### 1/5 — Я ущемился

*2025-02-16*

Сегодня я не посрал и поэтому недоволен, а так приложение хорошее

### 5/5 — Tres bien

*2022-10-28*

Très utile. Merci pour les travaux.

### 4/5 — Oops!

*2021-03-17*

The xy calc has stopped working. As a lighting console programmer, this was one of the most useful tools for me. It’s gone now. Opens to a blank screen. 
Bummer...
This is a great app but that bug has killed it for me.

### 4/5 — Amazing and helpful

*2020-12-15*

This is superb to me as a cinematographer, it just helps me to pickup the light before I even have it in my hands.
I really hope you guys add the new Orbiter fixture so I understand more about this new piece.

### 5/5 — Super

*2017-07-21, version 4.0*

Sieht sehr gut aus.

### 1/5 — Awful update

*2017-07-18*

The previous version was much better.

### 1/5 — nicht mehr iPhone 5 kompatibel

*2017-03-12, version 3.0*

Tolle App, echt praktisch. Seit einem Update ist sie aber leider nicht mehr mit dem iPhone 5 kompatibel. Ich wüsste nicht, warum diese App mehr Kapazitäten bräuchte.

### 1/5 — War mal sehr praktisch.

*2016-10-28, version 3.0*

Die letzte Version lässt sich leider nicht auf iPads der 3.Generation updaten. Wird jedoch als Update im Appstore angezeigt.
Schade und etwas nervig...

### 5/5 — iPad 4

*2016-10-02*

I can't use it on my iPad 4 now. Why?

### 4/5 — Good but..

*2014-11-26*

This is missing a few things. Such as the barn door/speed ring sizes. It is different than the scrim sizes in the M-series. Also it could use the specs on the various ballast dimensions, weight, lamps they support, etc. Otherwise pretty handy app.
