Mirai Nikki is a lifestyle app developed by Leugim Starwind for Android devices. The app offers a unique feature of producing noise simulation, which lets you write an actual diary for yourself. Though the app cannot predict your future, it allows you to write about your past. The app is compatible with Motorola Moto G, Sony Xperia M, and Tablet Huaweii Media Pad 10.

The app's primary feature is to write a diary, and it allows you to add or delete pages by long-pressing them. It also has a save button to save the page easily. You can change the title of the page with a button and get a time stamp with another button to save time. Moreover, the app has a back button to go back to the previous page. You can use emojis in the app, but only those that come with your phone.

Overall, Mirai Nikki is an excellent app for those who love to write diaries. The noise simulation is a unique feature that makes the app stand out. The app is easy to use, and the interface is user-friendly. However, the app lacks some advanced features, like password protection and cloud synchronization.
