### 1/5 — Unusable

*2026-07-14*

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:** Hi there,

Thank you for sharing your feedback. We are very sorry to hear that you had trouble setting up your membership and that the purchase option was not working correctly.

We do offer the option to purchase your plan with Apple. We are sorry to hear you ran into issues with this. We completely understand how important a smooth and secure checkout process is, and we would love to help look into this.

Please feel free to reach out to our team at info@thefast800.com so we can investigate the issue and help you get started.

Warm regards, The Fast 800 team :)

### 3/5 — App keeps freezing

*2026-05-09, version 1.7.21*

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

### 5/5 — Working well for me.!

*2026-04-14, version 1.7.21*

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.

### 5/5 — Companion to weight loss

*2026-03-22, version 1.7.21*

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.

### 4/5 — Amazing recipes and workouts

*2026-03-12, version 1.7.20*

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!

### 1/5 — Disappointed

*2026-03-05*

Very disappointing & annoying that there is no notification/email to say subscription is due after 7 day free trail. I know I should have set an alarm or something to remind me but I only wanted to try for 7 days now I have $124 taken out of my bank! And what’s more… there is absolutely no way to contact someone to rectify it! Would be great if someone please contact me

**Developer response:** Hi there,

We are very sorry to hear about the frustration this charge has caused.

Please do reach out to our team directly at info@thefast800.com so we can look into this for you and offer further guidance.

Warm regards, The Fast 800 team :)

### 5/5 — Great app

*2026-02-24, version 1.7.20*

Great app that’s genuinely useful, easy to use and navigate. Not overly fussy, nicely designed. It’s really helping me with tracking my progress, planning meals & just generally keeping me motivated (which can be difficult when following a diet that’s hopefully going to become a lifelong commitment!)

### 5/5 — Health in your pocket

*2026-02-03, version 1.7.20*

Love this program, great to have the app on the go.

### 3/5 — Fast 800

*2026-02-03, version 1.7.20*

I’m finding it hard to stick to . I love the recipes.

### 5/5 — Exceptional

*2026-01-28, version 1.7.20*

The choices are very varied and exciting.  I have yet to find anything I didn’t enjoy!!!!
