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.

Geography turns a sound into a landscape. The sample is drawn as a cross-section of the Earth, from the burning core to outer space, and every grain of sound is a particle with weight that falls, bounces and sounds according to the layer it crosses. PLAY THE MATTER • Tap the terrain to drop grains, draw strings that ring when they're hit, and tilt your iPad or iPhone to change gravity. • Eight string materials: metal, wood, glass, skin, gut, bronze, bamboo and stone. • An on-screen keyboard of up to five octaves, or a continuous ribbon for gliding pitch. • MIDI: play from your keyboard and map its knobs to the app's with MIDI learn (endless encoders too, like the Akai MPK mini's). Program Change switches sounds. A WORLD WITH A LIFE OF ITS OWN • Six strata, each with its own weather: fire in the core, earthquakes in the geosphere, plants that bloom and release tuned spores, swell and bubbles in the water, wind in the atmosphere, satellites and comets in space. • Rituals: a sequencer of world events. The Moon, in its real phase, and the planets sing too. • Life: the instrument improvises, arpeggiates or mutates the sequence on its own. SEE IT IN 3D • Flat, Ridges, Living ridges, Surface, Point cloud, Planet and Sphere: seven ways to look at the same sound, with aurora, clouds and a free camera. THE LAB • Envelope, filter, two LFOs, echo, reverb, modulation (flanger, phaser, ensemble), scales and a 16-step sequencer/arpeggiator. • A mixer with one channel per sound source in the world, and a Space tab to place each source around your head, with scenes that morph on their own. THE REAL EARTH • Pick a place on the map and its live weather flows into the sound. Earthquakes from the last 24 hours shake the landscape. SAMPLER AND PRESETS • Sampler: record with the microphone or open a file, then trim, normalize, reverse and add fades. Up to 45 seconds, which become a landscape; it exports WAV too. • Save your sound under a name, with its settings and rituals, and export it as a file to move it between devices or share it. ON IPHONE AND IPHONE DUO • On iPhone, the world in full screen and a hidden dock with the essentials: play, draw, gyroscope, Life and the Ribbon. In landscape, Rituals, Earth, the Lab and the Mixer take the whole screen, and two fingers move, zoom and rotate the view. • Made for iPhone Duo too: closed, it is the world with the essentials, to play with one hand; open, the same world, bigger, with a keyboard in the dock and the panels in the middle of the screen. FOR YOUR STUDIO • Audio Unit (AUv3) for Logic Pro, GarageBand, AUM and more: every setting can be automated and is saved with your project. Stereo output, binaural spatial audio with head tracking, or 7.1.4, plus separate stems by source or by stratum. • Thirteen synthesized factory landscapes. You can also open your own sounds, or an image, which you hear as a landscape. Try it free (5 minutes per session). A one-time purchase unlocks everything on iPhone, iPad and Mac. No subscription. No accounts, no ads, no data collected.

Verdict

The call

The clearest difference is in-app purchases: Circlo at none against Geography's 1. Circlo also leads on ratings volume (5 vs 1) and iOS requirement (9.0 vs 18.0). Geography's advantage is update cadence (every 3 days vs every 33 months). On price, rating, ads and device support there is nothing between them.
