Keeping our SDK small and out of the way is a key priority for us at Felt. We carefully select our dependencies to only add functionality that we want and use compiler rules to remove any un-used code and bloat.

Embedded Care SDK

Our Embedded Care SDK adds 6 MB to your final App bundle. This includes all the statically-compiled functions to serve care.

Experience Bundle

At run-time, the SDK pulls the Experience Bundle from our servers. This bundle can vary by client, but typically ranges from 0.6 to 1MB. This is stored in the app cache on the user’s phone.
