User Reviews

Most reviews acknowledge the hardware works and the app can control the device when it connects. However, widespread issues dominate: Bluetooth pairing/compatibility problems across iPhone models, a slow and buggy UI, weak support options, and limited in-app controls for switching settings. Connectivity, app reliability, and developer responsiveness are the primary pain points, with only a subset of users enjoying smooth operation.

Pros

Direct control of the device via the app, instead of relying solely on physical buttons.
When it connects, the pairing can be quick and reliable (instant connection for some users).
The hardware delivers EMS stimulation as intended for users who can get it working.
For some iPhone users, the app is easy to use and improves convenience by controlling the device.

Cons

Frequent Bluetooth connectivity and compatibility issues; many users report being unable to connect or receiving not‑supported/unsupported messages across various iPhone models.
App is slow, buggy, and has a dated UI with small controls, making navigation and operation difficult.
Lack of adequate support and broken or disabled developer contact; limited troubleshooting options and poor responsiveness.
Inability to reliably switch between settings or control modes within the app; the device often gets stuck on a single mode or fails to update settings.

Recent reviews

app is for multiple models of the same product, so I can only review based on the EMS I am currently using. Easy to understand. Timer is set automatically for 20 minutes. Wish that app was able to count down to zero onscreen while controlling the EMS device, so I could know when time is almost up. Instead it just stops with no warning when finished. Other than that, well done. Thanks.

This user face is near unusable… Why is it so complicated? Just give me some drop downs and adjustments. You don’t need to make it look so complicated… The text is way too tiny too, and the buttons are near impossible to touch with your finger. Someone needs to redo this heap

If you are looking to just control your device and use the app as a remote, it has everything you need and nothing more. I get it is a little out dated but honestly it’s not bad.
