CuaderNote vs Scale Ètude

Take notes, highlight your PDFs, and review with spaced repetition flashcards. New: study the day's cards on Apple Watch, with your iPhone nearby or not. Spelling dictations read each card aloud and correct you letter by letter. Built for iPhone, iPad, and Mac. CuaderNote brings notes, handwritten notebooks, reading, annotation, and flashcards into one native workflow. Capture an idea, connect it to what you are reading, turn it into a card, and review it without moving your study material between apps. WRITE Create focused notes with a block-based editor designed for learning. Structure ideas, connect related notes, and turn what you write into flashcards using simple inline syntax. DRAW Think visually in a notebook. Handwrite with Apple Pencil on iPad, sketch diagrams, add shapes, and keep visual notes beside the rest of your library. READ Import PDFs and EPUBs or save web articles. Highlight in four colors, annotate, draw directly on PDFs, and keep a companion note beside your reading. Select a word to look it up in the dictionary, and read books and articles in White, Sepia or Night, or let the theme follow light and dark mode. If you delete a highlight or a sticky note by mistake, Undo brings it back. REMEMBER Review everything in one place with FSRS spaced repetition. Create question-and-answer, cloze, image occlusion, and set-based cards. When answers belong together, one cloze card can hide them all. Each session starts with the cards that are due and adds up to 20 new ones a day, an optional daily reminder tells you when cards are waiting, and Undo takes back a rating you gave by mistake. To practice spelling, turn on Dictation in a note: CuaderNote reads each card aloud, you type the answer, and you see the correction letter by letter. On Apple Watch, you can see how many cards are due and review them from your wrist. AI STUDY TOOLS When you choose to use them, AI tools can suggest flashcards, summarize or explain selected text, translate passages beside the page, generate LaTeX, and extract text from images. An optional account is required only for these tools. CuaderNote is built natively for iPhone, iPad, and Mac, with a companion app for Apple Watch. Your study library is local-first and can stay in sync across your devices with iCloud. Write. Draw. Read. Remember.

Scale Etude helps you truly learn your scales — not just memorize shapes, but hear them, spell them, and own them in every key. It's built for any instrument: everything is by ear and by note name, so it works whether you play guitar, piano, sax, or anything else. TWO FOCUSED DRILLS • Identify by ear — hear a scale played and name which one it is. Train your ear to recognize the sound and color of each mode. • Build the scale — given a scale and key, tap every note that belongs. Learn the correct spelling of any scale in any of the 12 keys. Everything uses strict music-theory spelling, so you learn scales the right way — A Phrygian is A, Bb, C, D, E, F, G (never A#), with each degree getting its proper letter name. EXPLORE AND UNDERSTAND • A browsable library of 11 scales — the 7 modes (Ionian through Locrian), major and minor pentatonic, and major and minor blues. • A detail view for every scale with an interactive interval wheel, a note-by-note breakdown, step formulas, and the character of each scale. • Hear any scale or single note played on a clean, sampled instrument. PRACTICE YOUR WAY • Focus on exactly what you want — a whole family, a handful of scales, or a single scale drilled across all 12 keys. • Turn on Race the Clock to answer against a timer and build fluency under pressure. • Adaptive mastery tracking surfaces your weakest scales first, so every session targets what you actually need. PRIVATE AND OFFLINE • No account, no sign-up, no ads. • Works fully offline and keeps all your progress on your device. Whether you're a student nailing your modes, a guitarist breaking out of the pentatonic box, or a jazz player internalizing every key, Scale Etude makes scale practice focused, fast, and genuinely effective.
