### 3/5 — AUv3対応希望

*2023-05-08*

とても使いやすく気に入っているのですが、AUv3に対応していないため今後が不安です。
なんとかAUv3に対応していただきたい！

### 2/5 — Already bought all iap’s for the IPad

*2023-05-06*

I’m definitely not buying everything twice just to use what I already paid for on my IPad just to be able to use them on my IPhone ….never gonna happen ….never , and none of Positive Grids apps are auv3 compatible so that shows how completely out of touch they are. I’ve been buying all their apps and in app purchases for years but I will never buy another thing from them until they have auv3 support.

### 1/5 — Robotic Crackling on iOS 16.2

*2023-01-12, version 2.1.14*

Must be an issue with an update but making review one star until resolved.

### 1/5 — Only works with the built in iPhone mic, pretty useless with a guitar

*2022-12-31*

At least you have tonebridge

### 1/5 — Не подгружается в Гараж Бэнде

*2022-11-05*

Раньше работало ок, теперь падает в ошибку «Приложение временно недоступно». 11 Pro, 16.1

### 1/5 — Stürzt ab

*2022-10-26*

Stürzt direkt ab….. iPhone 13 ios 16.1… ab und zu geht es dann kommt nur i.ein ufo sound…

### 1/5 — Все плохо

*2022-09-24*

Не работает на iPhone XS ios 16.

### 1/5 — Money makes the world go around …

*2022-04-20*

I own BIAS Amp v1&2, BIAS FX v1&2 Elite Versions(!) on Mac OS including Hendrix and all cabinets. The same for Ipad and for Spark! So I did pay A LOT of money to Positive Grid.
A few days ago I bought an iphone 13 mainly because of musical reasons and hey … Positive Grid wants me to pay for the forth time even if ipad & iphone run the same OS. Okay, they need to trim the UI a little bit. Other companies can do that for free. 
Why don‘t you create versions for every single week day? You could earn 7 times as much!
I am shocked!

### 1/5 — No voice over support

*2022-03-15, version 2.1.13*

Hello. 
This seems like a very decent app. However I am a visually impaired person. Would you consider in a future making it voiceover accessible? 
Thank you. 
Dmitry

### 1/5 — It was good! But lack of updates…

*2022-01-31*

Positive grid does not care any longer for support on “older” apps. It’s been more than 10 months since the last update. The app keeps freezing and not loading the online library… It’s a shame… The company does not respect their costumers. I’m a owner of a Bias Amp Mini and I will think twice to purchase another product from Positive Grid.

### 2/5 — ダメポ所たくさん

*2022-01-30*

bias愛好家としては、アプリは全てダメ。　　iPad課金したのにiPhone版は別(ampもfxも) 　　アプリ内課金でなくサイト経由でも買えるが、知らないと損する可能性あるのに説明なし(ある？)　　そもそも、高音質なインタフェース使わないから、いい音出せない。　かといって良いインターフェース使うならdtmでいいし、モバイルじゃなくなる。　　　　bias登場当時は他より抜きん出てたが、販売ばかり必死になり始めてから凄くダメになった。　とても残念。

### 1/5 — Spam alert !

### 1/5 — いや使えん

*2021-10-06*

遅延で　気持ち悪くなる
使えませんな

### 1/5 — Свистит

*2021-03-31*

При включении приложения начинается свист в наушниках либо в колонках. Играть на гитаре не возможно через joyo I plug, I rig. Разъясните причину. Раньше работало. Снимает сигнал с встроенного микрофона телефона

### 1/5 — Outdated

*2024-12-28*

There is a bug on interface. Its screen doesn’t fitting correctly with iPhone 15/16 series’ screen. 

Some buttons are above other buttons on different sessions. The right side of ToneCloud session is not being used totally when I search for amps created by community. There should be 3 columns instead 2 to present the community presets.

The right side on my profile session is not adapting correctly with my screen. Even if I turn to the side that doesn't have Dynamic Island, some infos doesn’t appears totally.

### 1/5 — Not working.

*2024-12-26*

Ever since I downloaded and bought Bias Fx 2 pro package software I wanted to get creative with the amp building I downloaded this add-on for it and it is completely messed up and does not work. All it does is give me an annoying feedback sound as soon as I turn a knob or try to do anything. I'm using the Irig2 which has no problem when I load up Bias fx2 and works perfectly. I hope this gets updated which probably won't but hopefully it does.

### 1/5 — Used to be amazing. Completely broken now.

*2024-11-03*

The app just simply refuses to work. The output is just emitting a really annoying static noise. At best if you unplug your gear and plug it back in, you hear your guitar clean, but with an undercurrent of static. You know, for flavor. Oh by the way, this doesn’t change no matter what amp you select. 

I tried uninstalling/reinstalling and same thing. Nothing fixes it. Been like this for years now. Not like they care, they already have your money. If you’re looking for a good mobile amp, look elsewhere.

### 1/5 — Completely broken

*2024-08-30*

I used to use this to record on GarageBand on my old iPhone all the time and it had the best sound quality my iRig2 could handle. I got a new phone and this app just doesn’t work anymore. None of the presets do anything and the base clean amp has what I can only describe as a horrible static feedback every time I strum. No matter what I do in the settings in the app and on the iRig2, it will not go away. The only setting in the app that seems to do anything just makes the static worse. Even better, I tried downloading biasfx2 to see if it would fix anything and an error keeps popping up saying I can’t download it. I’m completely disappointed because I used to really enjoy using this app to record music. If anyone is trying to find a decent plug in app, just stick to Tonebridge.

### 1/5 — Complete Waste of Time

*2024-01-02*

I used to use bias amp all the time it’s very useful sounds get and is honestly a good learning tool when you can recreate the tones you hear other people use when trying to train your ear, but one day I just got on and it kept closing out the app eventually I deleted it and redownloaded it and everytime I open it nothing will work I can select Amps and effects but nothing goes through it’s just a broken weak signal whilst bias FX 2 works fine I just wish it would’ve continued to work the way it used to.

### 1/5 — No Apple Silicon

*2023-10-05*

Pls make Bias products work natively on Mac Apple Silicon. M1 is around the corner for 3 years already...

### 1/5 — No AUV3, no inter-app audio

*2023-09-07, version 2.1.15*

Sure it says it has inter-app audio. Didn’t work with Cubasis 3 or Garageband. Doesn’t even load in GB, claiming it’s “unavailable.” So now I’m not convinced it would work probably even if it did have AUV3 support, which for some reason it doesn’t in 2023.

### 1/5 — iOS 16.5.1, iOS 16.6 distorted feedback

*2023-07-29, version 2.1.15*

On my one device that has iOS 16.5 I have no issues with the app, but on my other iOS 16.5.1 and iOS 16.6 devices the audio comes out with this digital distorted with some feedback sometimes. It's also affecting ampkit+ so I assume it just needs an update since the latest OS version broke something on these apps.

### 1/5 — A festival of BUGS

*2023-06-30*

Crashes on connection to hardware. Really boring.

### 1/5 — 即落ちボンバー

*2023-06-05*

実機にBluetoothを繋げたくて開こうとするが
即落ち。
運営さん、OS対応のアップデートしてください。外からの音が取り込みたいのに取り込めません。

### 5/5 — Awesome thanks

*2025-02-01*

Input output to be a little hot, but it’s got incredible sounds it works same work really good and I hope the future this gets better thanks

### 5/5 — All you need

*2024-12-22*

Reverb is included and the sounds you can get from this app are just awesome. From clean to metal. Everything in a pretty box.

### 5/5 — Problemas com o JamUp Pro e Bias AMP 2

*2024-05-01*

Estou usando um IPhone 11, com a última versão do IOS, com o primeiro Irig lançado e adaptador Lightning.
Mas só está saindo o som da guitarra limpa com algum ruído, alterno entre os preset e nada muda.
Me ajudem!

### 5/5 — 手軽

*2023-01-17*

本格的に使うのは難しいと思いますが、ガチガチの録音やらない人間からしたら十分すぎるアプリです。音も十分だし、いじれる幅も広い。

### 5/5 — Nice

*2021-10-07*

Great app. Have issue when opening it goes to store. When try to push back. App locks up. I have purchased. I have to delete app then reinstall.  Had to do this 3 times.

### 5/5 — Great app

*2021-05-01*

I think this has the best marshall models ever! The cabinet emulation also sounds very realistic. Love it!

### 5/5 — Great amps

*2020-09-24, version 2.1.11*

These are great sounding amp sims. They can be modded like a real amp. I use them live through a PA and record direct to console. Cliff

### 5/5 — 기기 차이로 구매한 상품을 사용하지 못하고 있습니다.

*2020-09-19*

저는 예전에 bias amp 2.0을 아이패드로 구매했습니다. 그런데 아이폰에서 구매했던 기능을 사용하려고 했는데 그러기 위해서는 아이폰 버전 애플리케이션으로 같은 상품을 한번 더 구매해야 하더라고요. 아마도 아이패드 애플리케이션과 아이폰 애플리케이션을 나누어서 다운로드 하도록 해두어서 그런 것 같은데요, 이 점이 의도되어있던 부분이 아니라면 제 아이폰에서도 구매한 상품을 똑같이 사용할 수 있도록 해주셨으면 합니다.

### 5/5 — Best I’ve tried

*2020-07-19*

I was very surprised when I first used this app, I thought it was going to be one of those usual run of the mill apps but no!! It is so easy to use and the amount of free content means you can get what you need straight away! 
It’s also fun to use, changing the amp colours and knobs and even changing the name too, I have recommended this to loads of people to use.

### 5/5 — It needs some improvements in the iphone version

*2020-07-14*

I haven't any complain about the sound quality, but I think you should include a impulse response loader module. In fact there is one in Bias FX 2 which I own, but it would be so much easier to have this module in Bias Amp 2.
