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.

ON'NENIKUR is an octave-freeze reverb app for iPhone and iPad. It can be used as a standalone audio app or as an AUv3 effect inserted into compatible host apps such as GarageBand. This processor blends standard-pitch reverb with a pitch-shifted dry signal before applying modulation, filtering, envelope shaping, and dry/wet mixing. “DARK” shifts the original sound down an octave to create a rich, spacious sound, while “LIGHT” shifts it up an octave to produce a brighter, more ethereal sound. “FREEZE” transforms the reverb tail into a playable hold texture. Features - Octave-down (DARK) and octave-up (LIGHT) reverb - Two reverb paths: standard pitch and pitch-shifted - FIR (chorus-style) and OAK (phase-style) modulation modes - RISE (swell) and FALL (standard envelope) - Adjustable filter, decay, mix, octave level, depth, rate, and output - “FREEZE” for creating sustained textures and drone sounds - Instrument input mode and line input mode - 2x and 4x processing modes to control the quality of the octave shift - Standalone iOS/iPadOS app - AUv3 audio effect Trial Before Unlocking The trial version of this product is designed to allow 10 minutes of active use of all features across both the standalone app and the AUv3 plug-in. A one-time, non-consumable in-app purchase unlocks unlimited use in both formats. The “Restore Purchase” feature is also available in the standalone app. ON’NENIKUR is designed for shoegaze, ambient, post-rock, and any arrangement where guitars, synthesizers, vocals, and reverb are integral parts of the song’s composition.

Verdict
The clearest difference is price: ON'NENIKUR at Free against Uber Synth's $3.99. Uber Synth's advantage is in-app purchases (none vs 1) and iOS requirement (14.0 vs 16.0). On ads and device support there is nothing between them.
