French Horn Trainer

French Horn Trainer makes fingering practice a game — and it fits the horn you actually play. Choose single F horn, single Bb horn, or double horn, and the on-screen fingering guide and real-time scoring change to match your instrument.

Pick an exercise, hit play, and hold the correct rotors as each note sounds — the app scores you in real time and highlights the note you're on, so you build the link between what you see, what you hear, and what your hands do.

Built for horn players:
• Three horns, one app — single F, single Bb, and double horn. On the double horn, use the thumb trigger (Bb side) exactly as you do on your instrument; on a single horn, drill the valves alone. Switch anytime in Settings and everything re-fingers instantly.
• Transcribe by ear — play a passage on your instrument and the app writes it onto the staff, note by note, in your key, so you can build or fix a song without tapping each one.
• Real-time scoring — get credit for holding the right combination as each note plays, with a clean-run detector that rewards mistake-free passes.
• Play-along loops — eight measures on the staff, played back with a piano-style chord under each measure, so you train fingerings in a musical context, not in silence.
• Alternate fingerings per horn — set your own preferred fingerings, stored separately for each of the three horns.
• Swipe to control — swipe left/right to change tempo, up/down to transpose to any key.
• Built-in libraries — major and minor scales, chromatics, arpeggios, technical studies, and more.
• Track your progress — daily/weekly/monthly trends, streaks, and unlockable badges, plus a full stats screen for every song with an accuracy-over-time chart. Your best score, average, and attempt count show right in the song list.

Read music your way:
• Note names in letters (C D E), German (H / B), or fixed-do solfège (Do Re Mi) — switch independently of the app language.
• Available in English, Spanish, French, German, Portuguese, Italian, Japanese, and Korean.

Free to start:
• The free version includes scale libraries to practice fingerings right away.
• Upgrade to Standard to unlock every song, import songs and libraries, and share songs; Pro adds creating, deleting, and exporting whole libraries. Both are one-time purchases — no subscription.

Whether you're moving up from a single to a double horn, or drilling scales for your next chair audition, French Horn Trainer keeps the reps focused, musical, and measurable.
