MTL SURF vs apnia

The MTL SURF app provides live data on river metrics like the water temperature, the level and the debit. According to those metrics, you now have a hint at your fingertips to know wether or not the wave is good. The app also tells you if you should put on your spring suit or your full hooded 6/5 winter wetsuit. You can also watch if those metrics are going up or down one month back with line charts. Make sure to check the app before your next session at Habitat 67 or at "Vague à Guy"!

Apnia is a training and social tool—not a substitute for proper instruction, certified supervision, or safe diving practices. Never dive alone. Always dive within your limits and with appropriate safety protocols. Apnia is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Join the apnia community and dive deeper, together.
