Cardiio

Cardiio develops intelligent algorithms for the monitoring of wellness, fitness, and chronic diseases using sensors. The job it does: designing and building iOS and Android apps.

Who is it for? Mostly businesses launching or rebuilding an app. Alongside the main category they mention Health Care and mHealth. As a very small company team themselves (1 to 10 people), they tend to serve customers of a similar scale best. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Cardiio is based in Cambridge, Massachusetts and founded in 2012. Their site is cardiio.com.

Things worth asking about: portfolio quality, app store experience, and maintenance terms. Ask for a trial on your own data, not a canned demo.
