This is such a scam. There is nothing special about this, just regular dieting advice and program. DON’T loose your money, just ask chat GPT. It WILL come up with a better plan ! The customer service is awful.

I am trying to cancel the service for couple of weeks and instead of cancellation, I am charged more money every time I login in to the account. I already asked for a human assistant because their chat bot is not helpful at all. Their advises for how to cancel my subscription don´t work. I lost a lot of money and it is a nightmare so far. So please, do not sign for this app. I am now trying to solve this problem through my bank but it is so frustrating.

I wanted to look at this service by choosing their cheapest option.
They then added extra items at a price and had not stated that the cheapest option (7 days trial for a cosy of €7) became a subscription of much more directly.
I wrote cancelling immediately and they told me to cancel through the app which requires medical information i was unwilling to give. I contacted their help desk and they got back to me a week and half later asking for more medical details before agreeing to cancel!
They made the whole process difficult and, by delaying response, ensured I had passed their cancellation time.

Your health is our top priority, and we want the service to be safe and supportive for every customer.

Such a scam webite. Just to cancel subscription you gotta go through 100s of pages convincing not to do it. What unprofessional scam was this? Also not even approved patent and advertising it like something proud. Never again

I signed up for this website because it clearly stated a 30-day money-back guarantee. Within just a few hours, I realized this is not what I wanted and immediately tried to cancel. The cancellation process was complicated and did not work despite following the instructions provided.
I already got an email for cancellation and refund in 10 days i will wait and if its done I will happily remove my review too.
Thankyou
To make matters worse, I later discovered two charges on my credit card that I did not knowingly authorize. This is extremely frustrating and feels misleading.
If a company promotes a money-back guarantee, customers should not have to struggle to cancel or see unexpected charges. I am now forced to escalate this through my bank and consumer protection authorities if this is not resolved.

I would love to give them no star because its a shabby company with no ethics, I saw the add on instagram created an account and they offered trail and asked they will charge after that for 7 days but they charge me right away also for some premium as well which I never approved.
Now I asked them to refund me and they denied it saying its not in my withdrawals rights. There policy says 14 days and I started the account on 10sep and today is 14 sep.

Although I have cancelled my subscription and I received an email verifying it they have charged me 2 MONTHS from 19,95 euros. I wrote an email to them and I am waiting the return of my money and I asked them to delete my data from their database. Its very cheeky the way they do it. I wrote more emails to them and now I am waiting to see their reply. They only replyed to me here in Trustpilot.

I canceled my subscription back in June through their site. The site shows my subscription is no longer active. They continue to bill for reasons that my cancellation "wasn't due to a faulty product" so cancellation is denied.

Darryl,
Thank you for your review. We’re sorry to hear about the frustration with your cancellation. Once a subscription is canceled, billing should always stop, so the situation you describe is not how it should work. We’d like to look into your account details to understand what went wrong and make sure this is corrected.

Over 500 recipes to choose from based on my dietary needs. Every meal tastes amazing and keeps me full during eating windows. The shopping lists make grocery planning effortless. My family even enjoys the healthy meals I prepare using their recipes now.

I am pregnant. And I made this subscription by mistake. They stole me more than 70€. And they said 30 days refund and they refused me to refund me… They are thives… DONT USE IT. YOU WILL LOSE YOUR MONEY… Go as far as you can from this site. Is a huge scam. Only takes money.
New update 22/9/2025:
I think there is no worse website. Totally disappointed from them. They said specifically miss lucy customer care manager that I will have the refund in 10 days… It’s more than 10 business days and I still didn’t receive nothing please STAY AWAY FROM THESE SCAMS TO SAVE YOUR MONEY. And if someone doesn’t believe me I have all the emails… They play me…
Update:
They are continuing to win time… Unbelievable. I want my money back… THEY ARE REAL SCAMMERS. Don’t use this…

Hello,
Thank you for updating your review. We’re very sorry to hear that the refund has not yet reached you.
To clarify, because pregnancy was not indicated in your registration survey, our system did not trigger the automatic refund process for unfit health conditions. Your case was therefore handled manually, and we can confirm that the refund was issued on September 5, 2025. If you still haven’t seen it in your account, we recommend contacting your bank to check the status.
Our team will also send you an account report showing the refunded transactions to the same email address we’ve already used for our previous communication. You can provide it to your payment processor in your request for status check.

Subscription policy is unclearand all they want is money. I had a go and tried, however it wasn't for me so I cancelled it. Unfortunately after received cancellation email I was still charged money without any information. I found out only when I checked my account. I contact them, however they were not willing to help saying that I accepted policy and I did not cancel Subscription correctly. I am very dissapointed and I don't recomend it. Please, read before you accept anything.

I signed up for the 7 day trial for around $7. When I joined - there were many many pushy upgrades to buy more extras, over and over again. This gave me a negative impression about the site. I logged in once and chose not to do anything with the product. I did not log in again. One week later I received a charge for $39. At no point did I knowingly agree to this automated payment. I am sure they put it someone in the agreement - but it is not highlighted in any way - which is misleading. When I contacted them via email to refund this amount - they refused and informed me that I have to log in to the site and cancel my account. I did this and had to go through many pages of "are you sure you want to quit" - over and over again.
Even know I only logged in once and I clearly did not knowingly subscribe to a monthly charge - they still refused to refund the amount.
This is very poor business practice. I hope this information helps to prevent others for losing money to this site.

If there was a ZERO I would give it due to user experience being TERRIBLE. If you get this, don't try and cancel it because it will take you through multiple offers to stay on.
I am requesting my money be refunded because the APP DOES NOT RUN ON CHROME. Also, no app was initially offered when I purchased.
This is a money-making SCAM regardless of the fake reviews of people saying how great it is. Upgrade, upgrade, upgrade, every time it's a $20 upgrade for shopping list, consults, etc.

Absolute scam and breaches Digital Markets, Competition and Consumers Act 2024
Absolute scam - no app and breaches the Digital Markets, Competition and Consumers Act 2024 (c. 13) by refusing to refund within 14 days. Avoid at all costs.
Multiple emails with “Lily” in customer service. Refuse to acknowledge the refund request and constantly states “app” (there is no app!!) isn’t faulty so no refund. Have reported them to Action Fraud.
