Common questions

How do I get the best analysis?

Film from the side. A camera level with the wave face shows your stance and turns far better than one filmed from behind.
Get close. Aim for the surfer to fill at least a third of the frame height. Trim or zoom the clip before importing.
Use one wave per clip. Short clips of a single ride work best.

If you were small, distant or unclear in a clip, some technique numbers are skipped instead of guessed. A closer, side-on clip unlocks the full breakdown.

Where do my clips come from?

Any surf video works: your own footage, a friend’s filming, or clips AirDropped from the beach. Tap the import button in the app to choose them from the Files app. To use a clip from Photos, save it to Files first.

Do my videos get uploaded?

No. Analysis happens entirely on your iPhone. Full Coaching sends that wave’s numbers and still frames from the clip (a few wide shots and close-ups of you), never the video. See the Privacy Policy for details.

What’s free, and what do credits buy?

Analysis, stats and Quick Take coaching are always free, and they run on your iPhone. Full Coaching studies photos of your whole ride, wide shots of the wave and close-ups of you about every third of a second, and gives you an overview, timed moments to watch, what’s working, and fixes with drills. It costs one credit per wave. Credits come in packs of 5 and 10.

How do I watch my ride with the coach?

Open a wave that has Full Coaching and tap one of the Moments to watch, or open the video full screen and turn on With coach. The player slows to half speed just before each moment, pauses on it with the coach’s note, then carries on when you tap Next moment. Scrubbing or tapping a marker on the timeline leaves the mode.

What do Follow and Rider do in the player?

Follow zooms in on you and moves with you through the ride, which helps a lot with clips filmed from further away. Rider draws a box around the person Carvesense is tracking, so you can check it picked the right surfer.

The coach said something that doesn’t match my ride

Coaching can only be as good as what’s in the clip. A side-on clip where you’re large in the frame works best. If something still looks wrong, use Coach Again (Quick Take is free), or email me the wave’s date and what was off. It genuinely helps improve the coaching.

Do credits expire?

No. Credits never expire.

I bought credits but my balance didn’t change

If the purchase went through but the credits haven’t arrived, they’ll be added automatically the next time you open Carvesense with an internet connection. If they still haven’t appeared after that, email me with roughly when you bought them.

Will I lose my credits if I delete the app or change phones?

Credits are tied to an identifier stored in your iPhone’s Keychain. That identifier survives deleting and reinstalling the app on the same phone. It also moves to a new phone if you restore from an encrypted iCloud or computer backup. If you set up a new phone some other way, email me and I’ll help move your balance.

Quick Take says it isn’t available

Quick Take runs on-device using Apple Intelligence, so it needs iOS 26 or later on an iPhone that supports Apple Intelligence, with Apple Intelligence turned on in Settings. Just after it’s turned on, it may need some time to finish preparing. If Quick Take is unavailable, analysis and Full Coaching still work.

How do I get a refund?

App Store purchases are refunded by Apple. Request one at reportaproblem.apple.com.

How do I delete my data?

In the app, go to Settings › Delete all data. To export everything first, use Settings › Export my data. To have your credit record removed from our server, email me.
