Frequently Asked Questions
Do I need an iPhone to use Spearo Apnea?
You need an iPhone to install the app, but once installed, Spearo Apnea runs standalone on your Apple Watch. No phone needed during training.
What are CO2 and O2 tables?
CO2 tables build tolerance to carbon dioxide by reducing rest between holds. O2 tables extend your max hold by progressively increasing hold times. Both are standard freediving training methods used by competitive divers worldwide.
Is this safe for beginners?
Yes. The app starts with conservative tables based on your current max hold. Always train in water with a buddy, and on dry land when training alone. Never train breath holds alone in water.
Can I create my own tables?
Absolutely. Set your own hold times, rest intervals, and number of rounds. The app also generates recommended tables based on your max hold time.
