Fund them on Indiegogo! Make a difference by donating to this project to provide medical apps on smartphones to seniors.
They have raised almost $28,000 and now there are now less than 7 days to reach their goal of $50,000. All the Silverline apps can be used anywhere in the world - and are optimized for the United States, United Kingdom, Australia, Hong Kong and Singapore. The apps are currently available in English and Chinese (Mandarin), and will soon be available in other languages too.
For $79, they will provide one underserved senior with an iPhone 3GS, with year long data and voice plan etc. They just added a new combo pack, where for $149 you get a refurbished iPhone with silverline apps. This would be in US dollars.
