## Most critical reviews (10 lowest-rated)

### 1/5 — ?

*2024-12-11*

NiSi makes great filters, but not this app

### 1/5 — NBG

*2024-10-10, version 1.1.4*

Fails to work. Appears to need a Bluetooth connection to camera to work - but doesn’t . My camera connects to other Bluetooth apps OK

### 1/5 — Keine Funktion!

*2023-11-09, version 1.1.4*

Leider funktioniert das NiSi BRC Gerät nicht. Die APP muss ein Update machen.

### 1/5 — Funktioniert nicht

*2022-10-14, version 1.1.4*

Sollte zusammen mit den NiSi ND Calculator (BT-HW) funktionieren. Das Gerät wird aber nicht erkannt. HW unbrauchbar, App unbrauchbar

### 1/5 — Limited, forgets device

*2021-10-01*

I was excited to purchase the blue tooth shutter controller and use it with this app. Turns out this app is going to kill the controller. It constantly forgets the device and becomes a pain to re ad it each time I want to use it. The app is very limited. I really hope that NiSi re writes this app and ads some cool functions like intervalometer functionality.

### 1/5 — Doesn’t work

*2019-01-05, version 1.0*

See above

### 1/5 — Crashes on startup

*2018-12-05*

IPhone Xs

### 4/5 — Great app but…

*2021-07-27*

Trying out the exposure calculator it is simple and intuitive to use but it would be great if there was a dark mode or a red light mode so it can be used for Astrophotography…
Developers might be something to add?

### 5/5 — 最高

*2025-09-12, version 1.1.4*

手放せません。

### 5/5 — シンプルでとても使いやすい

*2023-01-08, version 1.1.4*

これまでNDフィルター使用時の露出補正値算定に指折り数えて補正段数からシャッタースピードを割り出したり、スマホに入れた換算表を使用していましたが、このアプリが断然便利で速くて間違いも起こりません。NDの表示単位やシャッタースピードの刻みも選べます。自社製品用に特化しないNDフィルター全般に使える一般的なアプリを提供するNISIという会社の良心を感じます。
