RISCy is a drag and drop synthesizer puzzle full of sonic perturbation. You live code via the limited instruction set in the lower part of the interface; drag out tokens to the top area to build your synth graph, drag a token back off the top area to remove it. Each token has an aural consequence, and some special tokens also change the nature of the hidden graph connecting active tokens; puzzling out these relationships is part of the fun. You'll be able to make lots of noisy sounds as well as generative sequenced patterns. Press ! to clear the graph and reset; press ? to get a random starting point. Download RISCy if you are open to stranger computer music sounds, and avoid it if you just want diatonic melodies and piano sounds!

Relic Flow is a generator of Lo-Fi rhythms, noise patterns and drum loops based on unique synthesis algorithms from NightRadio. More than 4 billion samples from the depths of the Mathematical Universe! Features: * search for new sounds with three buttons: next random set, edit code, previous set; each set of 12 sounds corresponds to a code of 8 characters; * three types of keyboards for live performing: on-screen buttons, PC keyboard, MIDI input; * several processing parameters + control via MIDI; * real-time audio recording to WAV (32-bit); * export to: WAV (one file or a set), SunVox (samples + effects in one file), text clipboard; * the LCK button freezes individual samples - they will not change during the search for new sets; * iOS Audio Unit Extension (AUv3). Double clicking on a parameter opens a window for setting the exact value. If you enable the Hold option, the notes will play endlessly, without reacting to key release (noteOff) events; turning the note on again works like turning it off; there are two ways to enable this option: 1) using the Hold parameter in the "MIDI Mapping" window; 2) by pressing the HOLD button, which appears in place of LCK while playing the musical keyboard: press HOLD, release the desired notes - then the released notes will continue to play.

Verdict
The clearest difference is price: RISCy at Free against Relic Flow's $1.99. RISCy also leads on iOS requirement (8.0 vs 12.0). Relic Flow's advantage is update cadence (every 17 months vs every 39 months) and ratings volume (26 vs 3). On rating, review sentiment, ads and in-app purchases there is nothing between them.
