How you can help

Help us build CENTERLINE.

Riders, coaches, studs, breeders, photographers, vets, physios, or anyone who loves horses: here's everything that helps us, in one place. Anything you can give is welcome, big or small.

Our promise: we only use what you send to test how accurate our scoring and 3D horses are. We never use it to train our software. We never publish it without your written permission, never share your contact details, and delete anything you ask us to.

1. Send a test video with its result

A video of one whole test, plus the final score % from that day. A photo of the score sheet helps, but it's optional, and you don't need to know the test name. We compare our scorer's early estimate with your real result to see how close it gets, and send you a free report.

2. Film your horse

About 30 seconds of video is perfect:

A slow walk all the way around your horse standing square, from every side
Then your horse walked and trotted in hand, straight towards and away from the camera, and side-on
Tell us the breed and height (and age if you know it)

Film in daylight on flat ground, with the whole horse in frame and the phone held level. Any phone is fine.

3. 360° photos

No time for video? Photos from all around one horse work too: front, back, both sides and the four corners, with the horse standing square. Breed and height, please.

4. Tell us what you think

What are you most excited to see in a dressage app? What would you never want it to do? Two lines is plenty.

Send it to us

Email videos, photos or links (Google Drive, Dropbox, iCloud or unlisted YouTube) to callum@centerlineequestrian.com, or use the form below and we'll reply with an easy way to send files.

Only send material you filmed or photographed yourself, or have the owner's permission to share. For riders under 18, a parent or guardian must agree. Want credit? Tell us how you'd like to be thanked.
