We present txteagle, a system that enables people to earn small amounts of money by completing simple tasks on their mobile phone for corporations who pay them in either airtime or MPESA (mobile money). The system is currently being launched in Kenya and Rwanda in collaboration with the mobile phone service providers Safaricom and MTN Rwanda. Tasks include translation, transcription, and surveys. User studies in Nairobi involving high school students, taxi drivers, and local security guards have been completed and the service has recently launched in Kenya nationwide.
