I've used this app twice before and it was great - I was regularly running 10-12k (nonstop). Now, after pregnancy & baby, I'm keen to get back to where I was, but unfortunately you now have to pay for it. I'm not willing to do this as I'm aware there are plenty of other free apps (and even an AI that could work a programme out for me!) out there. I'm quite disappointed 😞

Been using this app for a long time and it served me very well so It'd be hypocritical to rate it any lower. However this used to be ad-supported and you could go all the way to 10k for free. Now you have to pay a SUBSCRIPTION for even the base features. I was never going to pay for the Pro features (wasn't interested) but I would have been okay paying a one time fee for the 10k workout. Locking everything behind a ridiculous subscription is a fast track to losing your userbase. Dissapointing.

I used this app in 2015 and back then, it was perfect. The training plan was free and there was some kind of gold membership if I remember correctly, for those who want some extra features. Installed this app recently to find that the training plan is now a part of the subscription! How ridiculous! What used to be free should remain free. This only proves that your "extra features" failed to gain profit and now you have to charge for the free feature which is the only thing 99% users care about.
