Ex-Apple designer Sebastiaan de With and ex-Twitter engineer Ben Sandofsky have combined forces to bring an iOS camera app that adds a ton of features to the camera that already sits within the iPhone.
Named Halide, the app is targeted at advanced users who want to have more control over settings that aren't available in the native app. It has a gesture-based interface that is designed to feel like dials of a camera.
Extra features include focus peaking, adaptive level grid, and RAW support. It's definitely worth looking at if you want more control over the photos you take with your phone. Head here to find our more about the app.
