★★★★★ news live · Oct 11, 2026
It's a good dairy, and it keeps our secret safe and no one will know our secrets it has a lock if an intruder try to read your dairy the photo will get caught of it
★★★★★ ria lou crespo · Jul 16, 2026
Loved this app sm!! I downloaded it back in December and I use it to write stories. I recently got a new phone, and I'm reinstalling this app, I just hope I have an acc or SMTH, LOL! Five stars, definitely! Edit: my ex best friend deleted the app on my phone :\ so how can I get my stuff back? Still love the app btw, im publishing a story sooon
★★★★★ María René Valencia · Aug 4, 2026
I stopped writing in my diary because I was too lazy to take my diary out and write with a pen all those words until my hand hurt and I gave up, this helped so much. I finally check in daily like ive been wanting, love the app.
★★★★★ Rlene Rosen · Aug 10, 2026
It's nice writing in a journal with a lot of options and very inexpensive in return.
★★★★☆ Valerie Olivarez · Jul 25, 2026
It was really good! I actually had a review previous to this one, but I recently wanted to see if I could go back in to write something, but sadly I forgot my password and this new update doesn't have much back up if you forget the password, so I'm low key not able to use it until I remember it. However, the app is genuinely amazing and one of my favorite apps to write in, so I'll do my best to figure it out 😭
★★☆☆☆ Holly S · Oct 17, 2026
I like this diary because I can add pictures to it and things like that. But also I can buy a one-time fee membership instead of a monthly fee. Edit. I used to like this app. But despite me paying for a lifetime membership I have to watch ads now. I will have to find a way to download all my entries and leave. This is actually not cool at all. Especially considering I paid for a lifetime membership
★☆☆☆☆ Jonathan Davidson · Aug 26, 2026
Play store claims this app doesn't collect data but it's an online only app similar to a progressive web app which shares your data you provide to 210 vendors. How is this private when the first thing shown is a cookie prompt for data collection? Nah. I should report this.
★☆☆☆☆ Jamie Porter · Jul 26, 2026
Ads? Ugh. Ads with audio?! Big no, no! More than one ad in a row?!?! Come on. Stop with the ads. I'm not paying for premium, I'm just going to delete this app and find another
