Nisce

Nisce is a photo and video gallery app that lets you organize your media in a fun, intuitive way. With Nisce, you can assign any emoji to your photos or videos, view them in personalized "collections" based on those emojis and synchronize those collections with your gallery.
Whether you want to group memories by mood, event, or theme, Nisce makes it simple to organize your content with just a tap.
Designed with simplicity and privacy in mind, your photos stay on your device and never get uploaded, shared, or sent anywhere.
