### 3/5 — Enjoying Simfast

*2022-11-02, version 2.1.4*

Would love to see more slimfast products at my local walmart store in Sandersville Georgia.

### 2/5 — Doesn’t seem to track calories

*2022-08-05, version 2.1.3*

This app seems to be more like a food journal, since the calories taken in aren’t changing from 0 as I input food. Food journals are good, since you see how much you’re eating and all. But the numbers would be awesone. Because then I could make sure I was keeping in that range of enough to be healthy but low enough to lose weight… without having to use my calculator lol.

**Developer response:** Hi there! Thank you for bringing this to our attention. We have passed your feedback to our development team. We will reach out if we need more information to resolve this issue.

### 2/5 — Frustrating

*2022-02-15, version 2.1.0*

I have only used this app for 3 days but I’m already fed up with it.  I add an item to a custom menu & it doesn’t stay. I go out of the app & when I go back in, whatever I have added is gone. I really want this to work but this needs fixed.

**Developer response:** Thank you for reaching out. We apologize for any inconvenience this may be causing you. We will be sure to take this valuable feedback back to our development team. We will reach out if we need more info to help resolve this issue. Thank you again!

### 2/5 — Terrible App

*2021-12-26, version 2.1.0*

This must be one of the most frustrating apps I’ve ever used, so difficult to track meals as they disappear off the dashboard after you add them, calorie display does not deduct calories after adding foods, difficulty adding non SlimFast products and when adding no way to add the specific calories for that product. Extremely dissspointed.

**Developer response:** We apologize for any inconvenience this may be causing you. To better assist in helping you with this issue, and find out more information on what is occurring, please email us at appsupport@slimfast.com

### 2/5 — I hate this app

*2021-11-28, version 2.1.0*

Just started so giving it two stars for now. I despise the app. I want to be able to select the meal plan day I want every day as I will be doing the same one for a whole week. It won’t let me. I want to do meal plan day one, meal plan day 2 and in order just like that. I don’t want to have to dig for the plan I’m doing for the week and I want to organize it in that order. I’ve been on this app for four hours and can’t get it to do diddly squat.

**Developer response:** We apologize for any inconvenience this may be causing you. To better assist in helping you with this issue, please email us at appsupport@slimfast.com.

### 1/5 — So over this app!!!

*2021-05-26, version 1.8.1*

As many have stated before, this app is riddled with problems. Constantly crashes. Repeatedly deletes my Meal 1, so I have to re-enter it frequently. Every few days, deletes all my data from the previous days, so it looks like I’m just starting the program. Very disappointed. I would’ve expected better from such a well-known company. And if you read previous reviews, the post the same response: “please email us at....”, but it looks like the issues never get resolved.

### 2/5 — Great idea, Definitely needs some works

*2021-04-18, version 1.8.0*

I was excited to try this to assist with my plan. However, there are some major issues when trying to meal plan. It is not user friendly. You can customize your meal plan (which is not quick), then after you’re done, it hasn’t saved it or it messed up your choices.  It also double counts the calories on all slim fast products when you customize. There are also lists of recipes listed in the recipe section, but they’re no all available to add to the meal plan section, so you have to add them as a customized meal and then you’re back to fighting with the DIY. 
I will use the app for the progress and recipes sections, but the meal plan section is a loss for me and that is sad.

### 1/5 — Not user friendly at all

*2021-03-24, version 1.7.5*

I found this app & was very excited to begin a new journey.   My excitement turned to disappointment quickly when I attempted to log in my first shake of the day.   I just couldn’t figure out how to do it.   After trying several times to add my original cappuccino shake I gave up.   I want to do this plan, 2 shakes, 3 snacks, & one sensible meal.   However, until they fix this app I will find another way to track my compliance.     Don’t assume I am a novice.    I am very tech savvy.    Hope you fix this.

**Developer response:** We are sorry for any inconvenience this may be causing you. To better assist you in solving this problem, please email us at appsupport@slimfast.com. That way we can bring it back to our technical team to help aid in the process of getting this issue resolved.

### 1/5 — Not so good

*2021-03-21, version 1.7.5*

Won’t take a password to set up account I just can’t spend hour doing this set up

### 1/5 — Won’t load

*2021-02-12, version 1.7.5*

I sign in and then it goes right back to the beginning. I’m tired of typing in my email and password over and over.

### 2/5 — Logo

*2021-01-13, version 1.7.4*

I signed on and every time I hit the slim fast together app on my phone the logo comes up on a blank page and I can’t do anything. I don’t get it and it’s a waste of time for me. I did it so that I could do things on the run and track on my phone.

### 1/5 — Not very user friendly.

*2020-09-21, version 1.6.3*

Not very user friendly. Not easy to add meals or make recipes. I deleted it because I never figured out how to use.  It needs an instruction manual. No time for all that. Easier to write stuff down.

### 1/5 — App Bug

*2022-04-22, version 2.1.2*

If the app worked correctly it would be great, but it looks like a bug needs to be fixed. The application continues to close when trying to add items to my meal plan, which is annoying enough to make me stop using the app altogether.

### 1/5 — App doesn’t work correctly

*2022-01-17, version 2.1.0*

When trying to add food to the meal planner it keeps deleting the foods even an I am in dyi mode. It is very frustrating and I am about to just give up.

### 1/5 — Way too glitchy

*2021-12-02, version 2.1.0*

I’ve been using this app for less than 10 minutes and I am already fed up with it. It is extremely glitchy. I can see the great potential the app may have but right now it’s a total bust

### 1/5 — Failure

*2021-09-03, version 2.0.3*

Can’t even create account. Sad excuse for an app.

Update: After receiving email that a fix was completed on app for not allowing submission, tried again. Still doesn’t work; won’t set up profile. STILL sad excuse for an app. Just not worth the hassle.

### 1/5 — Grayed out app

*2021-08-27, version 2.0.2*

Can’t use app if you can’t log in after download.  Such a stupid app

### 1/5 — App doesn’t work

*2021-08-23, version 2.0.2*

No need to review as App doesn’t work or allow me to download.   Boxes are Grey confirming my age and if I read their forms.  Only box working is to bug me with emails.   Must lose lots of customers with inferior app.

### 1/5 — App

*2021-08-20, version 2.0.2*

Hi I’ve downloaded it on my Apple phone but when I try to log in it won’t let me accept the privacy and age things so I can log on please help me

### 1/5 — Doesn’t work!

*2021-07-06, version 1.8.2*

I just got the app and tried to set it up. It won’t complete the process after I entered all my information about 3 times! Frustrating!

### 1/5 — App does not work

*2021-06-29, version 1.8.2*

Tried using the app.  Selected a plan and added my details and nothing happens.  It goes back to the first screen and says to select a plan.  Select a plan, enter details, click on select plan and it goes back to the first page…. WTH
If I could loose weight going in circles that would be great!

### 1/5 — Doesn’t Work

*2021-06-23, version 1.8.2*

This app is a joke.  Won’t go beyond you putting in your weight.  No help whatsoever!

### 5/5 — Love new updates!

*2021-11-01, version 2.0.3*

I love the new updates and all the flexibility slimfast is now offering with its products! Cant wait to see whats next!

### 5/5 — Love the new SlimFast plans, flexible for all

*2021-09-15, version 2.0.3*

I love that the app now has plans for the whole range of SlimFast products with keto, favorite foods and low carb. 

The quiz was easy to get me started, it recommended the favorite foods plan, which was perfect for me. I'm a big user of the energy shakes in the morning and advanced after my workout for the added protein. I find many protein shakes taste weird, but I always look forward to my SlimFast! I have a more flexible diet and I like to have some variety a few times a week, so being able to hit the plus button and customize my plan was exactly what I needed. 😍

I made a few suggestions and I love the new updates, excited to see what else is added. So glad to have tasty SlimFast products and this app for my journey!

### 5/5 — Excellent Tool

*2020-01-20, version 1.4.4*

So much great information! The nutritional info, grocery lists and meal plans are phenomenal and a huge help, especially to those first starting out with a keto lifestyle.

### 5/5 — Keto Made Easy!

*2020-01-20, version 1.4.4*

This app definitely makes Keto easy with designed pre planned days and other really great features, like recipes, blogs and even weight tracker. It’s absolutely perfect for Keto beginners. Thank you SlimFast!

### 4/5 — Difficulty using app

*2022-01-17, version 2.1.0*

Having a hard time counting calories with app. After I save them they do not appear??

### 4/5 — SlimFast Together Review

*2021-11-27, version 2.1.0*

I am very pleased with the way the app spreads out my eating items and portions for me daily. I lost 13 pounds during my first two months. My progress may slow down a little now that Thanksgiving and Christmas are here, but I have developed some very good habits to carry me through this season. 
One minor frustration that I have with the app is that I have to log off then back on frequently to get up to date with my program. 
The recommended SlimFast products are quite helpful and filling and with my plan, I get a big meal daily, which I plan for and look forward to.
I recommend the app and hope others enjoy it as much as I do.
