Smart M:Panel members voluntarily install our research software on their smartphones via a text link sent to their phone. The software records usage of various mobile phone features - email, web browsing, games, etc. - and securely returns the data to M:Metrics without interfering with the normal use of your phone. Panelists are rewarded for as long as they opt to keep the software installed on their phone.
you get paid 15 pound initially and then £5 for each month u keep the app on your mobile and you can opt out at any time....plus you get entered into a monthly draw.
i think it looks pretty legitimate and handy if your looking to make a few extra pound for installing an application you wont notice. ill leave it up to you to make your mind up.
