Exceptional! Easy to use!

I have always kept a manual notebook diary. Recently, I considered transferring my journal to app-based. Before purchasing, I decided to try out available apps. This was my first choice. All went well for the first two days. (deleted the rest of my previous review).
With some reservations, I finally bought the app. After several journal entries, I felt a growing sense of doom. How do I get my journals into a different medium, like pdf, intact? How do I preserve my recorded thoughts from vanishing some day? What happens if I were to switch phone carriers? Can I sync my entries to a cloudbased repository to be retrieved at will? The questions are endless, and I hope Koji Ito, the developer will read these reviews, and take our interests and concerns into account. I hope he can read and understand English. Domo Arigato.
After using the app for some time, I felt a bit more comfortable with it, hence my reevaluation to 4 stars. The minimalist approach is impressive, but an upgrade that includes a search function would help navigate and locate critical records quickly.

One small suggestion

I gave this app 4 stars as opposed to 5 because there’s one small improvement that could be made to this app to make it perfect! This app functions as a personal journal for me to write my thoughts down in an to vent when necessary. The only thing is missing is that I cannot paste images or pictures onto the pages of the notebook. I can use emojis but I can’t paste any of my own personal images, Memes, or use my Bitmoji at all. I attempted to see if I could use my Bitmoji and it actually locks the keyboard down and then I cannot get it back to the regular keyboard in order to type in my passcode to allow myself back into my Notebook. There seems to be a bug there. I’ll have to wait several days for it to reset itself and let me back in. But I enjoy this app very much and I use it several days a week. I hope the developer will read this and consider my suggestion because it would be fantastic if I could paste in anything I wanted to on my pages. Thanks!

A journal, not a diary, with flexibility to write what you want

This is a plain, generally straightforward journal, that allows a person to write about what happens , their feelings, or whatever they want. This app fits the bill.

You can go back to a table of dates and add to something that you wrote, but unfortunately the addition is not dated. IAlso, if you find yourself at the index, getting elsewhere does not seem intuitive. You can see from there how to start writing, but not necessarily figure out how to find what you already wrote or the instructions. Once you figure that out (press the number next to the year) navigation is easier.

However I like the ability to write freely without limitations on the number of characters you use. I like being able to reread what I have written before and add to it even if I have to add the date of the new comments myself. I like this app a lot, and would give it a 4.5 if I could
