### 1/5 — Still can’t create a login

*2021-10-15, version 1.4.1*

Seems like you’ve had this problem for quite a while. Ru planning on fixing it?

### 1/5 — Can’t Register

*2021-03-03, version 1.4.1*

Just received the device today. Tried to register with app but was constantly rejected. What do I need to do to get program?

### 3/5 — Needs more games

*2021-02-11, version 1.4.1*

I’m enjoying the core challenge m-trac gives me despite some issues with freezing. I think it would be great if they’d update with new games, however.

### 1/5 — iPhone support

*2020-11-26, version 1.4.1*

The photo displayed says coming soon but that was over a year ago. Will there ever be support for the iPhone app?

### 1/5 — Disappointed

*2020-09-24, version 1.4.1*

The app does not allow you to create an account. In addition, it does not pair the names of the exercises with graphics to show the how to properly do each exercise for user to follow along.

### 1/5 — No dice

*2020-05-02, version 1.4.1*

Using an iPhone X, wasn’t able to login, create an account, login using Facebook or cast to chrome cast. I reached out for support but haven’t heard back in about a week. I tried the link for support in the app but that link is also broken.

### 3/5 — Screen mirroring works in Apple TV no account though

*2020-04-23, version 1.4.1*

Screen mirroring works great on my Apple TV. I tried the exercises and they’re very challenging which is good. This was much cheaper than a bosu ball so I went for it. I really wish I was able to make an account so I could record things and measure abilities as advertised and have them save. At present I cannot make an account. Please fix this feature.

### 1/5 — Doesn’t work

*2020-03-26, version 1.4.1*

I downloaded the app after buying an m trac pad from tj maxx and I tried signing up and i keep getting a “not active” error message.

### 1/5 — Doesn’t mirror screen to TV

*2019-07-22, version 1.4.1*

This device is useless, it won’t mirror my phone screen to the TV... my other apps work fine w google chrome, this app does not. The only way to use this is to stare down at the phone on the M-Trac board. Very disappointed!

### 1/5 — Love the idea but app needs work!

*2018-03-10, version 1.2*

I would have been better if the app was a great as the piece of equipment I’m having trouble with the screen mirroring
