In the modern world, a lot of things have changed and we have a lot of new things to deal with. For example, we have social networks, the Internet, and all these new things make us a lot more connected to each other than ever before. But, at the same time, we also have more things to hide and keep secret than ever before. And we need a safe place to keep all these secrets and where we can write down all our thoughts and plans without anybody else seeing them.

Niki: Cute Diary App is one of these secure places with a fingerprint lock. You can also use a lot of beautiful emojis and fonts in this journal.
