I have used this app before..
Pros:
- There are a lot of fun stickers and filters
- It's easy to save your photos and videos
- Instant sharing
- Easy to use + simple UI
Cons:
- In some devices, the app can be unresponsive
- When filter or sticker is applied, the screen slows down
- Sometimes, a face can't even be recognized
- App slows down when a lot of stickers are downloaded
