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!

Terrible update doesn’t let you change the time anymore.

I use this app to put my medicine in. When I forget to put in I could always go back and put my finger on the line of the medicine i took time after I’ve selected the medicine that I have already put in I could put my finger on the time and it would let me change the time to the correct time. Now I do that it’s blank I cannot change the time so I cannot keep an accurate account the medicines I have taken this was a great app five stars I would’ve even given it a 10 now it’s no longer an app that I can use for my medication. It was the best one I have ever found. This just happened after the new update. I have an 8 plus phone. I have had this app for years. I could bring it up at the Doctors office and show them all the medicine I had taken, even print it out. I now will have to find a new one Sooo disappointed. I hope this is an error in your update and it will be corrected. I should never have updated this. I find most updates only make the apples worst. You don’t seem to follow through to check that everything is done correctly and made better before you update. Sooooooo upset and disappointed.
