Read full description

Simple free calendar app. Can display the statistics of registered events, and can also use it as a life log with simple input. The concept is to be able to input events easily. You can see at a glance "How many times did you do this year?", "How many times did you do last month?" Events that are registered many times can be easily registered with quick input. The display of statistics can be freely customized, such as numerical lists, graphs, ranking, etc. Features: - Label your calendar to manage your events. - Select a label and enter an event easily. - Once you have entered an event, long press it for quick entry. - View statistics by label. - The contents of the statistical display can be customized. - Linking with device calendar. - Show Rokuyou <FAQ> - Why is it free? I personally released this app for non-commercial purposes from the beginning in order to improve my skills for my main job. We have also implemented ads, but there is no point unless they are placed in a prominent place, and this makes the app less user-friendly, so we have temporarily stopped displaying them. - Why did develop this? The OS standard calendar is also installed, but - Easily enter events - Look back at the statistics later - Show Rokuyo (even paper calendars are rare these days) started development based on these concepts. - Where is the data stored? Data is only stored on your device. We have not built a dedicated server because of the running costs. The device calendar was initially built in to read holidays, but now it can also be written based on requests. - What are your plans for the future? I continue to use this app myself, so I would like to continue updating it regularly. Please use it if you like it.
