Sweat with Kayla app being the guru for fitness freaks, has become a faulty app amidst its fans. Fans are furious for allegedly overcharging for the workout app.

Kayla Itsines which has over four million fans and followers on Instagram has been charging them unexpectedly and the subscription fee is impossible to get out. People reported that, Kayla die-hard fitness fans can download the app, Sweat with Kayla, at no charge from the iTunes store, and get a free, seven-day trial.

The 7 day trial by Kayla will help to check out the exercise plans, workouts, meal plans and more. But to even get that trial, users have to put in their credit card details and information. After the trial period is over, the users get charged $19.99 a month unless they cancel the application before the trial gets expired. 

One of the users wrote on iTunes saying, "The cancellation process and customer service is horrendous. I cancelled after 2/3 days, well before the trial expired, but due to the auto-renew, am on the hook for the months I didn't realize the app was still active." 

Post the trail session, fans find it difficult to cancel the app and stop paying the subscription fee and finally fall victim to overcharging. Racked reported that during the initial time of app launch, Sweat with Kayla told its fans that it is listening to every users' concern and that it was looking forward to evolving the product even further in the coming months.

Whereas, now the fans and users say that they do not attend to customer needs and complaints. According to Business Insider, one of the reviews by another user on iTunes store said that, "I sent several emails about a problem with the app. No response. Kayla launched an app and completely forgot the customer service aspect." Some other customers have said they have tried to contact customer support but have been unable to get restitution. Angry customers have now turned to Instagram to get the attention of Ms Itsines.

Meanwhile, Ms Itsines' public relations manager Bec Sealey told The Courier Mail the team had not received any complaints about privacy or cost issues and has advised any customers with concerns to contact them directly.

The 24-year-old fitness mogul grew to fame after releasing Bikini Body Guides to women across the globe before launching her app.

Subscription to such services often falls into criticisms. Fabletics and Adore Me are on such retail companies which have been fired for recurring charges. Sweat with Kayla app still scores positive reviews and says it has plenty of loyal fans.
