aiMetronome — pro-level metronome features in a one-time purchase, no subscription. Built by a musician, for musicians. New in V2: program whole pieces with Tunes, import MusicXML & MIDI, share with students, jump to any bar, loop sections, and set smooth rit. / accel. ramps. --- TUNES --- A tune is a saved sequence of blocks. Each block has its own time signature, tempo, subdivisions, length in bars, optional rit. / accel. ramp into the next block, optional cesura (silent gap) at its end, and a "count-in" flag for the first block. Rehearse with a click that follows your tempo and meter. --- IMPORT MIDI & MUSICXML --- Drop a MIDI or MusicXML file from any notation app (Sibelius, MuseScore, Dorico, Logic). aiMetronome reads tempo markings, time-signature changes, repeats, voltas, cesuras and fermatas — and builds the tune for you. No more re-typing a 100-bar piece bar by bar. --- SHARE & BACK UP --- Send a single tune (.aitune) or your whole library (.aitunes) via AirDrop, Files, iCloud Drive — any iOS share destination. Great for teachers handing students rehearsal plans, or personal backup. --- PLAYBACK LOOP & JUMP TO ANY BAR --- Long-press a block to set loop start / end — the selected range loops indefinitely until cleared. Or drag the red playhead dot on the main-screen banner to jump to any bar instantly. --- TEMPO --- Accurate from 10 to 300 BPM. Twist the big knob for fast moves. Use the +/– buttons for 1 BPM precision. Tap the centre to set tempo by feel — your taps are averaged, so the BPM settles smoothly instead of bouncing on every tap. New in V2: standalone ritardando or accelerando ramps over any number of beats or measures, from any tempo to any target. --- aiVolume™ --- aiVolume™ listens and adapts the click volume to your dynamic range. • Loud playing: click turns up. • Quiet playing: click backs off. • Volume Boost (10 / 20 s) gives a clearer click for count-ins, then fades back to aiVolume™. The click sits naturally in the background of your music — and disappears in the quiet moments where it would otherwise stand out. • Lessons — backs off during discussion, comes up when you play. • Recording sessions — click goes quiet during exposed passages, less bleed into the mic. • Live performance — rises with stage volume, drops in quiet moments where the audience could otherwise hear it leaking from in-ears. --- TIME SIGNATURES & CLICK SOUNDS --- Set any time signature with the new notation-style picker — numerator over a fraction line, denominator below, just like engraved music. Subdivisions in a simple wheel. Pick a click timbre — Claves, Click, or Beep — or mix them. New in V2: choose any timbre to play at half velocity on non-accented beats — a fuller texture that still tracks the downbeat. --- VISUAL & PRACTICAL --- • On-screen flash, device torch, or both. • Layout adapts cleanly: iPhone SE through Pro Max, every iPad (Split View / Slide Over included). • Works in the background — close the screen, save battery. • Bluetooth output: route click to headphones or speakers. The mic for aiVolume™ stays on your iPhone / iPad, listening to your actual playing in the room. • Screen no longer locks while aiMetronome is on screen. • Clean, dark interface. Important: focus your device's mic 0.5–2 m from the sound source. Don't place the device directly on the instrument (e.g. on a piano body) — it can cause unnaturally high ambient readings and distort aiVolume™'s behaviour. --- NO SUBSCRIPTION, NO IN-APP PURCHASES --- Every feature in this app is included in your one-time purchase. Future updates are free. No "Premium" tier, no per-feature unlock, no ads, no tracking. The metronome you buy stays the metronome you have. --- FROM THE DEVELOPER --- I'm a musician, and aiMetronome started because I waited too long for one that behaved the way I needed. Every feature here exists because it solved a real practice annoyance. Made by a musician, for musicians. ainars

Verdict
The clearest difference is price: Trombone Tuner at Free against aiMetronome's $2.99. Trombone Tuner also leads on iOS requirement (12.0 vs 18.0). aiMetronome's advantage is in-app purchases (none vs 2) and ads (none vs shown). On device support there is nothing between them.
