cykle vs PolyPhase
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
cykle
This app is a powerful melodic step sequencer that generates complex musical patterns through the interaction of simple elements. It requires connection to a separate MIDI synthesizer app or hardware to produce sound. Offers extensive customization for musical parameters and sequence transformations.
- Semi-generative melodic step sequencer
- Decoupled sequencer lanes for musical parameters
- AUv3 MIDI plugin and standalone modes
- Sample-accurate sequencing engine
- Pattern snapshots and song mode
- Extensive sequence transformation actions
- MIDI clock output and Ableton Link support

cykle is an inventive, semi-generative melodic step sequencer for iOS, iPadOS and Mac (Catalyst). cykle abstracts every musical parameter into its own sequence using decoupled sequencer lanes, producing complex and musically engaging patterns from the interactions between simple elements. nb: cykle does not make sound by itself, you will need to connect it to a MIDI-compatible synthesizer app on your device, load it in an AUv3-compatible host (such as Logic Pro, Audiobus or AUM), or connect it to an external synthesizer, computer or any other MIDI-compatible sound generating device. features: - universal app (works on both iPhone and iPad) - works in both portrait and landscape mode - works as an Audio Unit (AUv3) MIDI plugin or as a standalone (CoreMIDI) app - sample-accurate sequencing engine - slick and responsive native UI - pattern snapshots selectable via MIDI input - song mode / pattern chaining - pitch playable by MIDI note input (arp and chord modes) - configurable tempo, scale and key - every channel can be routed to a separate MIDI destination and channel - every channel sends MIDI note- and pitch-bend data as well as an arbitrary number of MIDI continuous control (CC) messages - full AUv3 state- and preset-saving - randomization features - save and load patterns - decoupled sequencer lanes for the following parameters: - pulse - pitch - rest - step length - chance - velocity - accent - gate length - chance - ratchet (note repeat) - accidental (flatten/sharpen) - transpose - chord inversion - octave - harmonize - pitch bend - mappable MIDI CC values (e.g., filter cutoff, resonance, envelope, etc.) sequences can be instantly transformed by the following actions: - shift left/right/up/down - rotate - randomize - mutate - mirror - reverse - double - bisect - configurable clock division rate per sequencer lane - configurable playback mode per sequencer lane (forward, backward, random, jump) - MIDI clock output - Ableton Link support - works without internet connection - no push notifications - no ads or in-app purchases - no third-party behavioural tracking tools - ongoing development and support

PolyPhase is a generative sequencer! Melodies on a Master Track are created on the fly & copied, with phase offsets, to Follower Tracks. This structure, along with the interplay of various probabilities, leads to interwoven melodies and rhythms. You can disable the generation of notes & draw your own, or select some of the randomization functions Send MIDI to external hardware, other iOS instruments, or use the included wavetable synthesizer! - 8 independent Sequencers with their own rate, direction, transposition & other properties - Disable the generation of notes to draw your own, or use some of the intelligent functions provided - Random Euclid & Drum Sequences - The Wavetable Synth + FX lets you use PolyPhase even if you don't own any external Instruments - Filter notes to a Global Key / Scale and toggle Chord Masks - Save / Load Presets - Snapshots for install recall of your Sequences - Intelligently Randomize and Morph your Sequences & Synth sounds - Accepts external MIDI clock & can provide clock to other devices - Audiobus (Audio / State) & Inter-App Audio support - Link Support

Verdict
The clearest difference is in-app purchases: PolyPhase at none against cykle's 2. PolyPhase also leads on iOS requirement (10.0 vs 13.0). cykle's advantage is price ($12.99 vs $19.99) and device support (3 vs 1). On rating, review sentiment, ratings volume and update cadence there is nothing between them.
