The search giant Google has started an app for people to give just $1 to different charities. Its 'One Today' app shows a variety of charities every day. Its website says: "Open the app, and you're presented with several projects to which you can donate $1 with one click….And most people can afford the occasional $1 donation." It is only in the USA on Android mobile phones. Google hopes to start the service around the world. A Google spokeswoman blogged: "We look forward to continuing to improve…and to growing our dynamic community with incredible [non-profit organisations]."

The One Today website said Google has always supported non-profits. It said: "One Today makes fundraising easy for non-profits; it also makes giving simple and fun for users." The app will mean people can learn more about non-profits, and share their favourite projects on social media sites so more people donate. It asked people to "do good daily" and help hundreds of non-profit projects be successful. Google said: "We're amazed by the great work non-profits do [every day] to make the world a better place, and we're [happy to make] a new platform which helps [them]."
