About this app

Pico PDF Viewer is a very lightweight, local document viewer built around
fast switching: authorize one folder, and jump between the PDFs and Markdown
files inside it without picking a new file every time.

■ PDF reading
・Continuous scroll or single-page mode, pinch to zoom and pan for detail
・Full-text search (on supported devices) — jump straight to a hit, highlighted
・Bottom thumbnail strip to jump around long documents quickly
・Immersive controls — tap anywhere to show or hide them

■ Markdown viewing and editing
・Fully styled preview: headings, lists, quotes, code blocks, tables
・Edit in place and save — "Save" overwrites the original file directly,
no switching to another app
・Formatting toolbar (headings, bold, italic, lists, code, tables, links)
and a line-number gutter

■ Quick switching
A side drawer lists every PDF/MD in the current folder — tap one to switch,
no need to go back to the list first.

■ Three themes, three languages
Dark, light, and warm themes switch instantly, or follow your system's dark
mode setting; the interface is available in 繁體中文, English, and 日本語 at
any time.

■ Fully offline
Every file is read, rendered, and edited entirely on your device. There is no
server and no account, and nothing is ever uploaded. The only network activity
is the bottom Google AdMob banner (no interstitial ads) — see the privacy
policy for details.

You can also open a single file directly from another app's "Open with" or
share menu (email, a download notification, …) without authorizing a whole
folder.

What’s new

・Leaving or switching files while editing Markdown now asks before discarding unsaved changes
・New "Follow system" theme that tracks your system dark mode setting
・A four-step intro on first launch (skippable)
・Memory use is now capped for large PDFs, so scrolling long documents stays steady
・Links in Markdown documents are tappable and open in your browser
