Circlo is an ambient audiovisual clock. The ambient soundtrack by Hannu Kuosmanen changes depending on what time of day it is while the circles on the screen pulsate gently. The music is at its calmest around 1 am/pm, and gets more intense until the clock strikes 1 again. Double-tap anywhere to access the settings screen where you can change the color scheme and turn the music on or off. Design and programming by Johan Halin. Music by Hannu Kuosmanen. --- Johan Halin has also created Kontrol, an experimental techno composition that was shown in 2011 at the Museum of Modern Art in New York as part of the "Talk to Me" exhibition, and Revolve, an ambient reaction game.
Aethron
Read full descriptionHide full description
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.

The clearest difference is device support: Circlo at 3 against Aethron's 1. Circlo also leads on iOS requirement (9.0 vs 26.5). On price, ads and in-app purchases there is nothing between them.
