Bringin' Up Baby
Bringin' Up Baby is an iOS app that allows people to register their beloved children's memories.
Among its features are creating memories, uploading pictures, importing posts from Facebook as memories, and sending memories to Kite so they can be printed (as pictures, mugs, photo albums, and many more options).
The app was built in Swift using the VIPER architecture, uses a Firebase back-end, and integrates with Facebook, Twitter, and Kite.
