Surgent is a health and fitness app designed for serious runners. It focuses on showing objective evidence of training progress by analyzing heart rate at pace and efficiency gains over time.
Surgent tracks trends like your heart rate at specific paces and your pace at different effort zones. It also offers a run comparison feature to directly pit your current runs against past similar efforts.

Surgent is available for iPhone and iPad, making it accessible to a wide range of Apple users.
Surgent is free to download and use, with optional in-app purchases available for advanced features through subscription plans like Surgent Pro.
Surgent Pro offers a monthly subscription for $3.99 and an annual subscription at a founding price of $14.99. These plans likely unlock additional insights or features beyond the free version.
