There are very few companies that “get” mobile health data and can deliver an end-to-end solution like Overlap. We had been struggling to find a technical partner to help us power a sub-study for the Nurses’ Health Study 3, for a protocol involving a smartphone app and Fitbit wearable device. We needed a partner to actively collaborate with us and customize the app to our specific protocol. Overlap saved us. We’re enrolling 500 nurses using Overlap and we couldn’t be happier. Oh, and the data generated by Overlap is helping us perform research on complex high-dimensional data. Without Overlap we would have wasted time and money trying to make sense of these novel data streams.
