At your seat in the cinema. In your car's footwell. Under the bed. These are all places where you will inevitably drop stuff, and retrieving them can be tricky, especially if it's dark and you haven't got a flashlight. Let's be honest now, how many people have you come across who has had a flashlight at the ready?

In today's world, you would be mad to carry a torch or a flashlight around if you're not a tradesperson. Why should we? Our phones can double as a decent flashlight in an instant.

Newer iPhones (4 and 4S) have a built-in LED flash that's usually activated by the camera. However, you can control the LED without invoking the camera, usually with a flashlight app. Finding the right application is a different matter. Go ahead and try if you don't believe me -- search for "flashlight" in the iTunes Store. Frankly, most of the results are crap, and you wouldn't know where to start. So I did the heavy lifting for you and decided that the best flashlight app for iOS is indeed Flashlight.

I picked Flashlight because it's free. It's not ad-supported. And best of all, it's smart -- it remembers your last setting and can turn the LED flash on just by launching the app. So in a nutshell, just one tap is all it takes!

The application's interface is simple and utilitarian (probably because it isn't bogged down by ads!). At the very top, three options are presented to you: OFF, Strobe and ON. If ON is selected, the LED flashes constantly, and the only other option available is to darken the screen.

If you choose to darken the screen, this is all you will see. As boring as this might sound, in a real-life scenario, a dark screen allows your eyes to adapt to the flashlight's illumination.

The Strobe mode causes the LED to flash intermittently according to the interval set by the slider. While in Strobe mode, you may also choose to sync the flashes equally (on and off for the same periods of time) or asynchronously by adjusting the slider individually.

When in OFF mode, a new function appears and provides you with the ability to manually control the LED to communicate in Morse code. The LED will remain lit as long as your finger is on the button.

There are quite a lot of features in this tiny, free app; I must admit. But there's one more, that could just save your life -- SOS mode. When enabled, the LED will flash SOS in Morse code autonomously, so you can place your iPhone somewhere visible while attending to your emergency.

Flashlight is smart, as I mentioned before, because it remembers your last setting. So by leaving it in ON mode, your iPhone's LED will be enabled as soon as you launch the app. No more fumbling about in the darkness indeed. Flashlight is the only flashlight application I'd recommend, and is a true lifesaver. Download it for free from the iTunes Store by clicking this link (don't bother searching in the iTunes Store, you won't get anywhere).

Am I right? Is Flashlight really the best flashlight app for iOS? Or have you used better? Let me know in the comments.
