TIPS ARE :–
Get design look from dribbble.com
Mobile section of dribbble Dribbble - Discover the World’s Top Designers & Creative Professionals
Always firstly work on design in kodular rather than making working app
Use different fonts in your app which you can download from dafont.com
Always prefer more to cardviews rather than other arrangements
Use animations like(Loading on Lottiefiles. Free Lottie Animation)
For example (Set of people using modern technologies | Free Vector)
Prefer more to light mode more than dark mode.
Use different background colour of screen than of arrangements (but use only little different colour than content)
For example :- #F7F7F7 as background and #FFFFFF as cardview background(cardview is content)
Prefer more to ios designs
Use high quality images which you can download from http://www.iconarchive.com/
Use gradient of light colour( don’t use gradients everywhere in your this will make your app very ugly)
I will update this post if I found more.
Please kodular staff add a way to change the elevation color of cardview.
