### 1/5 — Connexion

*2025-12-09*

Impossible à connecter j’ai investi dans l adaptateur pour connecter à mon iPad 
Et il se passe rien 
Pas top 
L appli ne fonctionne pas

### 1/5 — Connexion impossible

*2025-11-05*

J’ai acheté ce B2four avec l’idée de pouvoir gérer mes effets sur mon téléphone, mais impossible de me connecter avec un simple câble USB3 - Lightning.
D’après le retour du service technique, il faut que j’achète en plus un adaptateur Apple, mais il ne m’ont pas donné la référence.
Je crois que je vais encore en avoir pour 50€ ( si j’ai fait le bon choix d’adaptateur ).
Je laisserai un autre avis si j’arrive à me connecter.

### 1/5 — No!

*2025-03-24*

No connection possible. It needs hours to download the initial effect content. Very disappointing at all

### 1/5 — Permanentely saying: no device detected. therefore not usable.

*2023-11-24*

The title says it all. I‘m very disappointed.

### 2/5 — Just paid for pedal. App should be free

*2026-06-17*

I’m a little surprised I have to pay another $1 after dropping $250 on the pedal

### 3/5 — Works fine but very limited capabilities

*2025-12-28*

The app lets you control the device from your phone, including editing patches. But it doesn’t let you back up and manage your patches, nor does it provide access to patches developed by anyone other than Zoom. Personally I don’t find it easier to edit patches on my phone than on the device, and given that the phone must be connected by a short USB cable it’s not practical for using on stage.

### 4/5 — Not free ??!!

*2025-01-21*

Too bad we have to pay for this app :(

### 4/5 — Must have device connected

*2023-04-04*

I had hoped to be able to get a little preview of what it looks like, what patches are available and what additional effects might be available (as pre-purchase research). However, without a device connected it doesn't do anything. Understandable, but it would be cool if they had an "Offline" mode to mock things up. I get why they don't though.

### 5/5 — 使いやすくなりました

*2025-12-23*

iPhone 16e にしたのでこのアプリを買ってみました。本体との接続はiPhoneに付いていたものUSB-C→ USB-Cを使いました。本体の電源はACアダプターから取りました。で、使い勝手はパッチファイルの移動が簡単に出来るのでライブで使う順に並べるのが簡単になりました。あと当たり前ですが、色んなエフェクターの調節が楽になりました。買って良かったです。
