Challenge Run is a fitness app that makes movement social and competitive. Every run generates a single score that captures how hard you worked — no pace charts, no spreadsheets, just a number your friends can understand at a glance. We're in early access and looking for runners who want to help shape tomorrow's competition platform — people who believe accountability is the best reason to lace up.






Available now on iOS (US App Store) and Android. iOS is currently US-only due to Apple's payment system restrictions — international iOS support is on our roadmap!
