Everything App is a fully offline, private, and secure workspace designed to manage your thoughts, track your finances, and monitor your health without sending a single byte of data to external servers.

Built with Flutter (Dart 3) and backed by an encrypted SQLCipher database, Everything App combines security, modern aesthetics, and smart features into a single workspace.

✨ Key Features

1. 📝 Rich WYSIWYG Notes

  • Fully Formatted Notes: Write and organize notes using headers, checklists, blockquotes, lists, and images (powered by flutter_quill).
  • Visual Categorization: Associate tags with notes. Note backgrounds dynamically adapt to matching tag color schemes.
  • Auto-Saving & previews: Note content debounces and autosaves. Home cards display clean previews with list checkbox symbols (☐/☑).
  • Grid & List Layouts: Render notes in uniform grid, masonry grid, or simple list view with smooth Material transitions.

2. 💳 Private Financial Manager

  • Dual-Entry Ledger: Track income, expenses, and current balances locally.
  • Smart SMS Auto-Import: Listens for transaction SMS messages (optimized for Sri Lankan bank alerts) and parses transaction types, amounts, and dates in the background.
  • Automatic Reversals & Deduplication: Detects refund messages and auto-reverses logs within 7 days, filtering out duplicate bank application notifications.
  • Graphs & Trends: High-performance line charts depicting monthly income vs expense trends.
  • Inline Calculator: Built-in simple mathematical operator support when entering transaction amounts.

3. 🩸 Health Tracker (Period Log)

  • Privacy-First Cycle Tracking: Offline cycle prediction based on your log history.
  • Prediction Algorithm: Outlier-aware calculations that ignore cycle anomalies (such as < 15 or > 60 days) to prevent skewing future prediction dates.
  • Ovulation Prediction: Computes fertile/ovulation windows using standard luteal phase offset models.
  • Discreet Alerts: Notifies you of upcoming cycles with customizable private text (e.g., "Check the app").

4. 🤖 Offline AI (Gemini Nano)

  • Summarization: Generate bulleted summaries of note content locally. If Tamil text is detected, the summary language adapts automatically.
  • Tag Suggestions: Recommends tags in the note editor based on your existing collection.
  • Selection Refine: Refine selected paragraphs into Casualty, Professional, Expand, or Shorten tones on-device.
  • AI SMS Parsing: Fallback extractor that parses banking SMS formats using native local models.

5. 🔒 High-Grade Security & Encryption

  • SQLCipher Storage: The local SQLite database is fully encrypted at rest using 256-bit AES.
  • Keystore Integration: Encryption keys are randomly generated and secured inside the Android KeyStore or iOS Keychain.
  • Automated Lock: Locks screens immediately or after a custom idle background timeout. Supports Fingerprint, FaceID, or system PIN pattern bypass.

6. 🔄 Media Converter & Utilities

  • Dual-mode conversion: Compress video/images using lightweight native APIs (Lite Mode) or download local FFmpeg binaries (FFmpeg Mode) for advanced formatting and metadata removal.
