Aethron

Aethron is a minimal oscillator instrument for observing sound as waveform. Rather than a full music production app, Aethron is designed as a small sonic device for touching, layering, and reshaping oscillating sound. Add oscillators, tune frequency and amplitude, switch waveforms, invert polarity, sync phases, randomize signal states, and store the sounds you discover. Features * Multiple oscillators * SINE / SAW / TRI / SQR waveforms * Frequency and amplitude control * Fine frequency adjustment * SUM / SPLIT waveform display * RANDOM signal generation * POL +/- polarity inversion * SYNC phase reset * SOLO monitoring * STATES / STORE for saving setups * Automatic restoration of the last oscillator state Aethron is not a conventional synthesizer or a waveform viewer. It is a small instrument for touching invisible vibration through sound and waveform.

Verdict
The clearest difference is in-app purchases: Aethron at none against Soundipity's 1. Soundipity's advantage is iOS requirement (18.2 vs 26.5). On price, ads and device support there is nothing between them.
