Trombone Trainer is a trombone slide position chart and practice game for brass players. Pick an exercise, hit play, and move to the correct slide position as each note sounds — the app scores your trombone slide positions in real time and highlights the note you're on, so you build the link between what you see on the staff, what you hear, and where your slide goes. Built for trombonists: • Arm slide — play it like a real trombone. Hold the phone in front of you and move your arm: the front camera reads how far the phone is from your face, and the on-screen slide follows, position for position. Fit it to your own reach in two taps, then fine-tune any position. It’s optional — touch still works — and nothing is recorded or leaves your device. • Interactive slide position chart — the on-screen chart shows the right slide position for every note (all seven), and real-time scoring gives you credit for holding it as the note plays, with a clean-run detector that rewards mistake-free passes. • 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. • Bass-clef staff — everything is written and read in bass clef, the way trombone music actually looks. • Play-along loops — eight measures on the staff, played back with a piano-style chord under each measure, so you train positions in a musical context, not in silence. • Alternate positions — set your own preferred slide position for notes that can be played in more than one place. • Swipe to control — swipe left/right to change tempo. • Trombone scales and studies — built-in libraries of major and minor scales, chromatics, arpeggios, and technical etudes for daily brass practice. • 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, Korean, Dutch, Polish, Swedish, Norwegian, and Chinese. Free to start: • The free version includes seven major scales, fully scored, so you can practice positions right away. • Upgrade to Standard to unlock every song, import songs and libraries, and share songs; Pro adds creating, deleting, and exporting whole libraries. Standard comes as a yearly subscription with a 7-day free trial or as a one-time purchase; Pro is a one-time purchase. Whether you're a beginner learning where the slide positions are or an advancing brass player pushing tempo, Trombone Trainer keeps your trombone practice focused, musical, and measurable.

Verdict
The clearest difference is in-app purchases: 2D Trombone Slide Positions at none against Trombone Trainer's 3. 2D Trombone Slide Positions also leads on ratings volume (286 vs 1) and iOS requirement (12.0 vs 18.0). Trombone Trainer's advantage is ads (none vs shown) and update cadence (every 5 days vs every 32 months). On price and device support there is nothing between them.
