Heart rate variability, made practical
IncreaseHRV is a free, guided 4-7-8 breathing tool. HRV is one of the best signals of how well your body handles stress and recovers, and slow, paced breathing is the fastest lever you control. Run a session in minutes, no account needed.
Higher HRV is linked to better stress resilience, recovery, and long-term cardiovascular health.
A slow inhale-hold-exhale rhythm developed to calm the nervous system in just a few cycles.
Set any session length up to 3 minutes free (20 with a subscription) and follow a visual pacing guide.
Anyone can open the breathwork tool and run a session, no sign-up required. If you want to see your consistency over time, log your own HRV readings day to day, and get gentle reminders to practice, create a free account and subscribe for a small monthly fee.
IncreaseHRV is an educational tool, not a medical device. HRV values you log are self-reported from your own devices. Consult a clinician for any health concerns.
