Ratings and reviews

This diary is very cute and pretty! I love the cozy feel when I write and the cute Mongles and I like that there's so many themes and stickers to use. Although, I have to watch ads to unlock them. But it makes it feel like a Gacha game so it's okay. I like the app so I think it deserves 5 stars. Pls let us also be able to give color to the fonts we pick and then using stuff like links, bold, italic, bullets, etc. looking forward to any further updates!

HIDDEN GEM!! 💎📒 I never thought journaling would be this fun, even addictive. I'm having a backup issue; the feature doesn't tell me whether a backup has been made. I wish there was a clue / mark so I could know it's backed up properly and not worry about losing my journal data. I luv it! ♡♡

Made my day ☺️ but I think that it should have a feature of having a password setting so it will give that personal diary feel. So that's my only request please have a password setting when opening this app so no one will be able to see what I wrote. It is absolutely good.
