App Templates & Source Codes
If you’re trying to get an app off the ground quickly, starting from a solid template is the most reliable shortcut. This section brings together production-ready projects for iOS and Android, plus cross-platform stacks like Flutter, React, Ionic and game engines such as Unity and Buildbox. Open the project, swap branding and assets, connect your services, and you’re moving.
Templates typically include the full project with source, a quick-start guide, and notes on dependencies and SDK targets. Many are already wired for common needs—authentication, push, analytics, basic storage—and offer optional monetization (AdMob, in-app purchases). You get a working baseline so you can spend time on the features that make your app different.
Browse by platform to narrow the results: Android · iOS · Flutter · React · Unity · Buildbox · Construct 3 · Ionic.
What people usually build here: utility and productivity apps, finance and expense trackers, browsers and media players, delivery and booking flows, social/community features, AI-assisted tools, and a wide range of casual and puzzle games. If you know your audience and monetization plan, a good template gets you to “first usable” fast—and makes iteration less risky.
A few practical checks before you buy: confirm the target/min SDK (and Xcode/Android Studio versions), skim the changelog, make sure the docs cover configuration and builds, and look for notes on services you plan to use (Firebase, OneSignal, REST/GraphQL backends). Finally, choose the license that fits your distribution model.
