Find the exact colour of any pixel with this handy app
Once you give it access to capture everything on the screen, Pixolor displays a floating circle that shows colour information – RGB code and nearest Material Design shade. So by dragging it around and pinching the screen to zoom, you can discover the precise colour of anything. It also shows the distance moved and lets you measure areas. Tapping a colour code copies it to the clipboard or alternatively, use Pixolor’s notification in order to share it or possibly open the app for a colour wheel and palette.

Don’t want to pay out for a smart TV? These three gadgets will give you all the features without breaking the bankAmazon Fire TV Stick
The Amazon Fire TV Stick is a tiny, Chromecast-style dongle that plugs into the back of your TV. Unlike Chromecast it runs Android, so it’s possible to install Kodi directly onto it.Android TV box

This lightspeed wireless communications technology could power the Internet of Things – but how does it work?
Regular Wi-Fi uses radio waves to connect your devices to the internet. However, in much the same way as an old-fashioned analogue radio will crackle with static or lose its connection due to atmospheric interference, Wi-Fi can sometimes drop out. Bluetooth devices, baby monitors, microwave ovens and everyone else’s Wi-Fi can all interfere with yours.
Li-Fi is different. Rather than using radio frequencies, it uses visible light to transmit data. It’s not a new or novel idea: in 1880 Alexander Graham Bell designed what he called a photophone (later known as a radiophone) that could transmit audio using light. He considered it his greatest invention – “greater than the telephone,” he said – and the technology itself was the starting point for the fibre-optic networks we’re familiar with today, which send pulses of light down optical fibres to transmit data.
This free app serves up experimental live-data wallpaper for your phone
Meter is an experimental app from Google Creative Lab that offers a data-driven live wallpaper that reacts to up to three aspects of your device: wireless signal strength, battery and notifications. Each time you unlock your phone it cycles to the next visualisation type, but it’s a shame you can’t actually switch between them manually. The visualisations are very simplistic in design yet they can be manipulated by tilting the device.
Store your instant messaging chats on Google Drive to keep your data safe
WhatsApp Messenger is the most downloaded messaging app on the Google Play store with over one billion downloads, so it’s a little surprising that it’s taken until now for the app to offer a backup service for its users’ messages. If your phone recognises you already have WhatsApp Messenger, it will ask you if you want to download the new version. Tap Install to get the update. It won’t ask for any new permissions unless you’ve altered the settings to deny the app access to certain areas.
