We’ve all used our smartphone displays to help us navigate dark spaces, say our houses at night. But if you want something that works like an actual flashlight, this free app from Surpax (with a funky ‘¤’ symbol in the name) uses your iPhone’s camera flash — the simple white LED beside the lens — to produce a surprisingly bright beam you can turn on or off by sliding a screen-centered power button up or down. What’s more, you can rotate a dial along the top that’ll change the beam’s brightness or set it to strobe (you know, if you suddenly get the urge to Flashdance). The only catch: Free means ad-supported, though the ads only take up about one-tenth of the screen.
