Cycling app of the week: Better Bike Light

This Android-only app turns your phone in to either an emergency front or rear light, useful if you're caught out with flat batteries

What is it?

Ever forgotten to charge your light and it’s gone flat on your way home? This app gives you a useful solution in this situation, allowing you to turn your phone into either a front or back light. You need a flashlight on your phone for the front light settings to work, and it requires access to your camera to control it. The back light actually just takes over your main phone screen, turning it into flashing red arrows that are surprisingly bright and visible. This is also adaptive, so when you're slowing down it will hold steady like a brake light. You can also use a bluetooth headset to indicate turns so you needn't take your hands off the handlebars.

How can it help me?

Obviously, this app could get you out of a pickle if one of your lights has gone flat on the way home. In the photo above we see the phone mounted to a flat rear light inside a clear case, which brings us to its main shortfall... you'd think cyclists who are prone to memory lapses by not charging their lights might not always carry the necessary equipment to do this! I found it is visible enough to be seen through a clear rain jacket in a back pocket though, and with the brake light and bluetooth turn indicators, perhaps it's good enough to be a viable replacement for a back light in some cases. The front light option is more readily useable providing you have a phone mount fitted to your bike. 

What makes it unique?

While there are other apps that turn your phone into a torch, this is the first we've seen that also has a back light option. It's impressively visible but as previously mentioned, you'll have to be organised enough in the first place to find somewhere to mount or carry it. There are multiple front light modes, making this a pretty comprehensive replacement for a flat light when needs must. 

Where can I get it?

The app is completely free and is only available on Android. Download it here. 


After cobbling together a few hundred quid during his student days off the back of a hard winter selling hats (long story), Jack bought his first road bike at the age of 20 and has been hooked ever since. He was Staff Writer at 220 Triathlon magazine for two years before joining in 2017, and reports on all things tech as well as editing the live blog. He is also the news editor of our electric-powered sister site eBikeTips. Jack's preferred events are time trials, sportives, triathlons and pogo sticking (the latter being another long story), and on Sunday afternoons he can often be found on an M5 service station indulging in his favourite post-race meal of 20 chicken nuggets, a sausage roll, caramel shortbread and a large strawberry milkshake.
