Kapsula

Run your own HTML tools on Android. Kapsula runs a self-contained HTML file inside the app. Start with code from an AI chat or a file you made yourself, then use it as a personal timer, checklist or other small tool. No separate app build or developer account is needed for your project. HOW IT WORKS 1. Get one HTML file with its CSS and JavaScript included. 2. Import the file or paste its code into Kapsula. 3. Open your project and use it on your phone. NATIVE FEATURES FOR YOUR CODE Compatible projects can use the kapsula JavaScript bridge for scheduled local notifications, persistent project storage, sound and haptics. These features require code that calls the bridge; importing a browser timer does not automatically add background notifications. A FOCUS TIMER TO TRY The guide at kapsula.app/chatgpt-html-to-phone-app/ includes a reference HTML file and a prompt for adapting it with an AI assistant. Test a 30-second notification, reopen the timer and change the work and break intervals. LOCAL BY DESIGN No Kapsula account or cloud service is required. Self-contained file and pasted-code projects work offline. The app does not collect analytics or track you. WHAT TO EXPECT Kapsula runs your tools inside Kapsula; it does not export standalone apps or run a backend. Projects with external services, packages or frameworks need a separate compatibility check. Notification delivery and sound depend on system permissions and device settings. Your HTML JavaScript is not a background service. KAPSULA PRO The app and its built-in demo are free. Your own projects need Kapsula Pro: a monthly subscription with a 7-day free trial for new subscribers, or a one-time lifetime purchase. Prices are shown in the app before you buy. The subscription renews automatically until you cancel; cancel any time in your app store settings. If Pro ends, nothing is deleted: your projects and their data stay on the device, locked until Pro is active again.

Kapsula provides #app for your UI, console output, await and the existing bridge. Open saved code in the editor and update without losing project data. Copy code errors back to your AI chat. TypeScript, React projects, npm imports and Python are not supported in this version.
