Intensity scales every hold in the table: 80% for an easy or tired day, 100% standard, 120% for a hard day. Recovery times stay the same.
⚠️ Dry training only. Never practise breath-holds in water alone.
Max Hold Test
Dry, seated or lying down. Relax for 2 minutes, take one full (not forced) breath, then start the clock. Stop at your first breath — no heroics.

🛟 Safety & Terms of Use
Dry training only. Use HoldIt on land, seated or lying down. Never in or near water.
Never breath-hold in water alone. Shallow-water blackout happens without warning and can kill strong, experienced swimmers.
Never hyperventilate before a hold. It hides the urge to breathe without adding oxygen.
Never train while driving, bathing, standing, or anywhere a blackout could injure you.
Talk to a doctor first if you have any heart, lung, blood-pressure, seizure or other medical condition, or are pregnant.
Stop immediately at dizziness, tingling, vision changes or confusion. Tables and scores are not targets.
Under 18? Use only with a parent's or guardian's permission and supervision.
HoldIt is a training timer for informational and recreational purposes only. It is not a medical device and does not provide medical advice, diagnosis or supervision.
Breath-hold training carries inherent risks, including loss of consciousness, injury and death. By using HoldIt you voluntarily assume all of these risks and agree that you are solely responsible for how, where and when you train.
To the maximum extent permitted by law, HoldIt and its developer are not liable for any injury, death, loss or damage arising from your use of the app, and you release them from all such claims. The app is provided "as is", without warranties of any kind.
