Just a Text Editor is exactly that: a fast, focused text and code editor for your phone or tablet. No ads. No tracking. No cloud accounts. Just you and your files.

Built from scratch as a native Android app — not a web wrapper, not a port. Designed for people who work with text: developers, AI researchers, sysadmins, writers, and anyone tired of notepad apps riddled with banners and upgrade prompts.

Built for real work

• Tabbed multi-file editing — keep several files open and switch quickly
• Recent files drawer with last-edit-location reminders — pick up exactly where you left off, even days later
• Syntax highlighting for 19 languages: Python, JavaScript, JSON, XML, HTML, CSS, Bash, Markdown, TOML, INI/conf, C#, PowerShell, Java, Kotlin, SQL, PHP, C, C++, and Pascal
• Find and replace with plain text or regular expressions
• Persistent undo that survives closing the file — your edit history comes back with you
• Go-to-line and a precision cursor tool for exact small-screen positioning
• Quick-access toolbar above the keyboard — common actions at thumb's reach without leaving the keyboard
• Markdown preview for readable rendering of docs and notes
• Full session restore — reopen the app and everything is exactly where you left it
• Unsaved scratch buffers survive app close and even device reboot — type something quickly without committing it to a file

Handles large files gracefully

Most mobile editors give up on anything bigger than a few megabytes. Just a Text Editor opens files up to 10 MB with everything on — full editing, syntax highlighting, undo, and search. It keeps editing and undo working on much larger files, with syntax highlighting available on demand, and switches to a lightweight read-only mode for the truly huge ones. Whatever's active is clearly flagged so you always know what you're working with.

Reliable with your files

• Crash-safe saves — every write goes through an atomic temp-and-rename, so a power loss or crash mid-save can never corrupt your file
• Detects and preserves file encoding (UTF-8, UTF-16, etc.) and line endings (LF/CRLF) — files round-trip cleanly

Clean by design

• Light and dark theme (follows your system setting, or override)
• JetBrains Mono bundled, plus system monospace and custom font loading
• Pinch-to-zoom, and full respect for your system accessibility font size
• Per-language overrides for word wrap, indentation style, and tab width — with sensible defaults out of the box (4 spaces for Python, 2 for JavaScript, wrap on for Markdown, off for code, and so on)

Private by construction

• No INTERNET permission — the app literally cannot connect to the network
• No analytics, no crash reporting SDKs, no telemetry, no advertising networks
• Your files stay on your device, accessed through Android's Storage Access Framework
• No account, no login, no cloud sync
