Location Tracking?!

I was setting up the kettlebell and had the location permission set to “When using the app”. I was trying to connect the kettlebell to the app, but had no success. It wasn’t until I enabled “Always allow” under location tracking that the kettlebell would connect to the app. That should not be necessary for a device that does NOT require CONSTANT awareness of my location. I switched it back to “When using the app”, so we’ll see if I encounter any other issues. But just the fact that this company requires constant tracking (to sell me data??) is unacceptable for a set of weights.

Edit: So after receiving the reply from Jaxjox, it appears constant location tracking is not required. However, I still had the issue, and multiple others, with connecting to the kettlebell and base. So I bumped up the review to 3 stars (from 1) and if they improve the connectivity, I’d increase the rating again. 🤞

Updated since December:

It’s been about two weeks since the update, and everything is now working like it should. Once the update arrived, I deleted and then reloaded the app to my iPhone and iPad. After an initial delay for syncing, the app not takes about 10-15 seconds to sync, and I’m in. Based training for triathlon currently, and this app an d kettlebell could not be better for building strength and mixing up my routine. Reps and weights recorded accurately, and the videos are useful and easy to follow. I would not highly recommend the kettlebell and app.

(Also - I brought concerns directly to the company, and received a call from operations with apologies and concern. She indicated at that time that the update was a week way. Got a call from her the next day indicating the update was available. She - and the company - stepped up and made it right. Things go wrong...thats life. What companies and people do when things go wrong indicate true intent. They stepped up. Most impressed. That said...please start working on ios 14 update! 😊)

Useless w/o Privacy Invasion

Updated: No Response, you can have your crummy products back.

Why does an app require my gps location to connect to a kettlebell? It doesn’t but JaxJox is forcing that you provide them with it before letting you use the equipment you already paid for. This is a shameless data mining technique and a lowlife business model. Bluetooth and WiFi are more than sufficient for a plethora of other devices that aren’t harvesting your private data.

How quickly can you let me use the equipment I paid for without data mining me because my return window is only 30 days.
