5/5Love this game. Have a few ideas for future updates.
I have to say this game has made it more interesting for me to organize my workout and more fun because I feel like Sung Jin woo. I do have a few ideas for the future. You could provide a tab that has links to videos for self improvement. It could be a language tutorial or it could be nutritional guide video. If you complete the video you watch that gives you exp. Ik you have daily quests that say to watch a video on it but I thought put a link on that quest could be helpful. I also love the muscle avatar but I’m thinking if we could also create a separate avatar for customization. And you can gain certain customization options when you complete a quest or when you level up. And Ik you have a workout ranks like bodyweight, personal, weights, machine, and overall. But I was thinking maybe you could separate sports rank. For example martial arts ranks and have quest for those along with videos for the training. It doesn’t have to be just martial arts it could also be any other sport the user is into. Oh and instead of having a rank status for just physical you could also have a rank status for any skill they want to learn as well. They can choose what skill to learn and have separate quests tabs for both physical and skills/ intellectual. This is just an idea but I think it would be really cool to implement into this app. But whatever idea you may have that might be different than mine for the future I can’t wait to see, truly love this app and continuously leveling up on it. Thank you.

5/5Awesome App, ranking system is a little buggy
I love this app. The fact it’s being made by one developer is so cool, and being a fan of the Solo Leveling anime makes it a really fun way to track my workouts. The only real problem with it right now is that the ranking system is super buggy, and the fact that this system is so integral to the app as a whole is why I only reviewed it at 3 stars. The numbers automatically get skewed, and I’ve tried inputting my numbers differently but no luck, the numbers keep changing so I can’t compare weight and reps to my new records. If the dev can fix this, it’ll be an automatic 5 stars for me!

5/5Time to LEVEL UP
Lifelong gamer here. The way this app is set up really speaks to who I’ve become along with my favorite hobby: gaming. When you decide you’re ready to take your fitness seriously and want to add fun to the challenge, I would recommend checking out the app. Been in it since the Beta and I really enjoy using it.

3/5Great app, Few bugs
Honestly, great app and great concept. I’ve been using this app since it was in beta and it’s had its fair share of bugs. The only real one(s) that stand out to me right now is the inability to “continue my workout”. When the button outright doesn’t work, i have to restart my entire workout and (try) to remember how much i lifted, which is tedious to do. At that point i might as well just keep using my notes app, since it actually keeps my text The workout history tab just loads infinitely, as well as the general Home Screen. Apart from those complains i really really like this app; just hope that i don’t have to worry about filling out my workouts more than once 😭

Just can't wait for more people to know about the app so the competitive part of the ranking gets better (and hopefully when it does a way to make sure people are doing the workouts to keep it honest and competitive )but other than that highly recommend the app

          "body": "I have to say this game has made it more interesting for me to organize my workout and more fun because I feel like Sung Jin woo. I do have a few ideas for the future. You could provide a tab that has links to videos for self improvement. It could be a language tutorial or it could be nutritional guide video. If you complete the video you watch that gives you exp. Ik you have daily quests that say to watch a video on it but I thought put a link on that quest could be helpful. I also love the muscle avatar but I’m thinking if we could also create a separate avatar for customization. And you can gain certain customization options when you complete a quest or when you level up. And Ik you have a workout ranks like bodyweight, personal, weights, machine, and overall. But I was thinking maybe you could separate sports rank. For example martial arts ranks and have quest for those along with videos for the training. It doesn’t have to be just martial arts it could also be any other sport the user is into. Oh and instead of having a rank status for just physical you could also have a rank status for any skill they want to learn as well. They can choose what skill to learn and have separate quests tabs for both physical and skills/ intellectual. This is just an idea but I think it would be really cool to implement into this app. But whatever idea you may have that might be different than mine for the future I can’t wait to see, truly love this app and continuously leveling up on it. Thank you.",

          "body": "I love this app. The fact it’s being made by one developer is so cool, and being a fan of the Solo Leveling anime makes it a really fun way to track my workouts. The only real problem with it right now is that the ranking system is super buggy, and the fact that this system is so integral to the app as a whole is why I only reviewed it at 3 stars. The numbers automatically get skewed, and I’ve tried inputting my numbers differently but no luck, the numbers keep changing so I can’t compare weight and reps to my new records. If the dev can fix this, it’ll be an automatic 5 stars for me!",

          "body": "Honestly, great app and great concept. I’ve been using this app since it was in beta and it’s had its fair share of bugs. The only real one(s) that stand out to me right now is the inability to “continue my workout”. When the button outright doesn’t work, i have to restart my entire workout and (try) to remember how much i lifted, which is tedious to do. At that point i might as well just keep using my notes app, since it actually keeps my text The workout history tab just loads infinitely, as well as the general Home Screen. Apart from those complains i really really like this app; just hope that i don’t have to worry about filling out my workouts more than once 😭",
