This app was great. 2 years ago. Now it doesn't work without GPS (no, I don't want it to track my location, it's an app built around timing, it doesn't need that), and more importantly, the settings that are supposed to allow you to turn off its background data collection/cookies can't be turned off. Sure, the option is there, but if you opt out, exit the screen, and then come back, mysteriously all permissions have been granted again. So no. I'm not keeping this app. It's now a leach.

Thanks for your feedback. GPS is required for calories/distance, GPS map route, and more accurate voice alerts to prevent OS from killing a background app. We’d like to know details of the issue you mentioned. Please send the details or screenshot to contactus@zenlabsfitness.com. We'll pass it along to our development team for any way to improve.

this is not a free app. they trick you with a free download but if you want to continue past week 2 you have to pay $5.99 for 3 months or $14.99 for 12 months. skip downloading it. there are not enough features to justify that price in my opinion. I'd pay a one time fee if it looked useful but having to keep paying to get less than other apps? nope

This app was usable with just ads. Then, suddenly after week 2 it was not usable unless i paid, which is an obvious trick- get people started for free and then force them to pay if they want to finish. The app is no better than it was a few years ago when i did it, so I don't see that any improvements have been made to justify the change in accessibility. If I am going to pay for such s program , i will find one that is upfront about the cost.
