Whittle

Whittle: Import. Host. Launch!

One home for every app that matters the most.

Stop keeping a separate app for every small thing you need. Bring one in, or build one — Whittle installs, hosts and launches it right on your phone, fully offline.

A launcher for the apps you make

Already have an HTML file or a zipped web app? Import it — Whittle hosts it locally and launches it in its own sandboxed window: its own icon, its own storage, its own home-screen shortcut.

Don't have one yet? Describe what you want, and Whittle writes a carefully engineered prompt for the AI app you already use. Paste the result back and it imports the same way.

How it works

  1. Bring one in, or describe one

    Import an HTML file or a .zip bundle, or pick a starter idea and let Whittle draft the prompt.

  2. Hand it to your AI

    Whittle shares the prompt to ChatGPT, Claude, Gemini, Perplexity, Copilot or Poe — or copy it anywhere you like.

  3. Bring it back

    Paste the HTML, or use the one-tap deep link to import straight from your clipboard.

  4. It runs

    Whittle hosts it locally and launches it full screen, completely offline.

  5. Fix it

    “Debug with AI” hands the app's own source back to a model for repair, then updates your installed copy.

What you get

Offline by default

Installed apps run from on-device storage — no server, no connection needed.

A real library

Every app you bring in or create, with size and last-opened details, plus a demo app to start from.

Isolated storage

Each app gets its own private data, so they never clobber one another.

Shortcuts

Launch any app with a single tap — from the home screen, and from Siri on iOS.

Reminders

Apps can schedule local notifications that deep-link straight back into them.

Preview

Check an app before committing to install it.

Your work stays on your device

There are no accounts and no cloud sync. The apps you build, their code, and any data they save live only in Whittle's private storage on your phone — we never receive them.

Whittle does collect a small amount of anonymous usage and crash data to keep the app working, and it never includes the content of your apps. The Privacy Policy spells out exactly what that is.
