Free HTML to Story Reader app template
A five-chapter story; the next chapter is free after 10 minutes or right away with a rewarded ad.
This is the template running live. Phone features such as the camera, vibration and notifications work in the app you build.
Phone features this template uses
These come from the FreeApp JavaScript bridge that every app built with Free HTML to APK includes. In a normal browser the template still runs, and the calls simply do nothing.
Short native toast.
How the template calls them
// finished a chapter: natural break
FreeApp.ads.showInterstitial();
FreeApp.ads.showRewarded().then(() => openChapter(next));
reading ? FreeApp.ads.hideBanner() : FreeApp.ads.showBanner('bottom');

Build a single-file mobile web app (index.html with inline CSS/JS) for Android WebView.
The app: Story Reader — a reader for a short original story in 5 chapters with a chapter list, progress and adjustable text size, where the page itself decides when ads show: an interstitial when a chapter is finished (before the next opens), a rewarded ad that unlocks the next chapter immediately instead of waiting 10 minutes (timer stored in localStorage), and a banner on the chapter list but never while reading. A five-chapter story; the next chapter is free after 10 minutes or right away with a rewarded ad.
Requirements:
- Mobile-first, touch-friendly UI (min 44px tap targets), works in portrait, supports light and dark mode.
- Use <meta name="viewport" content="width=device-width, initial-scale=1, viewport-fit=cover"> and pad for env(safe-area-inset-*).
- You may load libraries from a CDN (jsDelivr/unpkg); show a friendly message if the device is offline.
The page runs inside an Android app that injects a native bridge as window.FreeApp. Available APIs:
- FreeApp.ads.{loadBanner(unit?, pos?), showBanner(pos?: 'top'|'bottom'), hideBanner(), loadInterstitial(), showInterstitial(), isInterstitialLoaded(), loadRewarded(), isRewardedLoaded(), showRewarded(): Promise<{amount, type}>, on(cb: (e: {event, message?}) => void)} — AdMob; only present when ads are enabled in the builder
- FreeApp.toast(message: string): void — short native toast
Rules for the bridge:
- Always guard calls with `window.FreeApp &&` (or `if (window.FreeApp) { … }`) and provide a browser fallback so the page also works in a normal browser.
- The bridge may be injected after your script runs: do native setup inside `window.addEventListener('freeappready', …)` and also run it immediately if window.FreeApp already exists.
- Do not use alert/confirm for normal feedback; prefer FreeApp.toast when available.
