Try Firefly FREE for 7 days ONLY FITNESS APP WITH REAL-TIME FORM FEEDBACK Firefly provides a 7-day workout plan for busy individuals who want to make the most out of their workouts or morning stretches and not have to guess if their form is right. Using only your phone's camera, Firefly builds good workout habits by instantly correcting your form using verbal and visual cues based on your mobility level. No extra hardware, scheduling, or video calls required. With Firefly, you'll gain access to: REAL‑TIME FORM FEEDBACK The only app capable of real-time feedback on every rep, thanks to Firefly’s advanced motion tracker. Your AI coach will correct your form and posture in real time, no matter how many times you mess up. MOBILITY ACCOMODATIONS Freely adjust how strictly the AI coach grades your form. Firefly won’t count your reps or seconds unless you match the coach’s movements correctly as seen on screen. REVIEW & IMPROVE At the end of every workout, Firefly creates a 3D stick-figure replay of your movement for each exercise. Each replay highlights your mistakes and the affected areas of your body. You can also view the number of reps attempted and your average form score for each exercise. No video is recorded or stored. PERSONAL ACCOUNTABILITY To progress in any program, you must complete workouts where every rep is performed with proper depth. Only reps executed with correct depth and posture are counted. (Based on the difficulty that you set) 7‑DAY WORKOUT FRAMEWORK Create a lifelong habit by completing your 7-day program. You're not just getting a weekly workout plan; you're getting 1-on-1 training, which usually costs hundreds of dollars an hour. CUSTOMIZE YOUR ROUTINE Pick from our library of trained poses and movements. Firefly adapts feedback to your form so every stretch and movement drives real progress. WORKOUT PROGRAMS Gamify your workouts by earning badges for hitting milestones from workout programs and completing fitness challenges. SHARE YOUR BEST REP MOMENT Before ending the workout, Firefly shows you the BEST rep you've done. Share with your friends, family, or us! DAILY CHECK INS Get small reminders notifying you to workout each day. Something is better than nothing.

Room to improve
11/24/2023

Serious gamer (doesn’t rage)
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

The gesture demo and detection could be improved

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! To extend this conversation, feel free to shoot us an email: fireflyapp.customer@gmail.com.Thank you!

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! :-)
