AppSources is a platform that offers an array of both free & premium templates designed to help you launch your next iOS mobile app project much quicker. Every template is built with all the latest and greatest first-party technologies from Apple, such as Swift & SwiftUI to ensure the best performance possible, as well as to make the templates future-proof. You will also get both Sketch & Figma design files with each of the templates.

For now, the platform only offers simple free & premium templates designed & built by us and it's in quite an MVP state, but our goal is to let others submit their templates too and sell them on AppSources. The other goal that we have for AppSources is to make the process of looking at various designs on the platform for a specific section of the app (Let's say onboarding or sign up) and then being able to download the design files with just a single click for this specific section or effortlessly copy & paste the source code into your own project.

Here are some of the key features of templates available on AppSources: - Fully coded - Reusable components - Easy customization - Neatly organized Xcode projects - Support for dark mode - Support for dynamic type - Available on iPadOS as well - Sketch & Figma design files included - Global styleguide in Sketch & Figma - UI components library in Sketch & Figma
