Torch on Focus is a new free jailbreak tweak by iOS developer Guy Kaplan that improves your iPhone photography in low-light conditions, which make it more difficult to focus on your subject.

The tweak manages this by turning on the LED flash on the back of your iPhone from the moment you begin to focus on an object with your camera, so your focusing never skips a beat.

While the iPhone’s camera is great at focusing on subjects in well-lit environments, it often yields unwanted results in low-light conditions because it’s more difficult for the iPhone’s camera hardware and software to discern one object from another when there isn’t enough light.

After installation, the LED flash stays off until you manually tap on an object in your viewfinder to focus on it. Moreover, once it’s turned on, it stays on until you close the Camera app or turn the flash off manually, which makes it easy to take one shot after another without the flash ‘strobing’ on and off in between shots.

The obvious benefit to Torch on Focus is being able to see and focus on your subject before you even tap on the shutter button to snap a photo.

The additional light allows the camera hardware and software to discern the subject more easily, yielding improved focusing performance and precision before the shot is ever taken. This means you won’t be re-taking your photos as often when your photography environment isn’t ideally-lit.

Torch on Focus adds a simple preferences pane to the Settings app where you can toggle the tweak on or off on demand:

It’s worth mentioning that you need to leave your Camera app’s flash setting to the “On” or “Auto” position instead of the “Off” position. If you keep your flash “Off,” then Torch on Focus won’t be able to override your stock setting and the tweak won’t work properly.

Torch on Focus has a lot of potential to improve your low-light photography, so if you want to give it a try, you can download it for free from Cydia’s BigBoss repository. The tweak works with the stock camera app on jailbroken iOS 10 devices.

    Actually it’s supposed to turn off when your device finishes focusing, and not stay on until you close it.

    It should work on iOS 9.0.2 as well, don’t you think?

    • I dunno, I don’t have an iOS 9.0.2 device to test.

    • Digitalfeind

      It works on iOS 9.0.2. Tested on my 6S.

        Good to know! Installing and testing, right now.

        Tks. ✌

    It would be nice if it automatically turned itself off as soon as you hit the shutter button instead of having to manually do that.

    • Guy Kaplan

      Actually it does turn off automatically as soon as it finishes focusing, at least, its designed to, if it doesn’t, I’ll be happy if you could send me a video of that along with your device details (iOS version and device) so I could post a fix.

        This tweak doesn’t work on iPhone 7 plus iOS 10.1.1 when I hit the focus the flash comes and the screen just blurs out.

      • Diego Milano

        I haven’t tried it, maybe the reports are just referring to a possible bug then; if it’s designed to work that way, then great job!

    Iphone 7plus running iOS 10.1.1 tweak doesn’t work. Has a bug makes the screen blurry when trying to activate it in the camera. Flash comes on but unable to see the screen.
