Notalune

Notalune shows the name of every note, right on your own sheet music. Point your iPhone or iPad at printed sheet music and Notalune overlays the note names directly above the notes: English (C D E F G A B), German and Czech (C D E F G A H), solfège (do re mi) or Japanese katakana (ド レ ミ). No typing, no searching, no flipping through theory books. BUILT ON TRUST Notalune follows one rule: blank beats wrong. If it is not sure about a note, it leaves it unnamed instead of guessing. One tap on the traffic light shows how confident every name is (green, orange, red). Every scan starts with a quick clef check, and any name can be corrected in two taps. WHAT YOU CAN DO • Quick reading: point at one measure or a whole page and get the names in seconds. Nothing to create first; keep the reading or let it go • Any measure opens in place, with practice, editing, re-reading and sharing tools around it • Pieces: build your own library, piece by piece, measure by measure • Whole pages: photograph a full page or import a scan, map its measures, and read them one tap at a time • PDF import: title, composer and tempo fill in from the file, and every measure reads itself in while you watch • Open in Notalune: send a PDF from Mail, Files or WhatsApp straight into the app • Octave numbers, if you want them: c¹ c² in the Central European style, C4 C5 elsewhere • Annotated page: the assembled page with every name in place; practice from it with pinch-zoom and free pan • Print and share: export the annotated page or the whole piece as a PDF (Pro) • Metronome: a real mechanical metronome with tap tempo, free and unlimited • Corrections: fix any name, change the clef or key, or revert; uncertain notes are easy to spot FOR REAL SHEET MUSIC From method books and first songbooks up to harder repertoire. Recognition works best on printed music photographed up close, one measure at a time. In My Sheet Music you can assemble and read whole pages, measure by measure. A SCAFFOLD, NOT A CRUTCH The names are made to be hidden. In practice mode, tap a single name to hide just that note and test yourself. Tap again to reveal it, or bring them all back at once. The goal is the day you read without Notalune. PRIVATE BY DESIGN Everything happens on your device. Photos are processed on-device and stored only in the app. No accounts, no ads, no analytics, no tracking. The app never connects to the internet. If you opt in to help improve recognition, correction snippets are stored locally on your device; you decide if and when to share them, manually. FREE AND PRO Free: 10 quick readings in total, 3 pieces with one page each, the full metronome, practice mode, and every reading and correction tool. The 10 readings are a one-off allowance, not a daily quota - nothing resets, and nothing expires. Pro: Notalune Pro is a one-time purchase - no subscription, no trial to expire - that removes the limits and adds printing & sharing of annotated PDFs. Family Sharing included. IPHONE AND IPAD One purchase covers both. On iPad the reading page shows at close to print size, so you can play straight from the stand. LANGUAGES Seven: English, Czech, German, Spanish, French, Italian and Japanese. Note naming in English (B), German and Czech (H), solfège, or Japanese katakana. The naming follows your choice, not your phone's language: a fixed-do player keeps do re mi on an English phone. Notalune reads notes so you can play them.

Verdict
The clearest difference is ads: Notalune at none against Metronome's shown. Notalune also leads on update cadence (every 10 days vs every 8 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
