Whittle vs Folio

Stop keeping a separate app for every small thing you need. Whittle is one home for every app that matters the most — bring one in, or build one — and it installs, hosts, and launches it right on your phone, fully offline. 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, if you're creating one. 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 with no server and no connection. • 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, including from Siri. • Reminders — apps can schedule notifications that deep-link straight back into them. • Preview — check an app before committing to install. Whittle does not run the AI itself. It works with the AI apps you already have installed, so nothing you write is sent anywhere by Whittle.

Folio keeps HTML files readable, interactive, and available offline—exactly the way they were made. No developer-operated server. No Folio account. No conversion that breaks the layout. Bring in a single HTML file or a folder-based page with its referenced CSS, JavaScript, images, and data. Folio gives each page its own local origin so modern pages—including ES modules, fetch requests, and local storage—can work the way they should. BUILD YOUR LIBRARY • Import files from Files or another app's Share sheet • Import a folder-based page with its referenced supporting files • Watch a folder for new and updated pages • Optionally add and refresh selected files from Google Drive • Organize with favorites, tags, searchable icons, sorting, grouping, and library search • Update many pages at once with bulk actions READ AND USE YOUR PAGES • Stay offline by default, with network access controlled separately for each page • Navigate page history, find text, reload, inspect source, and see useful diagnostics • Choose a top or bottom toolbar that gets out of the way as you read • Download files generated by a page, print, or save and share a PDF • Use a full three-column workspace on iPad or focus on the page full screen • Open chosen pages from widgets, and favorites or recent pages from Home Screen quick actions PRIVATE BY DESIGN • No Folio account, advertising, analytics, or tracking • Optional iCloud sync uses your private iCloud database • Optional Google Drive access is limited to files you choose for Folio • Lock individual pages with Face ID or your device passcode • Locked pages are shielded in the app switcher and badged in widgets and quick actions Two included interactive samples make it easy to explore Folio immediately. Keep reports, dashboards, exported notes, archived documentation, and other web files useful wherever you go—even when the network doesn't.
