You must be out of your mind if you work for Zenlabs and think I'm going to go from having the whole app available for free to paying a subscription; I'd rather have ads to listen to than have ANOTHER subscription to pay for. I've already found every workout on the app online and I'll just download a free interval timer to create the workouts going forward.

My previous rating was 5 stars, it functioned well as a free timer for simple run/walk intervals to help you get back into shape. now you have to pay for a subscription past the first four days. I don't want a subscription with whatever other "upgrades" exist. i was okay with hearing an ad or two in exchange for an easy to follow run schedule. If I wanted to pay for fitness I would have paid to join a gym. I'll be switching to a free running app in the future

Paid for weeks 3-9 as a one time purchase a while ago. Guess that's money wasted because they've switched to a subscription model and don't respect their past sales and obligations. Purchase means purchase, you don't get to revoke access to something I've paid for just because you aren't making enough money. Edit in light of their response: subscriptions add value to their bottom line, not customers. They saw an opportunity to extract wealth from you, the customer, not to improve their services
