Unusable

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.

App keeps freezing

Hi,
Not sure if it’s just me but I’ve had to download this at least 3 times in the last month. It just freezes on me. Realise this is quite an old app as I first started using it in 2022. I find the diet menus and exercises helpful and they have helped me to loose weight which is why I keep coming back to it but frustrated with the freezing

Working well for me.!

I have been using the Fast800 diet plan for a month and I am losing weight. The recipes are tasty and the information I receive as part of the plan helps me to understand the science. I’m very happy with my results and looking forward to reaching my goal.

Companion to weight loss

I have so enjoyed the variety of recipes. Following the meal plan and shopping list has made my life as a full time worker, Mum and home marker easier. Whilst also focusing on healthy food and weight loss.

Amazing recipes and workouts

Love this app, really helped me to trim down and get fitter. The only thing I would add is please can there be a no music option version of the work out please? I’d like to listen to my own music over the top. Thanks!
