## What is One Loop?

One Loop is a 10-track loop-station designed for singers, songwriters & instrumentalists. Whether you want a personalised backing track, or need to record an idea for your next big hit, One Loop brings performance and recording straight to your phone.

Features:
•	Simple, easy to use looping.
•	Built-in studio quality effects: Noise Gate, EQ, Compression & Reverb.
•	Advanced layer control and grouping. 
•	Metronome selection with a variety of backing percussion.
•	MIDI support and mappable control for hands free performance.
•	Supports external audio interfaces; up to 8 channels of audio input.

Recording

Whether you choose your device’s built-in microphone for quick and easy use, or an external interface for multiple routing options, One Loop encourages portable creativity. Don’t be restricted by the limitations of a computer when all you need is your phone… and something to record! 

Enjoy the app’s seamless looping and build up to 10 beautiful layers with ease. Save your projects for later reference, you’ll never forget those 3am ideas ever again! Make sure to wear headphones for clean recordings with no feedback issues.

Complete Control

One Loop gives you complete control to form your best ideas. Each layer is mute-able and has an adjustable volume slider to shape your overall sound. Assign each layer to a bank of 4 groups (A to D) for quick variation of instrumentation, or different sections of a song. 

Setup your Bluetooth or USB midi devices and assign their parameters to trigger any of One Loop’s functions for greater control and smooth performances.

Manage Your Mix 

One Loop gives you the controls to refine your recordings with studio quality effects designed by audio engineers: Noise Gate, EQ, Compression and Reverb. 

Wherever you’re recording, either in a quiet room or a busy outdoor environment, you can reduce any unwanted noise by adjusting the Noise Gate’s threshold and envelope, to create cleaner recordings.

Boost or Cut the Input’s EQ frequency bands (Low, Mid and High) with a +/- 15dB range to shape the sound of your loop layers.

Adjust the acoustic environment of your mix, from a small garage to a large cathedral, by changing the size & effect percentage of the Reverb.

Settle a busy, complex layered mix using the Bus Compressor’s threshold and ratio controls.

### 3/5 — Can’t load

*2025-08-22, version 1.1*

Love the app but it won’t let me upload any of my songs and the app crashes. Unfortunate…

### 4/5 — Great simple looper but….

*2025-07-06, version 1.1*

I love this app and how little latency there is with iOS audio. Being able to use drum beats instead of a click is great and the beats are sick. It always freezes on me when loading projects though and I really wish I could mute groups easier and have send controls over the fx per group. ALSO, I WOULD LOVE TO BE ABLE TO PAN LAYERS.

### 1/5 — Can’t remove metronome during playback.

*2025-02-12, version 1.1*

No matter what metronome selection combinations, you try, the metronome always got recorded over and over again during looping and built upon itself and just got noisier and noisier

### 5/5 — Great app but crashes when I load

*2024-11-04, version 1.1*

Great app but crashes when I load

### 1/5 — Crashes when loading files

*2024-10-24*

Lots of fun. Very limited unless purchased. Will save files but crashes when I attempt to load any file

### 1/5 — TLDR: Moneygrab/bad app designs

*2023-12-28, version 1.1*

This review is over the fact you have to pay to do basically everything 

Want more than three loops 
Gotta pay 

Want to add an effect 
Gotta pay

Want to add a different metronome 
Gotta pay 

It ruins the point of a loop app if you cannot actually make a proper loop 

Also there is no autosave and it never tells you to manually save it and so it has caused me to lose work

### 1/5 — Impossible to load recorded tracks

*2023-11-11, version 1.1*

I suppose we can save the tracks but impossible to load afterward !?
Email sent to developers: no answer.
App bought for nothing… just lost money.
I would recommend to use other looper.

### 4/5 — Can’t load saved loops :/

*2022-07-15, version 1.1*

Hi, I just bought the full version and it’s really fun and easy to use. I’d give it 5 stars if it didn’t have this one issue. For some reason. I can’t access saved loops. Every time I press “load”, the app freezes and I can’t do anything. Maybe I’m doing something wrong? I’m running the app on the iPhone 12 Pro. Anyway, besides that the app is great!

### 4/5 — YES (but)

*2022-03-02, version 1.1*

I really like this app. I find it straightforward and found my way in without getting lost or distracted. Up and running fast. I like the relatively rich options available in the metronome. So I will be using it as is in a sort of standalone way- but like many others would love to see it available in audiobus the same way other apps by this developer appear (tape emulator, compressors- each very good as well) looking online I see that many thought that audiobus iaa integration would happen in version 1.1 but that was a year ago I think- and did not include those features- hopefully soon 1.2 will !!

### 1/5 — Can’t delete anything

*2021-11-18, version 1.1*

Running on iPhone SE and I can’t delete any of my loops or start a new project
