This blog post highlights Resolve to Save Lives, a non-profit initiative that aims to save 100 million lives from cardiovascular disease and prevent epidemics by applying scalable health processes. The organization partnered with two development firms to build a mobile app called Simple, which is an electronic health record containing basic patient contact info, BP history, and current medications. Simple solves the problems of paper records being too slow for healthcare workers and easily lost by patients. The app was built offline first due to unstable network and power reliability in India, and its asynchronous data syncing mechanism allows it to run smoothly even without internet connectivity. Sentry is integrated with Simple to provide error tracking and monitoring, which helps the team identify and fix issues quickly. Simple is a free and open-source app that aims to make people healthy, and its open-source code ensures it remains a complement to existing electronic medical records rather than a competitor.
