The audio editor has very simple, uncluttered UI to allow users focus on their tracks. Behind the simple interface however you can find lots of useful tools and capabilities, such as fade in/out, normalise volume levels, reverse time, and basic synthesis. With this powerful audio/music editor on iPhone, you can record tracks, import tracks from Music library, import audio/music from iPhone or a cloud service, trim, cut, copy, paste, delete tracks or your selection, edit multiple tracks side-by-side, mix them together, export to Wave or MPEG 4 (AAC) format, transfer to your computer via a cable, or cloud service, send to another app on your iOS device, upload to various cloud services.

First time writing an App review.

I tried many free apps for audio editing, but nearly all were trying to push adverts or were just not upto the mark! Too many hidden problems!
This app by Hokusai is a real gem! It does almost everything you might want on the free app, without buying the pro version. I could do trimming, duplicating, pasting, adding tracks together, zooming to see detail in the wave pattern, exporting the finished project as an .mp4 file but still easily playable (after importing individual tracks as mp3). Easy to bring in tracks via WiFi sharing. All of this I could do within a few mins of trial and error practicing. So easy to learn without reading a manual ~ Thank you developer for a genuinely great app. Never asked me to upgrade or buy anything after a full day’s use.
So far, really so good!

Great for on-the-go editing

I moved completely to iPad recently, and thus lost the audio editing capabilities I had on my MacBook. As I looked for a replacement editing software, I found many mediocre substitutes. It was with this app that I found all of the features (some through the pro upgrade) that I needed for successful podcast editing. All—in—all, this is a very intuitive app with a great Ul. I appreciated the ease of audio editing on iPad after using this app.
Favorite features: Apple Pencil integration, noise cancellation, and overall easy editing interface.
Unhelpful features: I cannot figure out how to keep the scrolling needle in view. Perhaps integrating a scrolling sound wave that moves with the needle, especially once it moves off the screen.
Thanks, again!

Amazing app, amazing service

Wooji Juice has made the best possible impression on me. Both for the ease of use of apps, the quality and functionality of said apps, but also a consistently friendly and immediate response to questions/concerns. Did I mention l’m 100% blind, and I’m still able to make use of this and Ferrite? Even Apple’s native DAWs and voice recorders aren’t this user friendly. Wooji Juice, thank you so much. Suggesting this to all my musician friends, whether sighted or blind.
This is truly a great app!
