The battery displayed issues since buying these in 2018 - no matter how much I charged the trackers they never reached 100%. I asked for a refund/ exchange within 30 days and their customer service told me it was just a software issue and they were fixing it soon with app updates.

Fast forward to today and I absolutely love the trackers and the app, it transforms my training and it’s gone through the roof. But right now, the trackers don’t even connect to the app, they’re sloppy. They keep disconnecting during the workout and one of them bleeds dry after every session, what happened to the supposed 7 hours battery life? (Actually, one of the app updates even got rid of the % battery life display, and were now left with a numberless bar, that doesn’t even make sense?!) Instead of enhancing my workouts it’s now hindering them.

Such huge huge potential let down by a total lack of design and maintenance. I appreciate it’s a work in progress but honestly Corner, how much time do you need to sort this product out? I love to use it but this is ridiculous, it’s been faulty since day one.

Hi Ninja!

Hope you are keeping well during these difficult times.

Just wanted to reach out and see if you are still having tracker related issues? If so we would love to see what we can do to help you get back on track with your training.

In the mean time you can download our updated app which has round timers which you can use even without trackers (all you have to do is start a session without connecting trackers) this will still log your exercise times and you can add goals to how much time you want to spend training.

Stay Safe and Best Wishes,

Team Corner

A brilliant product which gives great measurements to then aspire and try to improve on. When using them on my boxing bar and punchball they worked really well and measured accurately. However when using the reflex ball it definitely missed punches as the count was a lot lower than what punches were thrown.
I haven’t checked yet if there is one, but a good addition would be the 10 second warning before the end of the round, this would be of great benefit.

Thanks for your review! We are very happy that you’re enjoying our product, and don’t hesitate to shoot us a note at Hello@trainwithcorner.com if you have any questions.
