Please refer to diary apps such as Day One.

・Since I use it for diary purposes, I would be happy if a notebook function specialized for diaries was added in the future. If a function like a map database is added, it would be great if there is a mechanism that can record location information.

・If there is a calendar function that can be checked back on a date basis, I think it will be very attractive as a diary.

・There are a ridiculous number of notebooks in the diary, and there are a lot of photos and videos, so it would be very helpful to have a function that allows you to easily manually clear the cache.
