I used to waste so much time checking apps and still showing up to bad conditions. Venturi fixed that completely. The forecasts are spot-on, and I actually trust them now.You can see who's riding where and get real-time updates from other people at the spot. The spot guides helped me find new places to ride that I didn't even know existed.Just nice to have everything in one place instead of bouncing between different apps.If you do any wind sport, this app is essential.
Developer Response
This is exactly why we built Venturi! Less time bouncing between apps and chasing the wrong conditions, more time actually getting on the water. We’re especially stoked to hear the spot guides have helped you discover new places to ride. Thanks for the awesome review and for being an early Venturi user!
No longer losing data!
Kite Kat
I previously gave this app 3 stars due to data loss when my watch would run out of battery and I lost accrued data in those sessions. The developer has addressed these issues, so I’m creating a new review to offset that one, thanks for addressing the problems! Love the app, specifically the gear garage, tack count and the plethora of wind sports to choose from.
Developer Response
Thank you for the feedback – we completely agree that losing a session is unacceptable. Both of the cases that you mentioned have been fixed, including saving sessions when the recording device runs out of power and syncing after longer sessions. We're glad you enjoyed tack counts! We are continually adding more advanced stats, so feel free to let us know what else you want to see. We really appreciate you being an early user, and we hope to see you back on Venturi!
Game changer

I'm more of a (foamie) surfer, but decided to give foiling a whirl once i saw it nuking at my local break (golden gate bridge) - OMG that current is no joke!! Ended up having to take out on a remote island in the pacific 10 days later where I have been accepted as a local🏄♀️ . Anything to get a break fromthe hubbie and kids 🤪. Thanks to Venturi for recording the whole sesh!
Love, Love, Love!!

There is so much to explore on the app! Helpful forecasts, gear suggestions, networking, session tracking and so much more. I feel like I can really maximize my time, and the features are practical and useful. Every time I open it, I feel like I discover something new and cool!
Developer Response
Thank you, we love hearing that you're exploring all of the features! Discovering something new every time you open Venturi is our goal, and there is plenty more coming 👀 Our favorite new feature of this week is emoji reactions to sessions. We're stoked to have you along for the ride!
Ocean currents and wave period come to the weather map, and you can now compare speed across rides.
Currents
A new Currents layer shows global ocean circulation from Copernicus Marine. Scrub or play the timeline to explore currents worldwide. Premium riders get the full forecast. This layer shows ocean circulation, not tides.
Wave period
A new Wave period layer colours swell period in seconds, with a tap readout. Switching between layers keeps the hour you were viewing.
Layers menu
Explore map layers with previews of each. The updated menu leaves more room for the map.
Weather map
Current and wave-period particles are brighter, with longer trails. Forecast frames load ahead of playback for smoother animation.
Compare rides
Activity details → Analysis lets you compare speed across sections of rides. Your saved recordings remain unchanged. Overlay full-session speed to compare rides and the gear used.
Spot pages
Spot pages now show the ocean gradient, with more evenly spaced actions, a clearer title, and an updated rating.
Recording
Phone recordings keep running while you navigate the app. Swiping back no longer leaves the recording screen by accident.
Rider badges
Rider badges now appear beside names in messages and feeds.
Today
The Today screen now features a daytime ocean gradient and a night sky.
Widgets and session maps
Forecast widgets now include a loading state and a retry option. Session maps better frame your track, including long rides. Map colours are scaled so a single GPS spike doesn’t turn the whole ride red.
