Terrible

I have tried countless times to video tape one serve, analyze and wait and wait and wait. I have more than half of my videos still being analyzed!

I want my money back!!!

Response from developer

Thank you for reaching out — we’re here to help! The issue you’re experiencing is often related to an unstable or slow internet connection. We recommend testing your connection using a speed test app or website to ensure sufficient bandwidth. Also, the camera setup is important; the whole player needs to be in the camera while holding it still. With good internet connectivity, the analysis should take between 3-9 seconds. Please send us an email so that we can assist you: support@sevensix.no

Cool but glitchy

When it works it seems cool and possibly helpful but it would be nice if we could use the front camera. Also the camera may work at first use then if I try to record another trial the camera isn’t working. I have to exit out and restart the trial for the camera to maybe work.

Doesn’t work

I subscribed for one month, 0 analysis so far after 10 recorded videos. Waste of time and money.

Low quality
