Physicles vs rymdigare
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Physicles
This application provides physics-based Audio Unit MIDI plugins that generate MIDI messages through simulated physical interactions. It includes two distinct playgrounds: one with bouncing balls colliding with polygon sides, and another where balls interact with user-drawn segments.
- Physics-based MIDI plugin container
- Generates MIDI messages via physics engine
- Physicle Bouncy playground
- Physicle Gravity playground
- Compatible with AUM, AudioBus 3, and more
- Outputs MIDI only, no sound

NOTE: AU MIDI plugins are audio unit extensions that are meant to be loaded in compatible hosts, such as AUM, AudioBus 3, apeMatrix, Beatmaker, Cubasis 2, Nanostudio 2, or Sequencism. Please follow the instructions in the included manual. Physicles is a container of physics-based Audio Unit MIDI plugins. These AU MIDI plugins generate MIDI messages through the use of an underlying physics engine, which models the physical interactions between various entities. In this version, the following plugins are included: 1) Physicle Bouncy: In this playground, multiple balls bounce inside a polygon. MIDI messages are generated whenever a ball collides with the side of the polygon. 2) Physicle Gravity: In this playground, generators spawn balls every certain beats, which will then produce MIDI messages after colliding with user-drawn segments. Notes: - The plugins do not generate any sound, only MIDI messages.
rymdigare
This app is a versatile audio processing tool that combines reverb, noise generation, and sound degradation effects. It offers extensive control over reverb parameters, LFO modulation, and includes a resonant filter and octave shifter. It can be used as a standalone application or integrated with other music apps.
- Five reverb boxes with detailed control
- Noise and drone machine
- Level and speed degrader
- Resonant filter
- Octave shifter
- LFO modulation
- AUv3, Inter App Audio, AudioBus support

During a routine mining expedition in the outer regions of the galaxy five mysterious boxes of unknown origin were found. Rumours among the workers spread quickly that there was a strange feeling being around these boxes, as if time flows in a different way, not just forward but sometimes also folding back on itself. The miners nicknamed them, the five boxes of reverberation. After the excavation process, to study them more closely, it was decided to transport them back to earth. Rymdigare is part reverb, part noise and drone machine, part quality degrader and part wave shaper. The reverb is built from 5 reverberation boxes where you can control the sound with length and ratio parameters, tail and weight skew parameters and an internal feedback parameter, that could be used to create swelling tails. There is also a built in octave shifter, resonant filter, speed and level degrader and 4 LFO sources for modulating a selected set of parameters, including the LFO speeds themselves. The app can run stand-alone, connecting to other apps through Inter App Audio or AudioBus or it can run as an AUv3 plugin. Map and control any parameter with MIDI using Core MIDI, Bluetooth MIDI, Inter App Audio MIDI or AUv3 MIDI. + Resonant filter (low, band or high pass) + Noise and drone machine + Level and speed degrader + Wave shaper (input and output gain) + Reverb (length, ratio, skew, tail, feedback and type: free, bpm, tuned) + Reverb random variation controls + Octave shifter up and down + Planet orbits (LFO: double tap on parameter controls to map) + Inter App Audio, AudioBus and AUv3 + Map Midi CC using Core MIDI, Bluetooth MIDI, IAA Midi or AUv3 MIDI.

Verdict
The clearest difference is price: Physicles at Free against rymdigare's $4.99. rymdigare's advantage is update cadence (every 2 weeks vs every 3 months) and chart position (#189 vs unranked). On rating, review sentiment, ratings volume and ads there is nothing between them.
