Capabilities
The essentials for notes, without the clutter.
The focus is not on adding screens for the sake of it, but on making notes fast to create, easy to read and easy to return to.
Fast capture without extra steps
Open, write, return to what you were doing. Notes stay lightweight when you just need to save a thought.
Order through categories and search
Categories, pinning, sorting, trash recovery and search keep your notebook from becoming a pile of loose text.
Rich text for real drafts
Headings, lists, checklists, quotes, code, links and dividers make notes useful beyond a single sentence.
Export and backups under your control
TXT, Markdown, CSV, PDF, Excel and JSON backups are user-initiated when you need to move, archive or inspect your data.

A focused Android notes app
Crystal Notes is built for the small but constant work of everyday thinking: quick ideas, personal lists, drafts, links, reminders, snippets and notes you want to find again later. The app keeps the core workflow simple, so writing and organizing stays faster than managing the tool itself.
Designed for daily capture
- Create short notes, longer drafts, checklists and structured text.
- Group notes with categories and keep important entries pinned.
- Search and sort notes when the notebook grows.
- Recover deleted notes from trash instead of losing them immediately.
- Use light, dark and additional color themes for a more comfortable reading surface.
- 14 interface languages including English, Ukrainian, German, French, Spanish, Japanese, Korean and more.
Rich enough for real notes
Crystal Notes supports headings, lists, quotes, code blocks, links, dividers and checklists. That makes it useful for more than one-line reminders: you can outline an idea, prepare a small plan, collect research notes or keep a reusable checklist.
Your notes stay portable
Export is part of the product, not an afterthought. Crystal Notes can export notes to TXT, Markdown, CSV, PDF and Excel, and it includes JSON backup and restore tools initiated by the user.
Privacy posture
Notes are stored locally on the device by default. There is no cloud sync and no account required. The current release uses Sentry only for crash reporting and diagnostics, with note-related fields scrubbed before diagnostic events are sent. No advertising SDKs, no in-app purchases.
