The default Camera app that ships with your iPhone (or iPad, or iPod Touch) has gained in creative features over its lifetime, but it’s still only functional at best, even on recent models like the iPhone 6S and iPhone 6S Plus.
The stock app’s overriding benefits are simplicity, reliability and ease of access – it’s one of the few camera apps you can quickly open from your lock screen, for example. And true, it does now also offer panorama, video, time-lapse and slow-mo shooting modes as well as HDR, manual exposure and eight stills filters.
