Cross-Platform App and Website Development

@deepbansal1111

Hello, I have read your requirement to build an Android app, followed by iOS and a website, with in-app purchases as the initial focus. I can do that, and I have 8 years of experience in mobile app designing and development with a backend. I have developed more than 200+ mobile apps with in-app purchase integration, real-time notifications, and secure authentication. I can start by building the Android app with smooth in-app purchase flow and then move to iOS and web. For the website, I will ensure it is responsive and aligns with the app’s UI/UX for consistency. Based on similar projects I’ve done, I can share my portfolio showcasing apps with subscription models, in-app purchases, and cross-platform compatibility. The estimated timeline for the Android app MVP would be around 5–6 weeks, with iOS and the website following afterward. Once I understand your feature list in more detail, I can provide a more precise breakdown. Would you like me to prepare a detailed roadmap with milestones for each phase (Android → iOS → Website)?

Hello there, I can build your Android app first with in-app purchase functionality, then extend it to iOS and a responsive website. The app will include secure user authentication, smooth in-app purchase integration, and real-time notifications if required, ensuring a consistent experience across platforms. I have 11 years of experience in mobile and web development, having delivered apps with payment integration, cross-platform consistency, and scalable backend connectivity. To proceed: 1. Do you have a preferred payment/in-app purchase provider (Google Play Billing, Apple IAP, Stripe for web)? 2. Should the website be a lightweight companion portal or a full-featured platform with the same functionality as the apps? I can share my portfolio and provide a timeline and budget after reviewing these details. Best regards.

Hello Sir , I can help you develop a cross-platform solution—starting with the Android app, followed by iOS and a responsive website. I’ll ensure smooth in-app purchase integration, clean UI/UX, and scalable architecture so future updates and cross-platform extensions are seamless. Do you prefer native development (Kotlin/Swift) or a cross-platform framework (Flutter/React Native) to speed up Android + iOS builds? Should the Android app launch as an MVP with limited features or include all planned features from the start? Are there specific devices/OS versions we must prioritize for compatibility?
