Latest update · v20.3
What the developer says changed (the verdict above weighs this against what reviewers report):
Bug fixes and performance improvements
Recurring themes
Who it's for
Fitness AI is for beginners and intermediate lifters looking for a structured strength training program and workout tracking R44R96. It's also for those who appreciate guided exercise demonstrations and progressive overload R19R27R85. It is NOT for users who prioritize a wide variety of exercises, cardio, or custom workout options R4R24R38. It is also not for users who are sensitive to high subscription costs or who expect seamless subscription management and bug-free performance R1R2R5R6.
Evidence note: The recent reviews skew heavily negative, particularly regarding subscription issues and bugs, which contradicts the high lifetime rating. The developer's release notes mention 'Bug fixes and performance improvements,' but recent reviews directly contradict this, with many users reporting increased bugginess and freezing . This suggests a downward trajectory in user satisfaction.

- [R19] Like a gym partner: This app a gym partner. I used to carry around a small pad of paper and write down the amount of reps the amount of weight so that I could keep track this that makes it a lot easier and even makes suggestions on when to increase. I’d recommend this for anybody newbie or veteran
- [R27] Changed my life: This is a great app, I’ve been using it for a few years and it’s made such a difference. I did know my way around the gym before using it, having seen a trainer years before, but the diagrams are useful even for beginners. One area of improvement: as I get more experienced- and let’s face it… as I get older - I find that I need to manually update the weight and rep increases. I f
- [R28] AWESOME GROWTH: I’m on my 3rd real consist month of this app. I am absolutely WOWED on my progress and gains. My body looks completely different and I already have to buy new clothes to fit into. I am so happy I finally decided to give this a real shot. I have been trying to get this progress for years. Now thanks to the app it’s actually happening.
- [R85] On my way to a healthy retirement!: I started this app with my husband using his routine and loved it! It shows you how to do each one correctly and gives tips. Love that it shows the muscles you are using and working. It’s been 6 months and I’ve seen results in body shape and weight loss. Now purchased my own app and love the ease of recording rather than using my notebook, love that I can work o
- [R44] Game Changer!: I first started going to the gym about 8 months ago. With never having been to a gym in life. This app has helped me understand the workouts and has taught me how to plan my own. Now I actually don’t feel like I need to even have the app. It has opened up my life to the joys of working out. I honestly don’t know where o would be without it. Sure there are other apps that could have
- [R96] Great for beginners and advanced: I started using FitnessAI back in 2019, and it completely changed my approach to working out. I used to avoid the gym because I had no idea what I was doing and gave up easily. This app made fitness approachable and motivating. It has something for every level, beginner to advanced with all types of workouts, cardio, HIIT, strength, etc. Best part? It learns your
- [R72] Awesome: Awesome app tracks weight from previous workouts and plenty of alternatives. Create your own workouts or let it do it for you.
- [R109] Excellent App: I absolutely love this app! It effectively tracks my workouts and weight, and the exercise recommendations are exceptional. The coach assistance is definitely my favorite feature, it feels like having my very own personal coach right at my fingertips!
- [R269] Good app but has its faults.: This app has it’s good and bad points. Good:A) A good range of exercises. B) Clear guide on how to do them correctly. C) After 4 workouts it customises your workouts to what you’ve already lifted. Bad: A) I do my workouts at home and there is no option for alternative exercises (e.g lat push downs). Instead the app tells you to not to do them! B) No warm up or cool d
- [R34] 👍: Great product. Great way to track and schedule lifts. Good customer service.
- [R234] Decent: Pros: Randomizes workouts somewhat so that it is not exactly the same routine Interface of watch app is probably most appealing across other apps I tried Quick replacement of exercise in the routine with a similar one is a pretty neat feature. Helps when machine which you want is occupied Cons: Watch app is merely a remote for a phone app. Can’t use watch only Watch app freezes at least o
- [R257] Daniel: You can adjust to what you’re currently lifting at, and there are a variety of options to suit. Could do with more exercises! Very good for keeping routine!
- [R1] Super shady!!! Do not download!!!: I downloaded the app, started the three day trial and then decided that it was not a good fit for me. When I went to cancel it, it was almost impossible. The website states that you either cancel it using the gear icon to get to membership settings In the app or your iCloud subscriptions. Neither were available for me. I ended up having to go to the Fitness AI w
- [R2] Fraud: I have tried to cancel this app since i got it and it will not cancel. I reached out and i do not want to be charged. This is horrible!!!
- [R5] Can’t unsubscribe: I just got charged for a new year’s subscription, but there is no way in the app to cancel and no way to contact the company to cancel the subscription. It isn’t handled by Apple so can’t cancel in the normal way through phone settings. Really sketchy behavior all around. I’d like a refund and a way to cancel so it doesn’t happen again.
- [R6] CANT CANCEL: I got the free trial of this app, but I did not want to proceed with the membership, this app has no option to cancel membership within app, or even through the website. I couldn’t even cancel it through my settings/account/subscriptions. I receive no email on my confirmation of free trial or subscription. I ended up getting charged $90 for an app and membership I don’t want, I do not
- [R21] App has a bug: It won’t let me log workouts and I paid for premium so it’s super annoying will delete if it doesn’t work by tomorrow.
- [R25] Latest version 16.0 unusable: Unable to add a new exercise. Unable to start a new day.
- [R33] Can’t report: I looked all over the app and the website to find a spot to say this, but it didn’t pop out at me so when I was trying to do the 45 day calorie burner challenge that they have it wasn’t saving my progress from set to set so I stopped participating. For referenc I’m using a iPhone 16 Pro that’s fully updated.
- [R36] Glitchy and freezes in between sets using watch.: This app does not work as well as it thinks it does. They charge you money for an app that does not work well with my Apple Watch and freezes all the time to where I have to pause my workout just to get it working again. Logged back in today and now they are charging just to log sets uninstalled it and will never use it again. Save your money and u
- [R4] Average: I like that it compares me to others in my weight and age group. It’s easy to track your workouts. It doesn’t have cardio. It also doesn’t understand warm up sets or pyramiding, or working to failure. You need to do every set to a certain rep count and weight or it will consider it a failure. The AI just isn’t intelligent. This could be a great app in a year or two if the developers stick
- [R20] Great for Beginners: I have been using this app for 4 months now. As someone who has lifted for 12 years and worked out with a trainer I was looking for some variety in workouts I now structure myself. I have found that it feeds the same exercises and either has 9 reps or 10 reps - it does not seem to be personalized - very cookie cutter. The options do lack some very basic exercises or machines
- [R24] Needs more cardio: If you like to incorporate cardio to your workout, this is not the greatest app. Overall, great selection for weight training.
- [R38] 4 star!: Great app for tracking workouts, I’ve used it twice so far. One star less, though. I wish they had more kettlebell exercises; there are only five in the app. It would also be great if there were a way to add our own exercises that aren’t part of their database.
- [R7] It’s great: Now quit asking me to write a review. I should not be asked after every workout
- [R16] Ruining a good thing: I use to love this app but you are disappointingly destroying what made it good, which was simplicity and distraction free design. Now you are spamming me with stupid challenge pop ups that I have to x out of every time I open the app. Also I had messaged support a little while back that the one thing that would make this app better would be the ability to add custom exerci
- [R30] THE ONE: PLEASE STOP SHOWING ME ADS IN AN APP I PAY FOR I have tried sooooo many fitness apps, and after 4 years, I think I have found that one that will make a difference. To give some context, I am a 21 year old male that is 140 pounds and I am looking to gain weight by building muscle. After only a month of using this app I am already noticing a difference, and people around me are too. This
- [R32] Spammy Pop-Ups for Paid Users 👎🏻: Really disappointing that as a paid user for SEVERAL years (5 to be exact) I started getting pop-ups every time I open the app. It looks tacky and should not be the experience for users paying $60+ per year for an app.
- [R8] Scammers: It’s a scam. I just subscribed and they talk to $45 and my application doesn’t start when I try to restore the subscription. It says I have no subscription to restore.
- [R15] Total scam: Advertise a free trial then charge you immediately. On top of that it’s a terrible app. Do not download or you will be scammed!!!
- [R17] free bait and switch app: Listed as free to increase their download numbers. Paywalls you as soon as you’re done wasting time building a profile.
- [R3] Pretty Good, Some Improvements Needed: Other people have already said what is great about the app, so here is what needs improvement: - Assisted pull ups and dips, according to the algorithm, get harder with more weight. If you do it successfully at 50 pounds, it bumps you to 55 instead of 45. The opposite should happen… - May not be possible, but should absolutely be useable without Wi-Fi… This
- [R119] Eh: Good exercises however the Pp requires an internet connection and where im aint i dont always have internet
- [R126] Not the best: I don’t like that the workouts will not record to the health app on iPhone even though you have the setting turned on. Simple exercises like Step Ups are not an option. Glute and leg exercises need to be separated and not grouped together. It is supposed to tell you what weight and reps it recommends depending on the last time you did the exercise and it does it sometimes but not alw
- [R328] Not yet a ‘fitness’ app: I’d give this app 3.5 stars if that were an option. It’s not too bad at designing workouts that address an array of muscle groups and that build from week to week. There are some bugs, though. It does not seem to cross-connect exercises very well. If I tell it that I can only do a dumbbell shoulder press at 20 lb each arm, it shouldn’t then propose a barbell shoulder press
- [R10] Stop charging me: Hello - I continued to receive a charge for a $89.99 subscription but I do not have an active account with your company. Please have someone in your customer service department reach out to me.
- [R29] DO NOT EVER GET THIS APP: I pressed the week FREE trial, cancelled it before it ended because I couldn’t understand the app.. a day after my birthday they all all my birthday money $100* out of my account. I made a dispute the following day through apple. They didn’t do nothing. Contacted the app through email they saying they can’t do nothing. lol please do not waste your life on this app. I am a
- [R31] Pricey af: Good. Pricey af.
- [R159] Overall good but Apple watch app not usable: Please give the Apple Watch app some love. It is barely usable even on the newest model.
- [R260] Needs watch app: The idea is you tap when and how many sets you’ve done in a rep. That works great unless you use the rest timer. Having to hold your phone waiting for the next set isn’t great. Then off you go. Which for me means phone back in the pocket. You’ve got to lock your phone or switch apps else it has the habit of tapping on work out your not doing. And if like me you like wired head
