Star Coffee App is a React Native Expo application developed by myself as a personal project. The project is still in the development phase, and I am currently working on the UI design. The blockchain integration and backend development will be added later.

• It is our first screen where we have 2 options as Get Start and Login. If we click on Login, we reach the Login Screen.
• After saying Get Started, you are directed to the onboard screen.

• There are 3 screens on the onboard. You reach the last screen by swiping right and you reach the SignUp screen by clicking Start.

• This part is the Register screen. Here we start using our application by saying Join Now.
• You can also perform your registration on both google and facebook.
• Of course, you need to provide google and facebook connections first.

• Here we perform our login process.
• Good Morning is written in the upper left corner, it changes according to the time you are in, Good Night...
• As you can see, if the content is empty, the user receives a warning mode.
• When the user enters the e-mail and password, it exits the hourglass mode and reaches the home page.
• If you forget your password, when you click Forgot Password, it sends you an e-mail to renew your password.
• In the middle, the coffees sold are advertised.

• If you forget your password, your e-mail information will be received on this screen and an e-mail will be sent to renew your password.

• Coffe Screen Bottom is the first screen of the tab bar, you can search for the product you want on this screen, you can select it according to its type, and there is an automatic sliding slider as seen on the screen.
• In the slider, you are directed to that screen according to the type you choose.
• Below are the prices of coffees and other products.
• In this section, you may like the product and maybe you want to buy it later, and you can see the content by clicking on the product.

• You can review the product you choose or click on the heart, and you can buy it according to the size or the quantity you want to buy.

• The second screen of the bottom tab bar, Wallet Screen, this screen keeps your virtual wallet information.
• And your account activities are displayed.
• With this virtual card, you can both buy the coffee you want in the application and make your other payments, this shows that the application is not just a coffee application, it is a much more advanced application.
• When you click on the qr code icon, a qr is created for you and you can shop anywhere you want with this qr.
• You can add more than one card and you can make any purchase you want with these cards.
• You can shop in the same way by clicking the qr scan icon in the upper right corner of the screen.

You can test the application after downloading the "Expo Go" application from the Play Store or App Store and scanning the QR.
