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.

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.
