SECTOR vs apeDelay
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
SECTOR
This app allows musicians to slice and sequence audio loops using a probability-based matrix and a classic step sequencer. It offers time-bending effects for unique sound manipulation and real-time performance tweaking, bridging the gap between controlled patterns and random sonic exploration.
- Probability-matrix sample slice sequencer
- Classic pattern step-sequencer
- Time-warping transfer functions
- Real-time performance tweaking
- Import custom loops
- Inter-App Audio and Audiobus support
- MIDI Clock sync

Proud winner of a 2015 Electronic Musician Editors’ Choice Award! Slice and sequence your loops with a matrix of markov-chain connections. Introduce order with the probability based coin-flipping pattern sequencer. Bend time with warp functions for glitches and modulations. Tweak and trigger in real time performance. Get anything between rigid control and random chaos. • Unique probability-matrix sample slice sequencer • Classic pattern step-sequencer for absolute control • Time-warping transfer functions for various effects • Includes high-quality loops by Richard Devine, Sonic Mayhem, Arovane, Alex Matheu and Sunsine Audio • Import custom loops from other apps, AudioShare, Pasteboard or using iTunes FileSharing • Stream audio to other apps via Inter-App Audio or Audiobus • Synchronize to Inter-App Audio hosts such as AUM, Auria or Garageband • MIDI Clock slave/master to sync with other apps or hardware • MIDI control for triggers, volume, start/stop, and loading projects • Supports Audiobus Remote triggers • Record and export the results as perfectly synchronized loops • Audiobus state saving "One of the most innovative and entertaining audio apps you’ll ever encounter" - David Biedny at MacLife.com "Engrossing, beautiful, wild and a fine addition to the iPad studio" - Computer Music Magazine "This is already, I think, a must-buy. Going to have fun playing with it. Enjoy!" - Peter Kirn at CreateDigitalMusic.com "It is utterly brilliant" - John Walden at MusicAppBlog.com
apeDelay
This audio effect app transforms sound by converting it to the frequency domain for manipulation, then back to the time domain. It offers advanced spectral effects like blur, granulation, and filtering, with extensive control over delay lines and feedback.
- Spectral delay with up to 2048 lines
- STFT analysis/re-synthesis
- Spectral Blur, Granulate, Decimator, Freeze
- Brick-wall filters
- AudioUnit V3 (FX) and Inter-App Audio (FX) support
- Audiobus (Full) and Ableton Link integration
- Built-in Stereo Sampler

apeDelay - spectral Delay implements up to 2048 delay lines with feedback or up to 2048 Brick-wall filters. The algorithm is based on the STFT (i.e. Short Time Fourier Transform) analysis/re-synthesis. The audio signal is converted in abstract ‘Frequency Domain’, where is manipulated and transformed back again in ‘Time Domain’. You can draw the Time and Feedback shapes for both stereo channels. This is achieved from the multi sliders, who provide a great tool to manage the huge numbers of parameters. You can also benefit of more advanced spectral manipulations like the Spectral Blur, Granulate, Bins Decimator, Noise Gate, Spectral Freeze and Brick-wall filters. + AudioUnit V3 (FX) + Inter-App Audio (FX) + Audiobus (Full) + Ableton Link + Audio Interface support + Microphone input + Built In Stereo Sampler with varispeed and scrubbing + Control Manager LFO for all the Parameters + Midibus, Virtual Midi and Network: 14 bit NRPN controllers + Sample Manager, sharing common audio files via iTunes, Dropbox and AudioCopy + Snapshots Presets Morphing Pad + Post Fx: Stereo Delay, Amazing ClassicVerb Low/Hi Shelving and Dynamic Processor + etc...

Verdict
The clearest difference is ratings volume: SECTOR at 87 against apeDelay's 17. SECTOR also leads on iOS requirement (9.0 vs 17.0). apeDelay's advantage is price ($7.99 vs $8.99). On rating, review sentiment, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
SECTOR costs $8.99 and apeDelay $7.99 up front. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 4.7 for SECTOR against 4.6 for apeDelay. That said, the two scores are not equally well evidenced: SECTOR has 87 ratings behind it against 17, so its average is the more settled of the two. Written reviews are what separate them: 90% of SECTOR's written reviews are positive against 88% of apeDelay's.
SECTOR ships an update every 3 months, apeDelay every 4 months. The most recent releases landed on October 23, 2026 and October 29, 2026 respectively.
