Great app.

I’ve been using the app for a few weeks and it seems to work really well. The only thing I would like to see would be a way to do a search. This would allow me to search for key words through all of my entries.

Update: I received a message from the developer and they informed me that if I slide down from the start page you’ll see a place where you can type your search question.

Thanks for the great support.

Best journal/diary/notebook

I love this app. It’s exactly what I had been searching for for years. I ditched the rest any made this my primary journal. I like how I can do multiple books. I have one for vacation adventures, two for each child to keep memories for them and one just for person thoughts. I do wish there was a his option so when I show someone the app/book I can hide my personal notebook.

I’m very happy with this app!

This is a lovely app! The design is gorgeous, and it’s easy to use. The option to turn pages like a real book is a nice touch. I’d love to be able to delete books without having to manually delete each entry, but other than that, this app is perfect for journaling or note-taking!
