Web reviewer Kate Russell tries out a free app called Local Mind that puts a question and answer layer on top of popular location check-in apps, so you can ask someone who is at your favourite restaurant what the atmosphere is like.

She also tries out Jolicloud.com, which is a portable online desktop.

If social interaction is important to you she has a suggestion for an effective backup service at socialsafe.net .

If you want to improve your English, English-Attack.com is a new site designed to encourage learning by using games and video clips.

Finally there is an Android app for sharing photos across the major social networks. Lightbox Photos is free to download and there is an offline mode, so you can browse through your contacts' uploaded snaps at a time that suits you.
