DeepSi

DeepSi is a simple utility app for current generation iPhone that have built in Lidar and TrueDepth cameras that allows you to capture moments where light is not present.
I turns the depth data from these extra sensors on certain iPhones and iPads into fun photos and videos that demonstrate the shape of various subject matter in front of your device.

It can capture photos by single tapping the shutter button.
It can capture videos by press and holding the shutter button.
It can change the colors of the video by swiping left or right.
The colors are also dynamic against your system setting of Light or Dark Mode
It can switch between a front facing True Depth camera and a rear facing True Depth camera.
It saves all the media to a DeepSi album in your phones photos library.

This app uses no third party libraries and does not even make a single network call, it can be used completely offline.

It can be used as a rudimentary "night vision" viewfinder.

DeepSi also works with Shortcuts and Siri:

- Make Video from Frames turns a set of images into an mp4 (choose 1-120 fps, optionally add an audio track) using DeepSi's own video pipeline.
- Get Latest Captures hands your most recent DeepSi photos and videos to other Shortcuts actions as files.
- Read or change the depth Color Theme from Shortcuts - all 12 themes, and a live capture session recolors immediately.
- "Get my latest DeepSi capture" is available from Spotlight and Siri with no setup.

Your selected color theme now also sticks across launches.

The app is pay once, no subscription and there will never be a subscription.
