### 3/5 — 動画再生時の使いづらさだけ改善されれば…

*2025-12-30*

タイトルの通りです。Tab付きの動画を一時停止して確認したい時に、停止時は再生コントロールが表示されたままになるのでTabに被って全く見えなくなり練習になりません。どうかここだけは改善をしていただけると…！

### 2/5 — Doesn’t rotate

*2025-12-29, version 1.2.0*

The app is great for
Mix and setting the GO but the app it’s self does not rotate when in landscape mode. If they update the app to do so my rating would be higher.

### 2/5 — Ok-Could be much better with small tweaks!

*2025-09-25, version 1.2.0*

The biggest pain is always having to sign in because the session has ended. I also hate that my library disappears randomly!

### 3/5 — Let it rotate.

*2025-07-28, version 1.2.0*

Great app on the phone. Using my iPad for practice and this singular issue is really problematic/awkward here. Even letterboxing the whole interface and shrinking to fit as an iPhone app on iPad landscape would be preferential to forcing the ui to keep (a very large) portrait mode on this device.

### 2/5 — No landscape mode on iPad

*2025-07-22, version 1.2.0*

We are in 2025 and an iPad is a great tool for musician, but an iPad mostly stand in landscape, not portrait. How can you create an app that doesn t support landscape on iPad in 2025?

### 2/5 — 途切れる

*2025-03-07*

アプリ内でYouTubeを再生出来る機能があると思いますが、再生中に高確率で音声が途切れます。リズムがズレてしまうため、動画に合わせて演奏したい人や動画を撮りたい人にとっては致命的な不具合だと感じます。早急に改善をお願いします。

### 3/5 — Kein Querformat

*2025-02-24*

Finde die grundsätzlich OK. Jedoch unterstützt sie auf dem iPad kein Querformat. Das sollte meines Erachtens heutzutage nicht mehr sein.

### 3/5 — iPadで

*2025-02-23*

楽しんでいますが、横向きにも対応してくれないでしょうか。

### 1/5 — わかりにくい

*2025-02-15*

使用方法のマニュアルが必要と思う。特にパッチの保存関係は分かりにくい。

### 1/5 — App not connecting to new iPad Pro (m49

*2025-01-04*

The app worked ( morer or less) on iPhone 8 and iPad Air2 but it cannot connect MIDI to the new iPad Pro. Now what...

### 2/5 — このアプリが残念すぎる

*2024-12-10*

Bluetooth接続の時は音量調整できるがオーディオインターフェースとして使おうとするとBHMが爆音で流れて調整できない。ヘッドフォンアンプとしては有能なので早急なアプリの改善を求む。

### 3/5 — Gute App, aber…

*2024-10-21*

zwei Dinge, die optimiert werden konnten:
1. Patches sichern oder laden hätte viel einfacher gestaltet werden können
2. Sessions von YT bringen eine Bot-Fehlermedung. YT Videos lassen sich nicht mehr laden.

### 3/5 — Far too many bugs

*2024-10-17, version 1.1.1*

I’ve give 3 stars because this product and the app have promise but on my iPad I am frustrated by the large number of bugs.

I have provided a long list to Roland tech support several weeks ago, who have been very understanding but unable to resolve yet. They said the issues will have to go back to the Japanese development team to fix.

In the meantime, daily practicing with a backing track is annoying to say the least.

### 1/5 — Nt katanas boss tone

*2024-09-29*

Did not work for me so I just deleted it

### 1/5 — Doesn’t connect

*2026-07-01, version 1.2.0*

Follow all the instructions. Factory reset, download latest firmware etc but just won’t connect to the device. Pretty useless really.

### 1/5 — Bluetooth aspect not very functional

*2026-05-02, version 1.2.0*

Would not recommend getting this product or app not easy to set up and have to do setup multiple times just to get it to work and you have to do it all over again every time you wana use it needs serious work

### 1/5 — 接続されない

*2026-02-09*

説明書を見てスキャンしても表示されない

### 1/5 — アプリとiPhoneが接続できない。

*2025-10-20*

何度試してもSCANから一向に検知してくれず、アプリを再度インストールしたりしても不可
Bluetoothを一旦接続解除してペアリングしなおしても反応なし。どうすりゃいいねん

### 1/5 — わかりにくい

*2025-10-13*

せめて日本語に対応してくれ

### 1/5 — 不安定

*2025-09-08*

バグが多い。セッションで音が出なかったりするし、なんとなくテンポも速くなってきたりしてるような気もする。不安定。

### 1/5 — This is the worst

*2025-07-28, version 1.2.0*

Worst invention ever impossible to connect do not buy the boss katana go if intending to use app you will not succeed

### 1/5 — EV-1-WL

*2025-05-28*

EV-1-WLを接続してもエクスプレッションペダルとして機能しません。もう一年位機能してません。改善お願いします。

### 5/5 — Nailed it!

*2026-08-12, version 1.2.0*

The boss katana go is my favorite piece of gear now. I use it for guitar and bass. I play along with music streaming on my phone over a Bluetooth connection while walking around outside. It also works as an audio interface when plugged into newer iPhones via usb-c connection. So much tech in a small inexpensive package.

### 5/5 — it's great

*2026-06-05, version 1.2.0*

Great, easy to use, everything is there. I just wish it was also available for macOS or at least if Roland could let us use it like some other bts product which the iOs can be on macOS. 

Come one ! please ! 🙏

### 5/5 — Needs a better UI

*2026-01-31, version 1.2.0*

The only thing holding it back for me is the UI (user interface) it needs more graphics (buttons, knobs, switches). Just showing numbers isn’t enough specially for new guitarists. This app acts as if everyone knows what all these settings are. Other than that this is a great app to go along with the Boss Katana Go.

### 5/5 — nah

*2026-01-01, version 1.2.0*

The app is absolutely fantastic. You can literally stream backing tracks from your phone to the amp!!! If you know how to use a phone, you can get around the app. All I will say: sounds slightly less better than fenders Mustang headphone amp.

### 5/5 — Works Great

*2025-02-25, version 1.2.0*

Has worked great for the year that I have used it with my Katana Go. No issues with using the app to mention for me.

### 5/5 — Awesome piece of gear!

*2024-10-05, version 1.1.1*

For the price point of the KatGO, the complainers want what you would get out of a unit 5 times the cost. Ignore them. I’ve owned Boss gear since 1985, trust me when I say that technology and convenience has come a 
L O N G way. Following the connectivity instructions to a “T” via Bluetooth is vitally important, if not then you’re “dead in the water” so to speak.
The mere fact of dialing in 60 onboard Boss effects via phone or tablet precisely how you want and whenever you want without wires and cables or bulky pedalboard is appreciated beyond measure!

I completely love and appreciate that I can import my Katana 100 head mkII .tsl patches to the KatGO via iCloud and they sound EXACTLY like I was plugged into my studio with headphones.

As for the complainers that want more than what Boss claims it would do, just simply ignore (they didn’t contribute a single thing towards the development and implementation of the KatGO nor the lines of code used).

Follow the instructions on setup EXACTLY as worded. I didn’t the first try and automatically determined it was user error and not flawed technology. I followed exactly the second time and it works flawlessly now.

### 5/5 — Love it

*2024-09-06*

Best money I have spent on a tool to help me practice. 

It has something for everyone. I personally use the presets and just use my guitar controls with the katana go volume knob to do tweaks. I love this as I personally don’t want to mess around with settings in the app too much right now. There is a ton of features in there to mess with when I do get to that point but I love that it’s optional. 

Sessions is where I do use the app a lot. It allows me to add tracks that I want for practicing. Some really great features in there for marking points in a track and tempo control. For me I just created playlists in Apple Music and then sync them to my phone. From there I can import tracks in and use them for practice. I have also used web links and it worked as I expected. 

Librarian is great for saving tweaks as presets that I can use again later. Also being able to just jump back to the presets on the device is great. I have not messed with many of the user created sets but I have downloaded all the Boss ones and they are very fun. I mostly stick to the presets that came on the device though. 

Used tone studio to download all the boss created sets. I find it fun to swap it up a little from time to time. 

My general workflow is using the built in tuner before playing, selecting my preset from the device, opening sessions, and running through tracks I am practicing. I switch from sessions to using a metronome app on my phone. 

All this is super simple and makes practicing very easy to do. Super minimal and mobile solution that covers all my needs. 

I hope they do sort the Katana Go out in the future and offer it again. I am a hobbyist and do not really need an amp for my needs, but this checks all the boxes in what I was always looking for.

### 5/5 — Катана Го

*2024-08-03*

Хз, топовая приблуда и приложение.

### 5/5 — Landscape Modus Please!!!!!

*2024-05-27*

Das Ding klingt wirklich gut und ist perfekt zu üben. Es bräuchte aber dringend den Landscape Modus - das ist doch heute Standard bei fast jeder App

### 5/5 — Love Katana GO

*2024-04-13, version 1.0.1*

This device is perfect. Software does need a little extra work. Hopefully they will continue to develop and improve the app.
