Disclaimer: I've only used the app for two runs so far and am still using the free version. My big issue is with distance tracking. I don't know why it's so hard for the app to track accurate distances. All of my other apps will be in agreement on distance but this one is way off, despite adjusting the sensitivity. Even the different places in the app where it shows past runs don't agree on distances.

This app is a pretty good basic running trainer. That being said, there is absolutely no reason this should be a subscription-based product. It's a fixed program with no changes, no idea how they're justifying charging a monthly fee. This is the same program as Couch to 5k, which is a bit outdated, but is a one time purchase, as this type of application should be. There is also a pop up every time you open it asking you to rate 5 stars. Not give an honest review, but rate 5 stars.

Sorry to hear you were unsatisfied with the progress of the updates. We've added many new features to the app, but updated to a subscription model to provide the best value for our customers. Thank you for your feedback.

started a free trial, distance tracking doesnt work. now being billed monthly, tracking still doesnt work and its full of ads. Im trying to figure out how to cancel but its hidden well enough that I decided to take a break to write this review. garbage app, predatory business practices. do yourself a favor and find something else
