## What is dHP?

dev HTML Playground (dHP) runs HTML written by ChatGPT or any AI on your iPhone: free, no ads, and no coding knowledge needed. No computer required. Copy
  the AI's reply, paste it, and it becomes your own app. Its data stays on your phone, and it opens from your Home Screen like a regular app.

  IF YOU'RE LOOKING FOR
  - A way to run HTML that ChatGPT made, on an iPhone, for free, with no ads and no programming knowledge
  - A place to keep the budget tracker or diary an AI built for you, with its data, and use it every day
  - A way to build your own tools without owning a computer 
  - A quick way to view HTML documents an AI wrote for you
  
  FEATURES
  
  Code Editor
  A syntax-highlighted editor for HTML, CSS and JavaScript with autosave and file management (add, rename, delete). Smart quotes and other typing
  "corrections" that break code are disabled.
  
  Instant Preview
  Run your code with one tap. console.log output and errors appear in a built-in console, so you can debug entirely on your phone.
  
  AI Integration
  A ready-made environment prompt for AIs like ChatGPT and Claude. Paste it, and the AI asks "What would you like to build?" — just answer in plain words.
  Bring the returned code in with one tap using "Paste & Replace All". You can finish real apps with zero programming experience.
  
  Safe Data Storage
  Every project ships with storage.js, a simple persistence library. Your apps' data is stored safely and kept separate per project. It also works in
  regular browsers, so your creations are portable.
  
  7 Templates
  - Game (Crowd Rush): the real version of that "grow your crowd" ad game
  - Game (Pull the Pin): the real version of that pull-the-pin puzzle from the ads
  - Empty Project: start from a clean slate
  - Basic Sample: learn the ropes with a counter and notes
  - To-Do List: a practical task app
  - Habit Calendar: a monthly habit tracker
  - Game (NEON RUSH): a full neon mini-game demo
  
  Add to Home Screen
  Register your apps as Home Screen icons via Shortcuts and launch them like regular apps.
  
  Export
  Export as ZIP (for backup) or a single HTML file (for sharing). Send your work via AirDrop, save to Files, or continue editing on a Mac.
  
  Opening a saved .html file is just as easy: share it from the Files app and choose dHP. HTML that an AI exported "as a file", or that you received via
  AirDrop, becomes one of your apps. 
  
  HTML Viewer
  Copy any HTML (like a document an AI wrote) and view it with one tap. Everything you view is kept in a history, and you can import it as a project to
  edit.
  
  Built-in Browser
  A browser tab for research or chatting with AI sites, so the whole loop stays in one app.
  
  About your AI
  Works with any AI you like — ChatGPT, Gemini, Claude and more. Free AIs are fine; smarter ones just nail it on the first try more often. And if something
  breaks, dHP catches the error for you — copy it, paste it back to your AI, and it gets fixed.
  
  The interface is available in English, Japanese and Simplified Chinese.
  
  Everything is free, with no ads. Your "I want to build something" — right in your pocket.

### 5/5 — とても使いやすい

*2026-10-27*

AIで作成したhtmlファイルを基に慣用句・ことわざアプリとして使っています。アプリを再起動しても正答率などの記録が保持され、大変助かりました。本アプリ自体、直感的で操作しやすく、初心者でも簡単に使えました。アプリ内に広告もなく、息子に安心して使わせることができます。よって星満点です！

### 5/5 — めちゃ助かってます

*2026-10-10*

コーディング素人ですがGPTなどを使って自分用ツールを作っていて、どうにかしてiPhoneの中でアプリ化できないか考えている最中にこのアプリに出会いました。
自分のやりたいことがほぼそのままできて、めちゃくちゃ嬉しいです！
広告などもなく、シンプルに使えるのでとても助かっています。
今後タイトル編集機能（現状GPTから共有の形で取り込むとデータ内のタイトルではなくフォルダタイトルが採用されるっぽい？）やDo&Undo機能などが実装されるともっと使いやすくなるな、など期待に胸を膨らませながら楽しみにしています。

**Developer response:** レビューありがとうございます！「GPTで自分用ツールを作って、iPhoneの中でアプリにしたい」という使い方は、まさにdHPで一番叶えたかったことなので、とても嬉しいです。

ご指摘のとおり、共有で取り込むと、HTMLの中のタイトルではなくファイル名が名前になってしまいます。また、今はマイアプリの名前をあとから変えることもできません。どちらも次の機能追加のアップデートで、タイトルを優先して取り込むことと、名前を変えられるようにすることに対応する予定です。

元に戻す・やり直す機能も、同じアップデートで対応する予定です。具体的なご要望、本当に助かりましす。これからもよろしくお願いします！

### 5/5 — iPhoneでAIコーディング

*2026-09-23*

お世話になっています。
携帯でローカルなアプリ製作が簡単に実行出来ます。
欲しいと思ったものをすぐ作れる様になる環境がとても良いです。
日本製なので安心して使っていけます。

**Developer response:** レビューありがとうございます！「欲しいと思ったものをすぐ作れる」と感じていただけて、とても嬉しいです。

広告なし・端末の中だけで動くシンプルさは、これからも大事にしていきます。作ってみたいアプリのアイデアや、使いにくいところがあれば、いつでもサポートページからお知らせください。これからもよろしくお願いします！
