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

This app is kinda good but for sticker and all the cute things, we have to just buy the premium for almost everything and there should be more sticker, background and styles free and I expect that this problem should be changed . you can use it, when you use it sometimes and has password which is good. overall, it is best for sometimes but gets a little boring when you use it everyday. Also, there are little ads but long so don't increase ads and pls fix this problem . Thanks 👍
