There are a lot of things you can do to make your mobile app design look and feel better, but some of the most obvious tips are to keep the tone light and easy to use and to focus on making sure the user interface is easy to understand.

Make sure all your text is readable at a small size, and avoid making your app too cluttered or crowded. Keep buttons large and easily identifiable, and make sure all important information is prominently displayed. Try to use typography that's both simple and legible, and keep your colors muted so they won't distract from the content.

Finally, make sure your app is responsive so it looks good on all devices - from phones to tablets to laptops.
