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.

Nocturne LoFi is an immersive generative LoFi and ambient music studio for focus, reading, rest, sleep, and late-night creativity. Choose a scene and let its beats, melodies, and environmental textures evolve in real time. Nocturne does not simply repeat one short recording, so each session feels familiar without sounding exactly the same. 【11 IMMERSIVE SCENES】 Travel from Rainy Desk, Late Night Study, Midnight Café, and Night Train to VHS Memory, Forest Cabin, Space Radio, Harbor Dawn, Sunday Morning, Thunderstorm, and Rainy Day. Every scene has its own musical structure and atmosphere. Shape mood, BPM, tone, space, motion, stereo width, and ambience, or generate a fresh variation. Save favorite combinations and return directly to their scenes in Immersive Mode. 【BUILD YOUR OWN SCENES】 Import audio into the shared library, stack up to three layers, and adjust each layer’s volume, pan, and playback speed. Blend your sounds with a generated Nocturne bed to create a personal atmosphere. Choose a built-in vector cover or import, crop, and preview your own image. Pick a clock position, then enjoy your custom scene alongside the built-in scenes on the Home screen and in Immersive Mode. 【SHIMMER AND SOUND SHAPING】 Built-in Shimmer adds a bright, floating upper tail to the sound. Control Amount, Pitch, Decay, Tone, and Modulation, then combine it with warmth, drift, reverb, and the rest of Nocturne’s sound controls. 【FOCUS, SLEEP, AND BACKGROUND PLAYBACK】 Choose a 25-minute focus session, 45-minute deep-work session, or 60-minute sleep timer. Timers continue on the Lock Screen and in the background, pause playback when complete, and gently fade the volume near the end of Sleep Mode. Control playback from the Lock Screen, Control Center, headphones, and Now Playing. Supported iPhone models also show playback and timer status in Dynamic Island, while the Home Screen widget keeps the current scene and BPM visible. 【AUv3 FOR MUSIC CREATORS】 Nocturne LoFi includes both an AUv3 instrument and the Nocturne LoFi FX audio effect for compatible hosts such as GarageBand and AUM. The instrument supports built-in scenes and shared user audio, MIDI performance, host sync, a variable-length step sequencer, swing, ties, per-step velocity, triplet rates, and host project state restoration. Nocturne LoFi FX processes host input with tape warmth, Drive, Tone, Tape Age, Wow, Flutter, Dust, stereo width, Shimmer, and a tempo-aware sequencer. It also supports automatable parameters and effect bypass. The standalone app can discover and load compatible third-party AUv3 effects—including their custom interfaces—so you can build an effects chain around Nocturne. 【EXPORT AND SHARE YOUR SOUND】 Render the current scene as a stereo M4A file, or add it directly to the shared AUv3 audio library for continued use in the instrument and your custom scenes. 【ONE PURCHASE, COMPLETE EXPERIENCE】 Nocturne LoFi is a one-time purchase with no subscription. One purchase unlocks every scene, generative music, custom scenes, timers, audio export, iCloud sync, and AUv3 features.

Verdict
The clearest difference is rating: Nocturne LoFi at 3.7 against Uber Synth's 2.0. Nocturne LoFi also leads on update cadence (every 2 days vs every 3 months) and price ($1.99 vs $3.99). Uber Synth's advantage is review sentiment (50% vs 33%) and iOS requirement (14.0 vs 17.0). On ads, in-app purchases, monetization model and device support there is nothing between them.

Uber Synth costs $3.99 and Nocturne LoFi $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Nocturne LoFi holds the better App Store score, 3.7 against 2.0. Both are backed by a comparable volume of ratings — 1 and 3 respectively. Written reviews complicate that: 50% of Uber Synth's written reviews are positive against 33% of Nocturne LoFi's, so the app with the better star average is not the one people write more warmly about.
