King of App

What it is

King of App is an app builder that starts from a website. Its home page, written in Spanish, calls it "El WordPress de las apps" (the WordPress of apps) and "la plataforma abierta para crear apps" (the open platform for creating apps). The pitch is to turn any website or online store into a real app, design it without limits, get at the code and publish on iOS and Android.

The reader it speaks to is twofold. A shop or publisher that already runs on a CMS or e-commerce system can add an app to it. An agency can use the platform as its mobile engine, and a separate Reseller plan exists for that. The home page is in Spanish, with a language selector that also offers English, Catalan, French, German, Portuguese, Japanese, Chinese and Arabic.

What you build and how

The flow on the page has three stages. You connect your content, which can come from a CMS, an e-commerce system or an API, and the page says it syncs live. You build in King of App, with design, plugins and code. Then you publish to iOS and Android. The connection list on the page names WordPress, WooCommerce, Shopify, VTEX, PrestaShop, Magento, Drupal, Joomla, Wix, Webflow, BigCommerce, Google Sheets and Blogger. There is no built-in database to design; the content you manage stays in the system you already use, and King of App organizes pages, menus, modules and data from one panel.

The editor is visual and drag and drop. The page's line for it is "Diseña experiencias móviles reales sin escribir una sola línea" (design real mobile experiences without writing a single line). It describes modular editing, a live preview of the app in real time and iOS and Android output, and it says you can enter the code when a project needs it. Design is not meant to be template-bound: the page contrasts a "standard app builder" with fixed layouts and limited customization against King of App's "100% flexible design". It lists custom interfaces, complex menus, advanced navigation, transitions and animations. The platform advertises 50+ native menus.

Features come through plugins. The page says 400+ plugins are available and that you can switch on payments, maps, analytics, push, AI or e-commerce, with Stripe, Firebase, maps, WooCommerce and Shopify shown in the plugin strip. Push notifications and engagement are a named capability: sending push, running campaigns, tracking metrics and using AI assistants to segment and re-engage users.

Code access is the part of the pitch King of App leans on hardest. The site says the code is "abierto y descargable" (open and downloadable) and puts it as "Descarga, modifica y despliega sin depender de nosotros" (download, modify and deploy without depending on us). It also states "100% acceso al código" and "Código 100% tuyo". The closing banner sums the platform up as "Una plataforma. Código abierto." (one platform, open source), and the page shows an app.config.js file importing the kingofapp package as the example of code you hold. The navigation lists separate license pages for paid modules and for free modules, plus terms and a returns policy, and the support menu invites developers to publish a module of their own.

Publishing is described as automatic and guided. You compile once and generate builds for iOS and Android, ready for the App Store and Google Play, and the page shows a build moving through to both stores.

AI shows up in two ways. The first is the MCP link: you tell your preferred AI assistant what app you want, connect King of App's MCP, and the page says services, content, menus, modules, automations and publishing end up structured in your panel. The second is an AI agent panel that the page describes as coordinating strategy, tasks and opportunities across growth, revenue, positioning and engagement.

For agencies, the page says to stop selling hours and sell apps. The Reseller plan is described as multi-project management, apps powered by King of App and expert training and support, so an agency can run several client apps side by side.

The resources menu shows what the first weeks look like: an app builder guide, a plugin directory, example apps, a getting started guide, a guide to importing an external app, tutorials, a guide to creating screenshots for the Apple App Store and Google Play, and a guide to creating a single download link for an app. An Academia section sits beside them.

Plans, reviews and support

The home page publishes no prices and no plan limits. Its calls to action say "Sin tarjeta" (no card), "Sin permanencia" (no lock-in) and "Empieza gratis" (start free), and the navigation points to a Precios (pricing) page and a Plan Reseller, but the home page itself states no figures for either.

The claims about scale are the company's own. It says 40K+ apps created, 400+ plugins, 50+ native menus and 100% code access, plus "10 años construyendo apps" (10 years building apps). The "grandes marcas" section carries no readable customer names. The page lists recognition from the Horizon 2020 European program, VTEX Connect as a LATAM partner ecosystem, GoodFirms, EIC Brussels, Top 100 Startups in Spain, South Summit, OpenExpo Europe a finalist spot at Web Summit in Dublin and a finalist spot at Startup Mansion in New York.

Reviews are shown as a 4.5 rating from 16 Google reviews. Dated quotes include a 2021 review that says it is excellent to have a no-code platform that turns WordPress or any other CMS site into an app, a 2021 review calling it an excellent application that lets a business offer a more complete service, and a 2020 note praising the support team as always available and very kind. An agency review says King of App let it widen its offer and deliver apps to clients already working with CMS and e-commerce systems. The support section lists options to buy or open a support ticket, technical documentation, tutorials, GitHub and a path to publish your own module, and the closing call to action offers a conversation with an expert.

Who it suits

It suits an agency or freelancer with clients on WordPress, WooCommerce, Shopify, VTEX or similar systems, who wants to sell apps without hiring native developers and who likes having the code in hand. It also suits an e-commerce or content team that wants native iOS and Android apps fed by the catalog or posts it already maintains.

The caveats are practical. Budgeting means opening the Precios page or talking to the company, since the home page carries no figures. The home page is written in Spanish, which a team buying in English should know. Because the code is downloadable, owning it also means owning what happens after you change it, and a solo founder with one simple MVP may prefer a tool that hides more of that. A reader who wants a one-minute website wrapper will find this heavier than that, because it is a full builder with plugins, a content connection and a store publishing flow.
