Speed Read uses RSVP (Rapid Serial Visual Presentation) to help you read faster. Words are displayed one at a time with a highlighted focal letter, training your eyes to stay centered and eliminating subvocalization — the habit that slows most readers down. Import your own books, articles, and documents in EPUB, PDF, TXT, or Markdown format. Paste any web URL and the app extracts the article text automatically. Your entire library lives on-device. Features: - RSVP reader with a color-highlighted focal letter for each word - Adjustable speed from 50 to 1,000 words per minute - Two play modes: Play/Pause or Press to Play (hold to read, release to stop) - Chapter navigation for multi-chapter EPUBs - Import documents: EPUB, PDF, TXT, and Markdown files - Read web articles by pasting a URL - 7 monospace font choices including JetBrains Mono, Fira Code, and Courier Prime - Adjustable font size - Reading position saved automatically — pick up where you left off - Pure black dark theme designed for OLED screens - No account required. All data stays on your device.

Memz is your second brain — a private memory vault that lives entirely on your device. Capture anything in one tap: speak a thought and let on-device voice-to-text transcribe it, jot a note, save a photo, a screenshot, or a file. Memz reads and organizes it all into an evolving map of your memories — clusters that grow and reshape as you add more, with no manual filing. Then just ask. Memz recalls what you saved with answers grounded in your own sources, and shows the evidence behind every reply. When it doesn't actually have the answer, it tells you — instead of making something up. PRIVATE BY DESIGN - Everything stays on your phone. No account, no sign-up, works fully offline. - On-device processing — your memories are never required to leave your device. - Sensitive memories (Care and Secret) are locked behind an unlock step and kept out of everyday search. YOU OWN YOUR DATA - Export anytime to Obsidian-compatible Markdown. - Delete derived data only, or wipe everything — your call. WHAT YOU CAN CAPTURE - Voice notes with on-device transcription - Text notes and quick thoughts - Photos and screenshots, with on-device text recognition - Files and documents HOW MEMZ ORGANIZES - An evolving ontology groups related memories automatically - Review, merge, or split clusters as your thinking changes - A visual map shows how everything connects ASK YOUR MEMORY - Source-grounded recall with evidence for every answer - Scope your question; private categories stay excluded by default - No evidence, no guess — Memz refuses rather than inventing No subscriptions required. No data harvesting. Just your memory — organized, private, and yours.
