A mobile app developed in Scotland has the potential to help millions of farmers in East Africa.

The VetAfrica app will allow vets, farmers and others working with animal health in Kenya, Ethiopia, Uganda and Tanzania to diagnose diseases quickly and identify the most effective drugs.

The app was developed by Glasgow-based technology company Cojengo, in partnership with software giant Microsoft and its 4Afrika initiative.

Deputy First Minister Nicola Sturgeon said the technology would tap into a "mobile revolution" on the continent, as she met with representatives of both companies in Glasgow.

Ms Sturgeon said: "Scotland has a global reputation as an innovative nation and Cojengo has expanded its horizons internationally to help transform the lives of rural farmers on the African continent.

"Working with Microsoft, the company has embraced and tapped into the mobile revolution sweeping Africa.

"Cojengo is a shining example of a new generation of creative Scottish companies with the ambition and skills to create and grow successful businesses."

The company was supported by Business Gateway Glasgow, Scottish Enterprise, University of Strathclyde's Entrepreneurial Network and the Gabriel Investment Syndicate to develop the technology.
