Can’t turn of stroke rate in open water swim

1 star because the app does not allow the stroke rate to be turned off which is pretty damned annoying when you have 80 beeps per second going off in your ear during a relaxing swim in the river. I shall be negatively reviewing on social media in open water swim groups until this is fixed. I’ll try submitting a bug report but won’t hold my breath for responses to same.

App keeps crashing

Not Mrs Happy ,

Great when it works

I have had my Platysens for almost two years & am yet to get it to work in a pool. The unit has been replaced very easily once & the company couldn’t be more helpful.

It has in the past not uploaded swims to app.

Now the app is not showing any data & I am being asked to jump through hoops to answers. A to where all the swims I have done have gone & there are loads.

Like I said, brilliant when it works.
