This is not something I was expecting or thought I would have had

  4. [R13] Fitness Coach 2/5 · US This is great but there’s one huge thing: I was in there to get a quick way to get fit for free and have ways of knowing what food to eat for it, but the thing is, I don’t have a lot of the ingredients to the foods for each day, I know that’s my problem but still. Once you get to like day six which if you skip a few days it just keeps going with the workout days, so then when you log in and it say
  5. [R4] Fitness Coach 2/5 · US This makes me frustrated!: Can someone tell me how to carry on after the question that says “How do you consider your current fitness level?” Because it keeps on bringing me to pictures of random users and I can’t get off the screen :( I was looking forward to using this app
  6. [R15] Fitness Coach 3/5 · US Good But: The fitness coach app was good don’t get me wrong. The workouts were easy it was good at showing what to do but when I was going to do my second day to work out, it tried to force me to do a free trial in no matter what I tried to do to try to get out of it I couldn’t do my work out or do any of the other challenges without a thing popping up saying that I have to sign up for the free tr
  7. [R26] Fitness Coach 5/5 · US Great app!: I think that this is a really great app because it tells you to drink water tracks it and also uses the Health app to help it when you want to stop it says stopping is not an option. I think that was very good because it really just helps and you can lose weight and do many more things and I like that when you’re on the out that you’re doing it silent and it shows you how to do it and

  9. [R11] Fitness Coach 5/5 · US Amazing!: Meets all my expectations! I love this app, I feel great everyday after I finish my workout.

  10. [R17] Fitness Coach 5/5 · US Brendalid Hernandez: I’m losing weight day by day it’s awesome. When I was in 3rd grade I was body shamed and bullied because of the way I looked. I was traumatized since I was a kid and now I’m insecure about my weight and this app helps me so much with my weight loss and feel a little better about myself. Hope people can give this a chance and see how much it could help them to whatever problem
  11. [R19] Fitness Coach 2/5 · US Ehh: Yes, you have to pay. But it gives you pretty much the same workout routine every week and it break down a lot. So there are some days when the app doesn’t even open or in the middle of your workout it just stops working.

  14. [R7] Fitness Coach 2/5 · US Stop with the premium: I can't even do a workout without it asking for premium and that much every week is stupid. Stop using money so we can look better
  15. [R9] Fitness Coach 3/5 · US Decent for free: I mean if your looking for a free workout app that you don’t (have) to pay for, this is it.

  18. [R70] Muscle Booster Workout Tracker 2/5 · US Great app, poor support: I’ve used this app for nearly 2 years and had great results with the workouts. Seems like if you have a technical problem you’re on your own. The app just stopped working one day. Probably from the latest update. Reaching out to support for several days just got me automated emails pointing me to a FAQ. Following the guidance in the FAQ made the issue even worse. A
