  • App has lots of issues

    By ajordanbake
    For starters I love Katy and have been following her for a long time. I just recently purchased the work out generator for the minimum monthly amount and it had all type of issues. I often get a “Oops operation couldn’t be completed” sign when doing multiple tasks but especially when trying to do check ins (where oh update weight and pictures). I also thought it would store the workouts I logged so I knew what I done the previous week and it hasn’t. I have done 2-3 and none of them have shown up in my history. I even logged reps and weight. It’s just super frustrating because I love the workout generator, but don’t love dealing with all the app issues. My app is also up date.
  • So buggy and not worth my money

    By Kelise Nelson
    Honestly since I’ve had this app it’s been so buggy. I’ve had it for a year, but since this NEW update NOTHING WORKS. Checking in doesn’t work, uploading photos, reading coaches messages, going into the challenge work outs— NOTHING. Absolutely do not recommend!!! Additionally, your coach only responds once a week.. I’ve hired coaches where they respond whenever you submit a check in and that is way more helpful.
  • Great

    By pissedatsnap
    Love the app and that I can find all my programs. I have programs from 2018 that I love to do but The older programs no longer have the rest times for each workout.
  • Fall challenge

    By Callie475
    I would have given this 5 stars except my check-ins kept getting deleted. My final check in got deleted and I contacted support and still have not had a response since November 29th and now they announced the winners for the fall challenges. This was not my first check in to get deleted too. It happened three different times.
  • 1ST Challenge

    By huntinfitness
    This was my first time doing a challenge. I was unable to do the gym workouts but did the at home banded. I was truly surprised to see such a change in myself. The workouts were great and I loved the how to videos. The only issue I had was with the bands I purchased. They did not state numbers just light, medium and heavy, so I felt I was unable to really determine my progress on the app but I kept a separate log. The app is an easy one stop shop. Looking forward to my next challenge with team!
  • Fit By Katy App

    The FBK app is easy to navigate and aesthetically pleasing. I used the app for the first time to complete the fall 2021 challenge. I had no issues with the app and love that the app allows me to track the weight I used on exercises and would populate the weight as the exercise came up again though the 8 week challenge.

  • App Review

    By gpdco
    I rant and rave to everyone I know about the fit by Katy app. I love that there is a multitude of options including the work out generator for lower budget friendly users as well as a moderate option to follow past challenges. The forum during challenges are a little hard to use as you don’t get notified of responses to your posts and sometimes it glitches. I love the weight track feature and use this app everyday I’m in the gym!
  • My favorite workout app!!

    By ashleg_g
    This is by far my favorite workout app! Even when not doing challenges. I love how the workouts focus on muscle groups and offer videos on how to do each workout. I also love how you can track your progress — weights/ reps. It’s also wonderful how it keeps track for you! When you mark a workout complete, (the paid versions l), it keeps track so you know where to start next.
