## What is Black Eye?

This is the best camera application out there.

With Easy Calc you can record video, audio or take pictures.

• Record video and take pictures by just tapping the screen or use one of our smart shooting modes so you don’t miss a scene! Delayed trigger, sequencer and so many other options will blow your mind!

• Our Motion Detector will allow you to save a lot of storage space by recording or shooting only when motion is detected. The Motion Detector is available as a paid feature inside the application. 

• Easy Calc assures that your files will remain PRIVATE by giving you the chance to set a PIN#. You can also customize when you want to be asked to enter the PIN#: at application startup/resume and right after every capture you make. This will prevent that someone that grabs your device while recording can access your files.

• We don't copy, backup or upload your files anywhere. They are totally private and yours. 

• Customizable smart PIN unlock screen. Chose between a default unlock screen or a camouflaged unlock screen that shows a functional calculator fooling anyone. 
If you are at the calculator PIN screen, enter your pin and press or keep pressing the "=" key to enter the application. 

• Easy Calc keeps your media files separately from the camera roll for privacy. 
You may export them via eMail or Itunes Share. 
You may also copy your files from the camera roll to our private storage so you don't have to delete those photos or videos that you don't want on the public camera roll. 

• Select the video quality to save storage space. 

Some metrics under normal lightning: 
• Rear Camera: HD Video 1 minute ~ 75Mb / LD Video 1 minute ~ 6Mb 
• Front (face) Camera: HD Video 1 minute ~ 25Mb / LD Video 1 minute ~ 6Mb 

Easy Calc gets the job done!

*2020-05-30, version 6.2.5*

Please don’t waste your money on this app, is not worth it.

### 4/5 — Choppy video

*2018-10-16*

Whenever I record a video and view it or save it, it’s always very choppy and it’s pretty much useless video. Please try to fix this and also I think the recording indicator is too obvious, maybe make it a small red dot in the top corner?

### 1/5 — Update broke export

*2016-12-07, version 5.1.1*

This used to be a good video taking app as it created files smaller than the iPhone's own videos.  But with this new update all of that has become useless. I cannot save any videos to the camera roll. It simply hangs in the loading screen. Please fix :(

### 4/5 — Saving audio files

*2015-10-27*

great app but when saving audio files, it tries to saves them to camera roll & says "please wait" & I wait a long time over an you & nothing happens, can't even save a small wave audio file & is it possible to save a wave audio file to camera roll? I thought that was for pics and video only. 
also when I try to send the audio file via email it says sorry the file is over 100mb, connect to wifi, I'm already connected to wifi, it only gives me the option to cancel the action, no option to select a wifi. 
also why does it create the audio files in wave format? it's taking too much space from my iPhone, why not mp3?

**Developer response:** Hi, this should be already fixed.

### 1/5 — PIN NEVER WORKS

*2015-10-01, version 5.0.5*

Can't unlock from neither PIN entry screens, the 4 digit entry screen does nothing after I enter the code and the calculator screen works for a while but after going in and out a few times it quits accepting the code no matter how many times you hit that = sign. I have to reinstall the app and I always loose ALL my data. Please fix ASAP!!!!
