In my experience mobile app designing process go through many steps like,
1) Goal Defining
- What is the purpose of mobile app whether its selling product or selling service, Who will going to use it, what is their demographical status, age group this are thing considered when you defining goal. Should have clear idea of your app. Then after you will be able to create unique & extraordinary user & cost friendly mobile app.
2)Wireframe & Prototype
-This the second most important step where you draw the visual of your UI to get an idea about what going to look like does it need any improvement. What are the menu , button, pages how it will looks like.
3)Typography
-The first impression is the last impression same rule apply here If your font types doest match with your UI then user will not stay on your website for long period they came on your site and closed it and move to other website. Typography play an vital role in app designing.
4) Testing
- The last stage of app designing process is testing the app design how it looks? Does it works proper? Does it user friendly?
This are the measure are taken into account when designing a mobile app.
