Primio

Primio is a coding tool that turns a text prompt into a native Flutter app for iOS and Android. Primio is an AI app builder that converts a text prompt into a native Flutter app for iOS and Android, with browser-streamed emulators and submission-ready AAB, IPA and PWA files, aimed at people without mobile development experience.

Primio is a browser-based app builder that turns a written description into a native mobile application. The user types what the app should do, picks a look, and the platform generates Flutter code that compiles to native ARM for iOS and Android, with a web build (PWA) included. The site stresses that the output is not a web wrapper and does not run JavaScript at runtime, which sets it apart from builders that package a website inside a shell. The workflow covers three stages. In the build stage, a live preview shows the app as it takes shape, with auto-fix for errors, rollback to earlier versions, and a curated Design Library (styles such as Neumorphism and Aurora Gradient are shown) meant to keep results from looking machine-made. In the test stage, real iOS and Android emulators stream to the browser, so devices can be switched, logs captured and a live session shared without installing Xcode or Android Studio. In the publish stage, Primio produces a signed AAB for Google Play, an IPA for App Store Connect and a PWA for the web, generated server-side so the user does not handle certificates. A recent addition lets several people work in one project by adding collaborators by email. The audience is mainly people with little or no mobile development experience: founders validating an idea, designers, and small teams that want a store-ready app without setting up a native toolchain. Developers who prefer Flutter may also use it to get a starting point quickly. The site also links to an app store rankings page for discovering apps. Among alternatives, Primio competes with general AI app builders that target the web, and with low-code mobile platforms. Its narrower focus on Flutter and store-ready binaries is the main differentiator. Usage is metered through tokens on a plan, trying it is free without a credit card, and email support is limited to paid plans and to platform issues rather than coding or prompt help.
