About this app

Turn your phone into a soft, adjustable book light for reading at night.

Booklight is a simple screen light, reading lamp and night light that helps you illuminate a paperback, magazine or nearby space without switching on a bright room light. Choose your favourite colour, adjust the brightness and enjoy a gentle light that stays on while you read.

Join thousands of readers who have chosen Booklight for comfortable reading after dark. Perfect for reading in bed, travelling, relaxing, working at a desk or creating colourful photography.

A book light that is always with you


No bedside lamp? No problem. Use your phone screen as a portable reading light and angle it towards the pages of your book. The soft, even display light is a practical alternative to a harsh camera flash and helps you read without lighting the whole room or disturbing someone nearby.

Choose the right light for every story


Create the atmosphere that feels right for your book and surroundings. Explore a wide selection of warm, cool and colourful themes, including amber, gold, orange, red, pink, purple, blue, cyan, teal, green, lime, grey and white.

Fine-tune the screen brightness and colour intensity for anything from a subtle dim light to a richer, more vivid glow. Booklight remembers your choices, so your preferred reading light is ready the next time you open the app.

Calm light with a little movement


Make your night light feel more atmospheric with a soft centre glow or gentle animated effects. Choose flowing Waves or drifting Mist to add subtle movement while you read, relax or set the mood.

Bookmark your current page


Save the page number where you stopped reading and quickly find your place when you return to your book. Your bookmark is always close on the Home screen.

Save quotes, notes and ideas


Capture a memorable quote, a thought about the story or an idea that arrives while you read. Create notes directly from Home or Fullscreen, browse your saved thoughts and edit them whenever you like.

Sleep timer for bedtime reading


Reading before sleep? Set the timer using hours, minutes and seconds. Booklight closes automatically when the timer ends, making it a convenient bedside light or gentle night lamp.

Make Booklight yours


Personalise the Home screen with the controls you use most. Keep quick access to brightness, Fullscreen, Torch, Bookmark and Notes, and adjust the transparent glass interface to complement your selected colour.

Useful wherever you need soft light


• Read books in bed without turning on the main light
• Use a gentle screen light on a bus, train, metro or plane
• Create a small desk light for late-night tasks

This is an app I can get behind! I already use my phone's screen to check my door locks before going to bed, or to find my way around the bedroom without waking my wife. Or to put my CPAP on without having to turn a light on (it is very fiddly - just like the add on TV). I never thought to use it as a book light though. And the fact that a timer is included makes this the perfect app for me. (And there is even a spot where you can leave the page number you were on.) Thanks developers!

I used to really like this app. It's got a place to put your page number, it has adjustable colors and brightness, and ads used to be different. Now it pops up a bulb in the middle of your screen periodically and makes you watch an ad to get rid of it. The problem is the screen faces your book, not your eyes, so you don't see it. I now have that light bulb symbol burned into my screen regardless of what my phone is doing at the time.

I've been using this app for about a year now and I absolutely love it, I love the fact there is different colours to choose from, but I would also like it if there were more colours/themes that are not as bright. I also really like how you can keep track of what page you are on in your book. I have never had a problem with this app I think it is perfect for late night readers and I highly recommend to anyone that likes reading in dark rooms.
