For several months now, some 200 Kenyan refugees in the Dadaab camps have been helping foreign companies with a range of repetitive online tasks. But sometimes the quality of the work can suffer in part because of translation. “They speak English, but might not know slang,” says Lukas Biewald, who is CEO of CrowdFlower, a San Francisco-based crowdsourcing startup that recruits thousands of people to complete repetitive tasks for big companies and is overseeing the work. CrowdFlower is hoping a new iPhone app will address that issue.

With the new app, iPhone users in the U.S. will be asked to complete the same tasks as the Kenyan refugees to help improve the accuracy of the Kenyans’ work. If all goes according to plan, Biewald says the Kenyans should be able to double or even triple their wages. “If we can get the same level of quality with half of the work we can pay them twice as much,” he says. Samasource, the non-profit agency Crowdflower has been using to find Kenyan refugees to fill the jobs, says the refugees will now be able to earn at least 50 cents an hour—a substantial amount in the camps—while learning computer skills.
