Primio
Primio is an AI-powered Flutter app builder that turns a high-level idea into a production-ready mobile app. Describe what you want to build, let the AI generate the Flutter code, and let Primio ship a signed iOS or Android binary through an automated build pipeline.
What is Primio?
Primio is the answer to a simple question: why does it still take a small team and weeks of setup to ship a mobile app? Most of that time goes to scaffolding, build configuration, signing, and submission — work that has nothing to do with the product itself. Primio collapses that work into a pipeline so the team can focus on what the app actually does.
You can build apps with Primio's AI-powered Flutter app builder at primio.dev. The platform is built around Flutter so a single codebase ships to both iOS and Android, and around AI so the Dart code, layouts, and integrations can be generated and iterated from natural-language briefs rather than hand-written from scratch.
How Primio works
Under the hood, Primio orchestrates the full path from a Flutter project to a signed binary that's ready for the App Store or Play Store. The build pipeline handles the parts that are tedious to do by hand:
- Validates a Flutter project and generates the CI configuration needed to build it.
- Provisions an ephemeral build on Codemagic CI/CD and runs the iOS or Android build there.
- Handles App Store Connect signing credentials securely — they're passed in only when needed and never persisted in source control.
- Returns a signed IPA (or APK / AAB) that's ready for upload to the relevant store.
- Cleans up temporary repositories and build artefacts when the run finishes, so nothing lingers.
The result is that a Flutter team — or an AI agent acting on the team's behalf — can iterate from idea to a live test build without setting up CI by hand for every project.
Who built Primio
Primio is operated by Primio Inc. and a team of mobile industry veterans who have spent years developing and publishing apps with millions of downloads.
