Uber Synth is a polyphonic multi-timbral frequency modulated (FM) synthesizer that runs on any iOS device. The underlying sound engine is based on the triple-oscillator cross-modulated FM synthesizer first introduced in our xMod app. Uber Synth provides five multi-timbral options: 1) Mix the sounds of any two sound patches, 2) combine patches using the sound map, 3) Generate specified as well as randomized sound palettes across the keyboard, 4) Specify a region in sound space centered on a sound and move a point by a variable randomized amount within the region each time you play a note to create an evolving mix of the center sound and the sound nearest the point. 5) Do the same as above moving the point automatically at a specified rate. Supports Audiobus.

Train perfect pitch and ear training in 5 minutes a day. Hear a tone — name the note. Nine difficulty levels from beginner to chord progressions, free to start. Absolute Pitch Trainer turns ear training into a daily habit you'll actually keep. Hear a pure tone. Tap the note you heard. Watch your accuracy climb session over session — through nine levels of difficulty, from three coloured notes for absolute beginners to full chord progressions and melodies for serious students. THE SCIENCE Folk wisdom says perfect pitch is "inborn or never." That's only half the story. Children can develop full absolute pitch during a critical childhood window — especially with early musical training. But adult ears keep learning too: focused, repeated practice still sharpens accurate note recognition at any age. We built the app on the part of the science that works for grown-up brains. BUILT FOR REAL EARS • 9 difficulty levels — from 3 notes with colour hints to full chords and melodies • Two game modes — Practice (calm, no pressure) and Quiz (timed, scored) • Daily Challenge — a fresh test every day to keep the streak alive • Reference tuning fork — tap for a clean C-D-E-F-G-A-B reference scale • Clean pitch synthesis, no muddy waveforms PROGRESSION YOU CAN FEEL • XP and ranked progression from beginner to master • Two streak systems side-by-side — a daily-play streak that rewards showing up across sessions, plus an in-quiz answer streak that ignites an "On Fire" mode once you chain enough correct answers in a row • Achievement system across Common / Rare / Epic / Legendary rarities • Per-note mastery tracking — see exactly which notes you nail and which slip • Streak calendar showing every day you played this month STATS YOU'LL ACTUALLY READ • Historical accuracy curve — 7 days, 30 days, 90 days, or a full year of progress • Time played, total quizzes, correct answers, longest streak • Note mastery rings for every pitch class • Game Center leaderboards for career XP and best quiz score POLISH WHERE IT MATTERS • Four hand-tuned colour palettes (Tube Glow, Jukebox Chrome, Reel-to-Reel, Rainbow Pride) • Multiple alternate app icons • Optional daily reminders so a busy week doesn't break your streak • Six languages: English, Deutsch, Español, Français, 日本語, 简体中文 PREMIUM Premium unlocks the higher difficulty levels, advanced statistics, and exclusive app icons.

Verdict
The clearest difference is price: AbsolutePitchTrainer at Free against Uber Synth's $3.99. AbsolutePitchTrainer also leads on update cadence (every 2 weeks vs every 3 months). Uber Synth's advantage is in-app purchases (none vs 1) and device support (3 vs 1). On ads there is nothing between them.
