FivePointFive: Breathwork for Athletes What is FivePointFive The world’s first breathwork app built for athletes—used by Elite Athletes and a fast-growing community of Everyday Athletes. We turn cutting-edge breathing science into short, coached sessions that strengthen performance and recovery, improve focus and stress resilience, and deepen restorative sleep. Built on science. Made measurable. Peer-reviewed research links structured breathwork with higher VO₂-max, improved HRV, lower resting heart rate, and better sleep quality. FivePointFive translates that science into sessions you can see working: - Live heart-rate in class to watch your autonomic nervous shift in real time - AI Performance Coach with post-session insights and coach tips - Trends over time across HR, HRV, resting HR, and sleep Train the full system: Mind • Body • Sleep - Mind: Downshift stress fast, sharpen focus, and rebalance the nervous system—in as little as 90 seconds. - Body: Build breathing mechanics and CO₂ tolerance to increase endurance, boost stamina, and speed recovery. - Sleep: Lower nighttime cortisol and deepen restorative sleep so you wake recovered and ready to go.

Verdict

The call

The clearest difference is in-app purchases: Project Function at none against FivePointFive's 5. Project Function also leads on device support (4 vs 2) and iOS requirement (15.5 vs 18.6). FivePointFive's advantage is update cadence (every 5 days vs every 6 weeks) and chart position (#83 vs unranked). On price and ads there is nothing between them.
