'sinusedo' is a sinewave synthesizer in standalone and AUv3 formats. It features two independent keyboards with: • 4 – 72 keys (voices, steps) per octave, each with its own ring modulator • maximum polyphony equal to the number of voices; max polyphony is 144 voices • 1 – 4 octave range, covering the frequency range of about 8 – 4200 Hz • display with note number (from C), note name, frequency (in Hz), and deviation from 12-TET (in cents) • two sections per keyboard: upper for non-sustained notes, gliding, and velocity; lower for sustained notes and modulation rate • mute button to stop/start all sound • delete/panic button to erase all notes • glide button for smooth sweeps across keyboard frequency range • modulation on/off button • slider to set initial velocity and modulation levels • slider to change velocity and modulation rates for all notes on the keyboard proportionally and to show current velocity and mod rate levels • button to toggle keyboard visibility. sinusedo supports MIDI input from external sources to control each keyboard independently. Supported devices: iPad, iPhone
Ringotron
This app offers advanced control over ring modulation effects for sound design and audio processing. Its multi-band design allows precise manipulation of the audio spectrum, with a special soft mode to reduce unwanted intermodulation. It can also function as a resonant filter that smoothly transitions into a ring modulator.
- Parallel ring modulator units
- Stereo separation control
- Ultra-narrow band resonance
- Ribbon controls for frequencies
- Modulation system for band centers
- Tempo syncing for oscillators
- Soft limiter and clipper

Ringotron allows taming the strong transformational effects of traditional ring modulation, opening up a wider range of possibilities in sound design and audio FX. Its multi-band design enables fine control over which parts of the spectrum will be transformed by the effect. A special soft mode is available that borrows concepts from feedback modeling, which can be used to reduce intermodulation effects that are often a limiting factor in the more general applicability of ring modulators. In addition to the layers of control they provide, combination of these core features also allows the plugin to act as a stereo, multi-peak resonant filter that can also smoothly morph into a ring modulator. FEATURES: • 2 parallel ring modulator units (max. modulator frequency: 8 kHz) • Stereo separation can be added to band center, mod. frequency, mod. phase • Ultra-narrow bands can be used to create highly resonant sounds • 4 large ribbon controls for band center and modulator frequencies • Band center frequencies can be modulated by the built-in modulation system • Tempo syncing can be independently configured for each oscillator • Built-in soft limiter and clipper to protect against volume spikes IMPORTANT INFORMATION: The plugin comes with a zero-latency, non-brickwall soft limiter, and as such, its stopping power is limited. Make sure to always leave enough headroom or use an external brickwall limiter for total protection against powerful transients. Alternatively, a built-in soft clipper is also available. PLEASE NOTE: • AUv3-compatible host app is required • Suported sampling rates: 44.1, 48, 96 kHz

Verdict
The clearest difference is update cadence: sinusedo at weekly against Ringotron's every 20 months. sinusedo also leads on price ($3.99 vs $8.99). Ringotron's advantage is rating (5.0 vs 4.7). On review sentiment, ratings volume, ads and in-app purchases there is nothing between them.
