 Awell Score is an API developed by the [Awell Health](http://awell.health/) team used to calculate validated scores for clinical & patient reported outcome measures or perform any other clinical algorithms. **The API currently has a library of over 100 validated scores.**
 
-It was originally developed as an in-house microservice used by our own products. However, in September 2022 we decided to make the project open source and make it available to everyone.

-### Roadmap

-We would love to hear ideas from you on how to improve the API and add functionality. Currently no major features, besides adding new calculations & maintaining the current ones, are planned.
