Hi! I have to develop a software solution for a youth church group, for my graduation project. In the first meeting that I have with the coordinators, they did not have a clear idea of what they want. The biggest problem they have is the attendance control, they do it manually and that causes errors.
I was thinking of developing an Android app in Android Studio because that is the tool I master, but a friend told me that I consider using a tool that builds for iOS, Android and web. I have like 6 months. I own a MacBookAir but I do not know Swift (for iOS). I am familiar with MySQL, PHP, Apache, JSP,HTML,CSS.
Summary: What tool can I use that is easy to learn and easy to scale?
I think you should chose between Flutter and Ionic. With those two options, the main question is about graphs and performance. Are they really important for your application? If the answer is yes, your tool is Flutter but, if the answer is that you need an easy tool to create an app with some basic components I would choose Ionic. You have a library with lots of components that you can use and they have native UI by default (for Android and iOS).
You will find more support if you use Ionic with Angular as frontend framework (you have the option to use Vue or React but this is a new feature for Ionic and I think there are more difficult to learn than Angular).
You can develop and debug the majority of features on PC (I don't know if that is possible with Flutter). And when you will finish the app, create iOS and Android versions is simple.
It's probably not relevant anymore, but I think Ionic with Angular as the frontend is the right choice. For IDE I would choose Visual Studio Code. You can just create a basic web application with responsive design, which is already included if you are going to use Ionic components with Material Design to create your app. You don't need to know Swift, you don't even have to create mobile apps, just create a responsive (Ionic already is) web app, or PWA. Upon browsing your website from a mobile device for example using google chrome, you will be prompted to create a shortcut of the website in your mobile phone. After you do this, there will be an icon in your phone that looks like an icon to launch an app, it will launch your website in full screen mode - for the user's perspective it will look like he is using a native app. Access https://ionicframework.com/docs/angular/pwa from your android chrome browser, go to tab options (3 vertical dots), click on Add to Home screen. When you launch the website from the shortcut, you'll see that it behaves and looks like a native app.
