy Policy: https://sites.google.com/view/daylog-app ---

Verdict
The clearest difference is in-app purchases: Linky at none against DayLog's 1. DayLog's advantage is update cadence (every 3 days vs weekly) and iOS requirement (16.4 vs 18.0). On price, ads and device support there is nothing between them.
