SlimFast app that’s only for its Keto Products

I am a dedicated user of the SlimFast program but I really am frustrated that the ONLY available SlimFast app is solely for their ketogenic products. I flexibly use the SlimFast original, high energy and advanced formulas coupled with a well-balanced primary meal of the day. Most health professionals do not recommend the ketogenic diet since its very high fat and low carbohydrate components are not healthy in the long term even if weight loss does occur. Regardless, this application only provides for the exclusive use of SlimFast keto products and does not allow for substitution of the other SlimFast formulas. So, it’s pretty worthless if you primarily use the non-keto formulas.
I would love for SlimFast to broaden/modify this app and allow for its wider range of products. I would then be happy to use this application as part of my weight loss program. Come on SlimFast, fix this!

Thank you. We appreciate your feedback and concerns. The SlimFast Together app is designed to make Keto easy. Our pre-defined daily menus are intended to take the work out of Keto meal planning. We are currently working through monthly updates with enhanced features and your feedback will certainly be factored in. Stay tuned!

Great idea, Definitely needs some works

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.

Great Keto products but app still lacking

First of all I think it’s great that SlimFast has brought various Keto products that are easy to use and I use them all. Unfortunately the app is lacking in my opinion in one main area. First what is with the meal plans and why do I have to pick one then edit it? Why not give the option of filling in a blank meal plan and the app just subtracting away the macros as I fill in each meal. Sure I can edit a meal plan and do the same but why should I need to.
The glimmer of hope in this app is the recipes and that is where this app really shines and gives a lot of really great options.
