I think that this application had many good factors with a few minor inconveniences. First, the app is a phenomenal idea, with artificial intelligence (A.I.) tracking your specific movements to perfect your form in workouts. This app is great for beginners, just starting to workout and targets specific area muscle groups. This app is truly innovative with their collection of workouts ranging from easy to hard. One small critique i have is to add some more workouts, and longer, harder workouts. Sets are about the right length, and workouts are fairly intense. I would like to see some more focus on legs, and make some more workouts in general. The design needs some work but. The AI works well to make sure your posture is perfect, though it can be tricked somewhat easily into giving reps. Overall, this app is great, at what it needs to do, the Ai just needs some tweaks, and the general verity can be improved. 3.5-4 stars
Amazing app

The gesture demo and detection could be improved
Erlang_Shen
Thanks the developers for this app. It makes me feel being accompanied and instructed when doing exercises at home. First, we want good looking coaches, both in face and body, use AI to create some please. Second, the gesture detection is too harsh. For example, I cannot keep my legs straight up immobile when doing toe touch. Can we have the choice to set the difficulty level, like easy, normal, strict?I will come back with a 5 star if the improvements hit me soon.
Developer Response
We're really happy to hear that! Yes, we want to film with trainers for the videos to make it look nicer! For now, we want to provide proper demonstrations, but it's a bit difficult for AI to capture the micro movements properly. At least with our current skillset.I'm glad you mentioned it! Yes, you can tap the screen during your workout and then click the orange gear icon. From there, you can adjust how strictly the AI coach grades you. (Feel free to view the tutorial for a better visual explanation. Profile tab -> App Demo Video).We understand that everyone has different levels of mobility for different exercises so please set it to what you feel comfortable. :-) As always please be safe when exercising and hope you see results in the coming month!

Frustrating
Snacks86
The AI camera function is not that accurate. I have to do 100 squats, lunges, or whatever else to get 15 good reps. It took 45 min because apparently I wasn’t doing the lunges correctly. Even when I adjust the coach setting it’s difficult to get through a workout. Extremely annoying and frustrating.
Developer Response
*Update: We released an update that increases your volume at the start of the workout so you know about the verbal feedback feature in the beginning. Hope this helps!Hi Snacks86! Thank you for this honest review. 100 reps and 45 minutes is a LOT of effort, and we really appreciate your insane effort. We'll do better on our part to make the instant verbal feedback feature clearer so you don't have to realize the mistakes after so many attempts.Having to constantly adjust the coach setting mid workout has to be very annoying. While we do want to accommodate different mobility levels to help everyone, it shouldn't be that frequent. Please feel free to send us more of these so we can continue to learn and make the app better for everyone. (fireflyapp.customer@gmail.com). As we continue to adapt, we hope to provide you with a much better experience next time. Thank you! :-)
