Why we picked this?

Apollo works like magic. It takes the depth data from Portrait mode photos and reconstructs a 3D map, allowing you to add realistic new light sources and cast shadows in real-time. You’re able to adjust the color, intensity, and distance of each light with only a single finger. Since the scenes are computationally rendered, light sources can even be put within the frame. Apollo only works with iPhones that support Portrait mode.

You love to play around with lighting in photos. Apollo’s results are stunning.

You don’t have an iPhone 7 Plus, 8 Plus, X, Xr, Xs or Xs Max.

Hindsight allows you to track the occurrences of anything and everything you wish. Each entry simply needs a title and a record of its first occurrence. Hindsight will then start a timer and keep it running while you’re away. Whenever an event takes place, swipe to record it. Alerts can be set up as well based on the time elapsed between occurrences. Each event includes detailed history and a histogram that can reveal patterns.

You’re interested in learning how often something happens. A lock screen widget and Apple Watch support make it even easier to keep track of occurrences.

You have an iPad. The app is designed for iPhone.
