FAQ
What is Rappid Workflow and how does it differ from traditional Flutter development?
Rappid Workflow is our proprietary e-commerce mobile app development model built on Flutter technology. Instead of coding every standard e-commerce feature from scratch, we leverage our proven components and AI. As a result, we shorten development time and reduce costs, delivering apps faster than in the traditional model.
How much does it cost to build an app in this system?
While the final quote depends on your specific project requirements, our internal benchmarks show that the Rappid Workflow model can reduce development time and costs by up to 45% compared to traditional “from-scratch” Flutter programming. It is the ideal solution for small to medium-sized e-commerce businesses looking for a fast market entry, as well as for larger companies wanting to deploy new features rapidly.
What e-commerce platforms does Rappid Workflow integrate with?
Our architecture is flexible. We seamlessly integrate mobile apps with the most popular e-commerce platforms, such as Shopify, PrestaShop, Magento, and WooCommerce. We are experienced in connecting apps with external systems via dedicated APIs.
Will my app visually match my store?
Rappid Workflow provides the ready-made business logic, but the User Interface (UI) is always tailored individually. Our designer ensures that the app reflects 100% of your brand’s visual identity.
How do you use AI in the development process?
AI doesn’t write the entire app for us, but it significantly supports our developers’ work. We use artificial intelligence models to automate repetitive code segments. This AI-powered assistance is one of the key reasons why we can build mobile apps faster.
What are the maintenance costs for such an app?
Maintaining an app built with Rappid Workflow is more cost-effective than using native technologies. Since we leverage cross-platform technology (Flutter), we maintain a single codebase for both iOS and Android. This means that every update or bug fix is deployed faster and requires the work of only one developer.
Can new features be easily added as the store grows?
Yes, full scalability is one of the primary advantages of Flutter and our model. Rappid Workflow provides a solid foundation. As your business grows and you want to introduce custom features (such as chatbots or advanced loyalty programs), our developers will seamlessly integrate them into your existing app.
