Calendarlog is a time management and recording app. Compared to other management apps, Calendarlog stands out for its extreme simplicity and power. And the reason behind all of this is that it is built entirely on top of the system's calendar. Leveraging the inherent strength of the system calendar, Calendarlog primarily focuses on two things: visualizing the calendar and supporting calendar entries through timing. If you're already using a calendar, then Calendarlog is definitely what you need. 1. Visualize Calendar Data: The Calendarlog app presents the data from the system calendar in intuitive line graphs, bar charts, and pie charts, allowing you to easily understand your time allocation. 2. Multi-dimensional Analysis: Based on your preferences, you can analyze data on a daily, weekly, or monthly basis, gaining deeper insights into patterns and trends in your time utilization. 3. Timing Mode: The Calendarlog app supports a timing feature, enabling you to track the time spent on specific tasks or activities by setting timers. The recorded data can be directly written into the system calendar for easy reference and management. 4. Privacy Protection: Since the data is completely stored in the system's calendar and only accessed during visualization, Calendarlog itself does not store any data. Your privacy is 100% guaranteed.

Verdict
The clearest difference is rating: 问真八字 at 3.8 against EVlog's 1.0. 问真八字 also leads on ratings volume (57 vs 1). EVlog's advantage is update cadence (weekly vs monthly). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
