Akestam Holst has come up with an innovative app for Swedish charity SOS Children's Villages that links donations to smartphone usage. With AppAid, currently available for Android if you have a Swedish mobile subscription only, every time you use your mobile you collect money for potential donations.
The app essentially gives you stats about your smartphone usage (such as how often you unlock your phone, interval and frequency) - but it comes at a price. Every time you unlock your phone, 0,2 SEK (about 3 cents) is 'collected' in the app for SOS Children's Villages. You also get reminders about how much you've 'collected' and you can then choose to donate the money directly.
