POOR. You signed up a trial; they hook your credit card and don't let go. I used paypal and after every payment emailed and received no response. They are under a few names: Fasting SIA, Nutrofasting, Certified fasting, Nutrameg Sia. I finally got a response and they offered no refunds whatsoever.
Quite a scam. The program was not used 1 day.I never logged in. I didn't even dowloaded the app.

Cancelling this subscription is like trying to cancel Foxtel in 2008. No clear cancel button, vague instructions, and enough hoops to qualify for the Olympics.

Absolutely a scam!!!!!
I regret not reading the reviews beforehand. I was attracted by a small initial payment, but after that they kept charging my card repeatedly without my consent. I only discovered this when I checked my bank account.
If this happens to you, block your card immediately!!!!!! Even after I blocked mine, they continued attempting to charge it multiple times. Thankfully, my bank declined the transactions, but the repeated attempts were extremely concerning.
This is an untrustworthy websit! Do not sign up for this disgusting service! Stay away!!!

I did NOT knowingly agree to a $39/month subscription. I initially paid a small one-time fee (a few dollars) to try the service. At no point was it clearly communicated to me that this would automatically convert into a recurring $39 monthly subscription.
Shortly after, I noticed charges of $39 being deducted from my account. This feels extremely misleading and non-transparent.
When I attempted to cancel, the website displayed a message stating that I would have to pay an additional $195/$199 if I leave now. Being pressured with large extra fees just to cancel a subscription is unacceptable and raises serious concerns about the company’s practices.
Customer support confirmed the active $39 subscription, yet the cancellation page attempts to impose further charges.
I have documented everything and contacted my bank to dispute the payments. I expect a full clarification and proper cancellation without any additional charges.
Based on my experience, I strongly advise others to carefully review what they are signing up for.

Literal scam, can’t give a refund when it wasn’t even me subscribing, makes it extremely hard to unsubscribe either way, and has garbage support. Keeps trying to take money from the card even when unsubscribed. Never even go near this app, will steal your money.

I lost more weight trying to cancel my subscription than following the app itself. Fear always the app where you are able to subscribe in few steps but cancel in zillion steps. I would say this app is by far the first one in that list of apps.

Certified Fasting activated an abonnement without my knowledge or approval. No links or information on the website about terminating the abonnement. Avoid at all cost.
Edit: after some searching I was able to find a termination option for the Nutrition subscription. While this did require going through a long series of retainer questions - any of which answered incorrectly ("no, I have not completed the first seven days") sent me back to the initial subscription - I was able to terminate the subscription. In parallel, I had sent an email to the helpdesk and contrary to other people's expectations got a rapid response stating that in addition to the nutrition plan, also a premium plan was active. The termination link wasn't immediately obvious (and ended in "premium_upsell"), it was possible to terminate the premium subscription with a couple of clicks. The plans are still accessible until the end dates in March and May, respectively :(
In short, unpleasant experience but at least they responded quickly.

This site is an absolute scam. They con you into purchasing the plan, and then when you get in to your profile, you get absolutely no features unless you purchase additional features for $19.95. And everything is $19.95 individually so by the time you get a nutritionist of fasting plan and food recommendations you’re up to $60. I accidentally pressed on one of the features it charged my card immediately and I emailed customer service. They refused to give me a refund be very careful when looking into this app you can get better information on YouTube for free.

One of the worst experiences!
First of all the price increases 3 times more after the 1st month. Then they charge for some extra things and it's almost impossible to cancel it- I canceled all my subscriptions in November, December was calm and today they again charged me with 40 euros!

After deciding against using their services I asked to be unsuncribed from their emails. After the third time clicking unsubscribe I was still receiving emails. I emailed them to ask them to delete my data and close account and no longer wanted to receive anything. A week later no response and another email. I went on to live chat saying they no longer had consent to use any of my data and it should be deleted and not one person has come back to me. They are now illegally holding and using my data. I wouldn’t bother even following the quiz.

AVOID THIS APP!!! If I could put zero stars I would. I purchased the app and realized that it's not worth the amount of money I payed. I payed $80 just to count the hours I eat and don't eat. A total rip off! So I tried to canceling the subscription that same day and was told that refund is only possible if I use the app for 10 days and see no result. What bullshit is that? If I'm canceling it the same day they should return the money. I was told by a robot that a member of a team is going to connect with me in the next couple of days. I've been emailing for a few weeks now trying to get a human to reply to me but with no luck. They are complete scammers and I wish I would've read the reviews prior to purchasing their plan. Every bad review is 100% true do not fall for these scams!!

I have charges from this website I never consented to. No idea what the service is, just googled and the only way to unsubscribe is through logging into an account I never had! Their customer support is non existent and they don’t respond via email. The only option was to cancel my card. Not sure from where they stole my information but I’ll be filing a complaint.
