Holistic, Science-Backed Weight Loss That Actually Works!
Jwoflava
Yes, the app freezes occasionally and might need a reset (let’s work on this dev team), but honestly, this is the best weight-loss app out there. It’s backed by science, offering not only physical exercises but also mental health tools, recognising that weight loss is a holistic journey involving mind, body, and spirit. Changing behaviour takes time, and this app supports that process beautifully.The recipes are fantastic for breaking unhealthy habits—do they taste like cheesy fries? No, because cheesy fries are engineered to taste amazing while offering zero nutritional value. The point here is resetting your taste buds, and it works.Both my partner (male, 29) and I (female, 32) have lost significant weight in the three months (25lbs and 22lbs respectively - and kept it off). As someone with PCOS, I’ve struggled to find something effective, but this programme delivered real results. Highly recommend!
First Week
Happy to hope
Immediately made me realize how to enjoy food and feel better
Unusable
Southern Roots
This app is unusable because it doesn’t actually have an IAP option. It makes you purchase all the plans off the app, and the website prices are different than the prices listed under In App Purchases. My bank flagged the website as being untrustworthy, so I actually wasn’t able to purchase a membership. If this app had the function to buy plans through the apple store, I would trust it more. but the lack of In App purchases makes this company’s app useless.
Developer Response

Expensive
JNay0813
$330/year or $40/month. No thank you. I wanted to try the free version to see if paying for it would actually be worth it, but the free trial requires you to add payment info so they can bill you after 7 days. I personally would prefer to try it out for a bit before committing to paying for it.
Developer Response
Hi JNay0813, thank you for your review. We are sorry to hear of your experience using the Free Trial via the App. Whilst payment details are entered as part of registering an account, you are only billed if the account is still active after 7 days. We appreciate your feedback regarding trying the App before entering payment information, and have noted this for our development team. Kind Regards, The Fast 800 Team :)
