별꼴 튜너 vs SheetScope

Oddball Tuner is a chromatic tuner that responds from the very first note. Instead of waiting for the reading to settle, it continuously shows pitch changes with a real-time meter and a time-trail display. As you tighten or loosen a string, you can visually compare the previous and current pitch and bring it to center. Features • Automatic chromatic pitch detection • Tuning modes for guitar, bass, ukulele, violin, and cello • Smooth real-time meter with a 3.2-second pitch trail • Reference pitch setting from A4 = 430–450 Hz • Concert, Bb, Eb, F, and Capo +1 transposition • Adjustable tuning tolerance • Playback of 12 reference tones with selectable octave • Keep screen awake • Dark mode and a choice of free and paid skins • Restore purchases Core tuning features are free. Certain skins are available as individual non-consumable in-app purchases. Microphone input is used only for real-time on-device pitch analysis and is never recorded or stored.

Turn a sheet-music PDF, photo, or scan into an editable digital score. Drop in a MIDI file and get sheet music the other way round. Recognition runs entirely on your iPhone, iPad, or Mac, and results export as MusicXML, MIDI, and PDF. ■ Free · Score recognition — the first page of a PDF, photo, or camera scan, shown on screen to check and edit · MIDI → score — MIDI files exported from a DAW become sheet music, with no bar limit · Editing — select notes, move them up or down, fix accidentals, listen · Add and delete notes, change durations, swap rests and notes, set repeats and 1st/2nd endings by hand · Playback — hear the recognised score right away ■ Pro (one-time lifetime purchase, not a subscription) · Recognise every page of a document · Export — MusicXML (opens in MuseScore, Sibelius, Finale and others), MIDI, PDF ■ What it reads · Lead sheets and single-line melodies with chord symbols · Piano grand staff · SATB choir systems · Drum notation · Key and time signatures, ties, slurs, triplets, chord symbols · Repeat barlines (1st/2nd endings are only partly read — treat them as a guide; missed endings can be entered by hand in the editor. D.C. and coda are not read) ■ About accuracy — please read before buying Measured against scores with known answers (our own tests, September 2026). · Clean printed lead sheets: notes (pitch and duration) 90-99%. Dense sixteenth-note songs around 80% · SATB choir: about 93% · Piano: simple pieces 95%+, complex pieces around 80% — treat as a guide · Drums: hi-hat and snare nearly exact; kick drum misses about half the hits in busy bars — treat as a guide · Ties about 87%, slurs about 60% · Photos: straight, well-lit photos match PDF results; tilted or blurry photos drop sharply · Handwritten and tablature scores are not supported · MIDI → score: quantised MIDI is exact. Piano with up to two voices is accurate; three or more voices and performed (unquantised) MIDI are a guide only Automatic recognition is a first draft. The app is built for checking and correcting in the editor, and it removes most of the time you would spend entering notes by hand. Try your own scores in the free tier before you decide. ■ No internet needed Recognition, editing, and export all happen on your device. Score images are never uploaded. No account, no ads. ■ Copyright Convert only scores you own the rights to, public-domain scores, or scores you have permission to use.
