This is your biomechanics system — not affiliated with any other coach or trainer
check
It’s the most affordable option on the market, while giving you the most cutting-edge QB data available
check
It’s built to strengthen your business and your team, not take clients away from you
check
There’s truly nothing like it — unlimited biomechanics at your fingertips, from just a phone video
check
Your data is protected. We will never share or post your players’ results without your consent.
check
If you or your players want to share results publicly, we’d love if you tag us — but that’s completely up to you.
check
No trainer or outside coach has access to your data. SpinLab is strictly a tech and biomechanics platform built for you and your players.
check
Leaderboards: Only the top 20 players across the platform show up. If you have a high-level QB in the top 20 and don’t want their name displayed, you can mark them as anonymous in the settings tab.
If a player isn’t in the top 20, their name will not appear anywhere outside of your account.

Coaches on Option 1 can turn players ON/OFF each month using the Manage Players toggle.
check
You’ll only be billed for the QBs toggled ON that month.
check
Example: 8 total players on roster, 5 toggled ON = $50 that month.
check
Toggling a player OFF does not delete their data. When toggled back ON, all past reports and history are still available.
check
Fill the frame with the QB
check
Strong background contrast (avoid bright glare or dark shadows)
check
Keep the full player in frame
check
Don’t trim too early or too late
check
Follow angle and positioning outlined in the guide
check
The iOS app is designed more for players — it requires recording and uploading in real time, which can slow down training sessions and/or practices.
check
The web app is recommended for coaches:
1. Record all players’ throws on your phone during practice.
2. Upload later through the web app (fast and efficient).
check
Viewing reports is easier and more efficient on a desktop, tablet or phone via the WebApp.
check
Coaches can interpret the data however they choose.
check
If you’re confident in biomechanics, all the raw numbers and graphs are there.
check
If you’d like help, we provide a full Player Interpretation Guide.
check
Players and parents can also use this guide so everyone is speaking the same language.
check
Overall Throw Score → A measure of how much potential was reached on that throw (not a direct player-to-player comparison).
check
Acceleration Score → Looks at how explosive the throw is.
check
Deceleration Score → Looks at how smooth and controlled the motion finishes.
check
AI-Recommended Drill Library
check
Our AI engine recommends drills based on the last three throws a player uploads.

These appear in the Recommended tab of the drill library.
check
Coaches can use these recommendations, or ignore them and run their own drills.
check
Clipping too early/late.
check
Poor background contrast.
check
Not keeping the QB fully in frame.
check
Not recording directly perpendicular to the throw
check
Coaches are welcome to upsell biomechanics reports as a premium service for their clientele.

Reports and overlay videos must always keep the SpinLab and 3Motion logos intact.
check
Each player slot must be used for that individual only.

Creating one account and swapping in multiple players to avoid payment is not allowed. We can detect this on the back end.
check
Accounts abusing this will be banned immediately.
