Rapp

We've never had a reading like this on a swagometer!

Finally, an app designed in an underground lab by a team of country's best hip-hop scientists, that lets you record and rate your flows on the spot. Cutting edge AI, originally developed at NASA, analyzes your flow and assigns you a score depending on your rhyming, wording and rhythmical abilities.

The app's built in social networking allows you to compete with other users in climbing to the top of the leaderboard.

This is - the definition of a rap flow.
