The app does it's intended purpose. It's not bad it's just I would like the option to make one word bold or italicized not the whole paragraph I've written. Same thing with the colors, what if I want part of a paragraph to be purple and the other part green? I can't. And the options for free stickers are extremely limited. Overall it's okay, I've never done journaling on an app before so it's convenient for me. I have a 2 year old, it's hard to just sit down and write so using an app is easier

I really enjoyed the app, but when I tried to log in on other devices and restore my backed up entries, I was unable to do so. It's sad because now I'm unable to get those entries on another device, even though I backed them up to my account

I've been using this app for pretty long, I've never had any issues but a few days back I had to log in my account on another device and 5 of my entries just vanished. I can't restore them. They were very important to me. Now that I opened it on my old device again, the entries are gone from this one too. I hope I can restore my entries somehow.
