Revoda was a mobile app created for the 2011 Nigerian elections to allow citizens to monitor the electoral process and report incidents of fraud, violence, or other issues from their polling units via their phones. The app collected reports on elements like election officials, voting materials, and reported results. It aimed to turn citizens into informal election observers and verify results. Over 10,000 people downloaded the app across Nigeria, allowing for increased monitoring of the elections through citizen reporting on the app and social media. However, a challenge was lack of publicity, limiting the ability to spread awareness of the app more widely.
