Buio brings personalized surf​ forecasting to your​ phone.

Remember that ​fantastic session last March at your favorite spot?
​Never again did it feel this good?

Out of all your sessions, Buio will be able to tell you exactly when wave size, swell direction, wind and tides are the same again, and you might be one of the only ones out, just because that online forecast didn't look that good that day....
Rate and track your sessions and grow your ​personal ​surf ​journal. Sessions keep track of the current wave data, local tide and wind.

Buio​ saves your sessions on your phone, learns ​from your ratings ​and suggests a good spot for your next session based on your individual likes and preferences.

Awesome App!

I used to log in my sessions on a notebook where I would write down the spot name, date, swell conditions, wind, tide and so on, but I would often forget the exact conditions and it was hard to use it for anything else. This app is way better. It is easier to annotate the session and it retrieves the exact swell conditions for the date and time of your surf. The best part it is that it learns what you like, (although it takes three or four logged sessions to start working) and recommends to you what spot is more likely to give you the surf you want. A nice feature is that you can share your session with contacts ( without giving away secret spots) and make them jealous or let them now when they are missing good waves. 100% recommended.

My favorite surf check and forecasting app.

Thanks to BUYO, i've been able to score some of my favorite spots practically empty. Being able to rate sessions based on my experience and preferences according to the conditions AND get notifications of predicted conditions according to my preferences is so much more helpful compared to what surfline or other surf forecasting sites say.
