### 1/5 — Ne fonctionne pas !!

*2022-02-24, version 1.50*

J’ai acheté cette appli pour rien car elle ne fonctionne pas avec mon iPhone 6. Je souhaite me faire rembourser, merci !

### 4/5 — Problème depuis mise à jour

*2020-03-03, version 1.50*

Depuis que j’ai téléchargé la nouvelle mise à jour l’application de fonctionne plus. Dommage elle était très pratique.
Cordialement

### 4/5 — Love it... A library would make it perfect!

*2012-12-07, version 1.0*

I love this app and use it all the time. The only thing I'd love to se to put this app over the top would be a library where I could store all my lenses with their related zoom ranges. Maybe even also a library for my screen setups. I find myself always having to look up my various lens specs. A library would be fantastic!

### 5/5 — Does what says on the tin!

*2018-04-13*

Clean and uncluttered interface, focused just on what you need for lens throw ratios, screen sizes, distances.

I should point out that all calculations assume a flat screen with a straight-on projector.

### 5/5 — Great tool and soon to have 16:10

*2016-05-16, version 1.3*

I have used this application multiple times to calculate lens throw distances based on screen size and to calculate screen size possibilities based on distance. It works very well. It saves a lot of time and guessing for those of us that have a math disability. An invaluable tool for projection calculations.

### 5/5 — Simple et efficace

*2012-08-06, version 1.0*

Une application utile et bien conçue!

### 5/5 — Exactly what I was looking for

*2010-09-26, version 0*

Works great, can get focal distances when setting up a new projector, verify screen sizes when ordering a new screen, determine screen size limitations with various lens ratios, both fixed and zoom. A great tool for an AV installer of projection equipment.

### 5/5 — Do the work

*2010-08-20, version 0*

Simple, usefull, cheap

App is easy to use, any kind of measures can be used (meters, foot, cm (...) has long the measures you enter are all the same.
