This is a good app for recording memories. has lots of backgrounds, themes and stickers to choose from. I did pay for the subscription because I do like it and because there are ads on the free version. there are also stickers and backgrounds that you cannot access without the subscription. I gave it four stars instead of five only because it advertised that the backgrounds and stickers change weekly, however they do not. New backgrounds are added frequently but not stickers. It's a great app 😁

I absolutely love this diary app! 💕 It’s cute, aesthetic, and really easy to use. I love how many features and tools it has, and the calendar makes it so easy to keep track of my entries. It feels like a perfect little space to write about my day, thoughts, and memories. Definitely one of my favorite diary apps! ✨📖

It's good, but there's no passlock protection like it claims. Thankfully my phone has passlock protection. & I don't mind the ads. It's what keeps this app free. Not all features will be free obviously but that's ok. I enjoy the numerous free themes and fonts.
