And of course, pre-existing Hokusai 1 or Hokusai 2 purchases are supported in Hokusai 3: if people update the app, but decide not to subscribe, they won’t lose out.

Wooji Juice @wooji-juice.com · 21/09/2026

Hokusai 3 Pro is a subscription, yes. Some people have a philosophical objection to subs, I know I won’t be able to change anyone’s mind on that, but from a practical point of view, at $9.99/year (_not_ month!), Hokusai is extremely accessible, equivalent of less than $0.84 a month.

In 26, for all the talk, the end result was often buttons that were just “white background, bit of a drop shadow”. This year feels like they actually delivered on what we were promised. Love the subtle green reflections of the VU meters on the recording button in the screenshot above.

Ready for iOS 27, I’ve released the Ferrite 3.3 update. Includes significant speed boosts when exporting CAF or M4A files. Also released? Hokusai 3 and Hokusai for Mac! Huge update/new app! And have I mentioned how much I like Liquid Glass in the 27 OSen?

A USB Audio Device is connected, with 8 channels, each with their own VU meter arranged around the record button, which softly reflects their green bars. They also have dotted lines indicating the recent peak audio level.Below, the Headphone Monitoring menu button, the Input Gain dial, and the Normalise Recording switch.

Dev Support always used to be pretty good. I guess App Store Review isn't the only part of Apple's infrastructure getting DDoS’d by vibecoders…?

020

Wooji Juice @wooji-juice.com · 14/08/2026

After more than 6 weeks, Apple have finally(!) fixed the issue preventing me from upload a TestFlight build of Hokusai for Mac. 🎉 Submitted, pending approval. If you haven't jumped on the TestFlight yet, now's a great time to do so!

110

Wooji Juice @wooji-juice.com · 30/07/2026

Hokusai 3 in motion. TestFlight URL is at the end :)

031

Wooji Juice @wooji-juice.com · 30/07/2026

A modest iOS 27 update for Ferrite is planned for the autumn.

100

Wooji Juice @wooji-juice.com · 30/07/2026

It's on the list of things I'd like to add at some point, but nothing to announce now.

100

Wooji Juice @wooji-juice.com · 29/07/2026

The goal is to release Hokusai 3 around the time of the OS 27 updates, but it'll depend on A) how the TestFlight goes, and B) whether Apple actually fix their issue that's preventing macOS builds from uploading. But iOS TestFlight is now available! Visit our website and add testflight to the URL :)

Wooji Juice @wooji-juice.com · 29/07/2026

Today, I want to pull back the curtain on Hokusai 3 — going into TestFlight beta testing soon, I'm looking for plenty of people to kick the tyres. Rewritten from the ground up, with a beautiful, colourful new design and a _whole bunch_ of the most requested features!

Wooji Juice @wooji-juice.com · 29/07/2026

I suppose I should say, if you're wondering why we have two audio editors, Ferrite is laser-focused on spoken-word (podcast, radio, audiobook etc) editing. Hokusai is your audio multitool for everything else. More here: www.wooji-juice.com/blog/hokusai...

The Difference: Between Hokusai Audio Editor and Ferrite Recording Studio

010

Wooji Juice @wooji-juice.com · 29/07/2026

It was kinda basic at the time; looking back, I'm amazed it worked at all: we still had to support devices with just 128MB of memory, half reserved for iOS! Since then, the biggest change was Hokusai 2, which adopted a very “flat” design. It's... okay? This is what's currently in the App Store:

A screenshot of Hokusai 2 running on iPad in 2019. Retina resolution, flat design, lightweight glass sidebar and modern icons. It looks much cleaner, but also very plain.

110

Wooji Juice @wooji-juice.com · 29/07/2026

About 15 years ago (summer 2011) we released Hokusai Audio Editor. It looked like this — before Retina, when the only screen sizes were “iPhone” or “iPad” and you had to design each in a separate file:

A screenshot of Hokusai 1 running on iPad back in 2011. Non-retina, with a skeuomorphic wood-grain background and some very dated-looking buttons.

120

Wooji Juice @wooji-juice.com · 28/07/2026

It’s now been 1 month(!) (almost to the minute!) since I filed an Apple Developer Support request for them to make the change necessary to upload macOS builds of the thing I want to announce. Still waiting. I think that, tomorrow, I'll just go ahead (iOS only) & hope they get their act together soon

000

Wooji Juice @wooji-juice.com · 01/07/2026

I wish! Sadly no, but that’s next on the list of things to look into, after this is (fully, not beta test) released. Plus, many lessons learned when it comes to making professional editing apps cross-platform between iOS/Mac, that should be applicable to Ferrite.

210

Wooji Juice @wooji-juice.com · 01/07/2026

All this is by way of saying, I really hoped to announce something today, but first I want to have TestFlight builds ready for people to try — so it might be an extra few days while things get resolved, new builds (with new IDs baked into them) are uploaded, then have to wait for approval.

110

Wooji Juice @wooji-juice.com · 01/07/2026

This is because (around 15 years ago!) Apple changed a technical aspect of how their systems identify apps, and the Mac App Store doesn't support the old version. Bonus fun fact: developers themselves _can't fix this_. Fortunately, Apple Dev Support apparently can… eventually.

110

Wooji Juice @wooji-juice.com · 01/07/2026

So here's a fun fact — and by “fun” I mean “weird and annoying”: If you made an iOS app so long ago it was before the Mac App Store existed, then go to add a Mac version now, the App Store throws it back in your face when you try to upload it.

110

Wooji Juice @wooji-juice.com · 30/06/2026

About to upload (beta test) builds of something I've been working on for well over 2 years. Feels strange, like I must've forgotten _something_, but everything seems to check out…

110

Wooji Juice @wooji-juice.com · 12/06/2026

For prompt replies to questions, you can contact Customer Support by email using the in-app links. I wouldn't expect a large library to slow down the app in general (e.g. editing), but the library itself _might_ refresh more slowly with a very large library, but it depends on various factors

000

Wooji Juice @wooji-juice.com · 19/05/2026

If you're encountering a problem, please contact Customer Support by email, using the link inside the app, providing some more details so we can investigate. Thanks!

200

Wooji Juice @wooji-juice.com · 13/05/2026

Just checked (unzipping a larger audio file, over 200 MB) on an M2 iPad Pro, and it was essentially instant — barely saw the progress bar appear. If this isn't your experience, please contact Customer Support using the link inside the app, providing some more details so we can investigate. Thanks!

100

Wooji Juice @wooji-juice.com · 30/03/2026

I’m sorry to hear you’ve encountered a problem importing audio into Ferrite. For technical support, please contact us via email using the Customer Support link in the app’s Tools menu, as we can’t diagnose issues over BlueSky. Thanks!

010

Wooji Juice @wooji-juice.com · 16/02/2026

And the results propagate throughout the interface courtesy of SwiftUI & the Observable macro. Just… quietly satisfying.

010

Wooji Juice @wooji-juice.com · 16/02/2026

Today I finally switched it on for The New Thing — the sync engine uses Swift generics to support all kinds of data — and it Just Works™️, changes syncing after a few seconds (I have deliberate throttling set on it, it doesn’t need to be instant).

100

Wooji Juice @wooji-juice.com · 16/02/2026

About 18 months ago, I created a custom sync solution for Transcriptionist, for “data that isn’t a document, but is still too big for NSUbiquitousKeyValueStore”. It was probably overkill for that app alone, but I knew I’d be using it more widely…

100

Wooji Juice @wooji-juice.com · 16/02/2026

I’m sure I’m just showing my age here, but I still like the magic of adding cloud sync to an app and watching stuff flow seamlessly between devices. Networking was always a big deal to me even back when it was just a serial cable between two machines.

140

Wooji Juice @wooji-juice.com · 15/12/2025

This defines a `func corners(in size: CGSize?) -> Corners?` method you need to implement, and those are the corner radii the glass highlight will use. It’s pretty straightforward once you know, but I haven’t seen it documented anywhere as affecting interactive Liquid Glass.

000

Wooji Juice @wooji-juice.com · 15/12/2025

But you can force it to use a roundrect of arbitrary radius — limited, but great if you're rendering (say) a "speech bubble" shape, as you can at least get it to highlight everything except the "tail”. How? Well, you need to implement the `RoundedRectangularShape` protocol.

100

Wooji Juice @wooji-juice.com · 15/12/2025

iOS 26 Liquid Glass + SwiftUI thing I recently discovered: If you're using `glassEffect(in:)` with a custom Shape, and you're using "interactive" glass, it'll render the interaction highlight as a capsule, _not_ your custom shape. This will often look bad because of the mismatch, esp. at corners.

100

Wooji Juice @wooji-juice.com · 10/11/2025

It would require writing a new macOS version of the app from scratch.

100

Wooji Juice @wooji-juice.com · 05/11/2025

A lot's changed since then! From MP3 export to multichannel recording to Apple Pencil and mouse support, customisable keyboard shortcuts, windowing, auto levelling, advanced search and smart folders, and much more!

A screenshot of Ferrite’s main library/recording screen, running on iPad, back in 2015 — in the days before Split View or windowing, before multichannel recording, MP3 export, mouse or pencil support, and so much more.

Wooji Juice @wooji-juice.com · 05/11/2025

Exactly 10 years ago today, Ferrite 1.0 was released to the App Store! It's been a pretty wild decade. Here's to 10 years of Ferrite, and many more to come…

120

Wooji Juice @wooji-juice.com · 13/10/2025

A Mac version of Ferrite is something we're very interested in, but unlikely to appear soon.

100

Wooji Juice @wooji-juice.com · 01/10/2025

mono, low sample rate, low bit rate — all-round bad. Ferrite will detect this & warn you, but still, it’s not ideal. So it only enables this when requested — otherwise, anyone trying to edit (not record) using non-AirPods Bluetooth headphones would hear their sound quality trashed.

010

Wooji Juice @wooji-juice.com · 01/10/2025

…which means high-quality AirPods recording doesn’t work unless you also enable *low-quality* Bluetooth recording. And enabling *that* destroys the audio quality of *both* recording *and* playback if you connect any other Bluetooth headphones. By “low quality”, I mean old-school phone call level:

110

Wooji Juice @wooji-juice.com · 01/10/2025

Ferrite 3.2.1 is out today, with support for high-quality recording from AirPods (with H2 chip: AirPods 4, AirPods Pro 2 or 3)! apps.apple.com/app/id101878... Note: this requires iOS 26, and you’ll need to enable the feature in Ferrite, Tools → Settings → Recording. Why? Well, an iOS 26 bug…

Hello! Sorry to hear you've had a problem with Ferrite on iPad OS 26. That's not something I can diagnose over social media, but if you get in touch by email I can look into that for you. wooji-juice.com/contact

000

Wooji Juice @wooji-juice.com · 06/08/2025

And finally, there's one more thing I hope to be able to announce soon:

010

Wooji Juice @wooji-juice.com · 06/08/2025

One day I'd love to make a new synth with all the mod cons, but right now other things are higher priority. So if you want some synths that don't support AUv3, aren't likely to get updated, BUT make really cool sounds, get 'em before they're gone: www.wooji-juice.com

wooji-juice.com

Home

010

Wooji Juice @wooji-juice.com · 06/08/2025

Some bad news regarding our synthesisers: I think this is the year we'll have to retire these, probably this month. Shame, as I love them, but they've had a good run (the "new" one is over 10 years old!) and predate all sorts of modern development tech like Swift, SwiftUI, and AUv3.

110

Wooji Juice @wooji-juice.com · 06/08/2025

• …doesn't support as many languages though. Might be hard to “message” in UI. • Also really want to add iPad menu support, but currently blocked by SwiftUI bugs (FB18799723) (Ferrite uses UIKit Lifecycle, which is why it has full iPad menu support…)

010

Wooji Juice @wooji-juice.com · 06/08/2025

Next, Transcriptionist: • Background transcription — won't be as widely available, as transcription needs GPU & fewer devices support background GPU use • Exploring use of Apple's transcription API. Preliminary tests seem promising — not as accurate as existing large brains, but quick and efficient…

110

Wooji Juice @wooji-juice.com · 06/08/2025

(screenshot should give you a fair idea what to expect). • Pretty comprehensive iPad OS 26 menu support. • Also experimenting with support for the new AirPods high-quality recording mode.

000

Wooji Juice @wooji-juice.com · 06/08/2025

First up, Ferrite: • Continue exports in background, track progress in a Live Activity (note: it'll still be possible for exports to get cancelled if other apps require too many resources) • Lightly updating UI for Liquid Glass. Don't expect complete rethink — that's not something to rush into.

A screenshot of Ferrite Recording Studio running on iPad OS 26, showing a Liquid Glass sidebar and the new iPad menu bar, with the File menu open to the Export submenu, showing various export types.

130

Wooji Juice @wooji-juice.com · 06/08/2025

I thought I'd take a moment to provide a sort of mini-roadmap for Wooji Juice's autumn app updates. Note that iOS 26, macOS 26 and iPad OS 26 are all kinda “coming in hot”, so, don't take _any_ of this as promises, it'll depend on the state of the OSen. But these are our plans…

010

Wooji Juice @wooji-juice.com · 04/07/2025

e.g. their View menus don’t contain any commands for changing the browser view (icons vs list view, sort order, etc), File/Edit contain nothing for selecting, sharing, moving, deleting files, etc.
