BEWARE! It was a great concept but terrible execution. This company is not user friendly. It just seems to want to squeeze money out of customers at any given time and I've felt more frustrated by the app than finding it useful. The rules are not clearly defined at the beginning of use like the rule about "no shows" getting charged 20$ and late cancellations 15$!. It makes no sense to buy credits and then get charged more money when you don't make a class instead of just forfeiting your credits. People have kids and lives... things happen. Wasting their money and time is not very effective. Terrible customer service and Terrible company ethic.
But with any great idea... just like Uber and Lyft... someone will come alone with a BETTER version of this kind of company and I will gladly sign up when it becomes available. For now I'll go back to just having one gym membership that gets the job done.
