First Time Doing Mobile app UI

So it's my first time doing game UI for a Fitness Idle game idea that I have. People in other subs have said that it's shit and I have tried to make it better. Whats wrong with it? What can I do to make it better? Color? If you want to interact with it I have a figma link on https://flexion.blog/.
