Turn your AxisBoard into a balance test

The Balance Dock holds your phone flat on the board, so the phone's own sensors read every tilt while you balance.

A score not a guess
Hold one foot for 15 seconds and the app returns a percentage for that foot — the same sway a therapist watches for, measured.

Both feet assessment
Left and right are scored separately and graphed separately, so a weak side shows up instead of hiding.

Progress you can see
Retest weekly and the graph moves. Every session adds to a record you can actually read.

Customers praised this balance measurement dock for providing objective progress tracking and real-time feedback. "Allows measurement of angles and gives feedback," making it excellent for physical therapy clients. However, several shoppers noted the magnet could be stronger to hold phones more securely, especially during dynamic movement. Some found setup challenging with unclear instructions and concerns about permanent phone magnets.

Clarity needed about how to attach to board

I am excited to use this dock but there are no directions nor obvious way to attach it to the axis board pro. I will need to call customer service which is why I’m marking it down several stars

Hi, sorry you had to hunt for this. There’s a video showing how to attach the dock in the Sidekick Relief & Recovery app, in the assessment section. You can get the app here: https://rehab.sidekicktool.com/

Thanks for flagging that it should be easier to find!

This is a very secure mount: the clamp, the pivot points, and the MagSafe dock are all rock solid.

This is an excellent way to attach a phone to the Ax

Great idea but my iPhone doesn’t stick to it at all. The device clamps onto the board well but unless my kit came without all the pieces there no way the phone stays attached to it

Hi there, we’re sorry your iPhone won’t stay attached to the Balance Dock, especially when the clamp itself works well. It may be missing a part or need a quick setup check. Please contact us with a photo of your kit, and we’ll help figure out what’s going on.

Magnet

Magnet is not strong enough to hold my phone at all.

Hi there, we’re sorry the Balance Dock magnet isn’t holding your phone securely. That’s not the experience we want you to have. Please reach out to us so we can help find a solution.

My physical therapist had long been a fan of the more old school wooden foot board. Then my orthopedic massage therapist recommended the axis board to me, and it combined with the balance dock blew my PTs mind and she’s excited to have data to use in tracking my progress.

Hi Kristina, thanks for sharing! We’re so glad the Balance Dock impressed your PT and is helping track your progress. Wishing you all the best on your journey!

This is a great product

This is a great product in theory, but I wish it had the capacity to hold the phone more secure so it could be used for dynamic balance activity.

Great first time experience

Love how secure this was to the Sidekick itself. The magnet could be a bit stronger to hold my phone, especially since initially, you’ll probably wobble around a bit. But

Bringing objectivity to the axisboard

Being able to objectively measure balance from side to side and from day to day is super helpful for our PT clients. It is also motivating for them to have a target to work towards. It is also helpful to have numbers for clinical documentation.

Not a fan

I'm not a fan of this product but it has potential if they made a new version. You have to put a permanent magnet on your phone to attach it the the dock which I don't want on my phone/case. The dock also doesn't attach fully to the sidekick if you have the knows at the top center. The countdown timer to start is too long and it's only set up for testing (15sec) not for a longer rehab type use (30sec - 1min)

Hi Anna, thank you for your feedback. We appreciate your suggestions and will consider improvements for future versions. If you have any other questions or need assistance, feel free to reach out!

Pretty good!

Really like the concept. The execution is good from what I can tell. More time will tell how reliable the score progression is with my ankle health.

The dock is a little hard to get on, and had to figure out to take off the magnet ring cover and my phone case for the phone to sit securely. Instructions a little unclear how high the other foot should be lifted, or if the phone needs to be at a certain angle (I figured no).

Seems good so far

I haven't used this item long, but my first test, I scored around 20% on one leg and 30% on another leg. I hope I see more progress as time goes by.

I have been having ankle issues and I was

I have been having ankle issues and I was grateful to see some science brought into the mix with an ankle strengthening board you could easily customize depending upon your ankle ailment. The phone holder is also sweet as it allows me to evaluate (again, scientifically, if I am making positive progress. Well done Sidekick!

Questions? We got you.

  • Do I need an AxisBoard to use the Balance Dock?

    Yes. The dock clips onto the board and the assessment reads the board's tilt. If you don't have one yet, add the AxisBoard to your order and get $6 off the Balance Dock.

  • How does the Stability Score work?

    You clip your phone and hold a single-leg balance for 15 seconds. The phone measures how much the board tilts and how quickly you correct it, and the app turns that into a percentage for that foot — so tests are comparable between right and left.

  • Which phones fit?

    Fits phones from about 5.4″ to 6.9″, and you can leave your case on. It holds your phone magnetically and clips securely onto your AxisBoard.

  • Which AxisBoard is this compatible with?

    The Balance Dock is compatible with AxisBoard 1.0 and AxisBoard 2.0
