Call Guard

By Cribasoft, LLC

Open iTunes to buy and download apps.


Got proximity sensor issues on your iPhone4? There's an app for that! Call Guard prevents accidental user input while on a phone call, putting an end to accidental hang-ups, mutes, speakerphones, etc. There is no other way to lock the screen while on a normal call, as the Lock button will End the call on OS 3.1 and later.

No more e-mails written by your cheek!
Once on a call, start Call Guard. The quickest way to do this after the first time is to double-press Home and fast-switch to it. Call Guard displays an attractive colorful screen with no interactive elements while on a call, thereby totally preventing accidentally pressing any numbers, hanging up a call, turning on speakerphone, muting the handset, or any other interaction that might be undesirable while on a call.

Call Guard does not do anything beyond provide a completely safe app to run to prevent accidental input. This is necessary because if it had features beyond that, they might accidentally be triggered while on a call (and thus not paying attention to the touches on the screen).

The only solution that really works!
Call Guard works better than launching other apps such as Calculator, because the "Return to Call" overlay that appears at the top of the screen during a call is also hidden by Call Guard. With other methods, it is still very possible to tap "return to call" and then you are back at square one.

Totally fail-safe!
When you want to interact with the touch screen again, simply quit Call Guard by pressing the Home button on your device.

What's New in Version 1.2

Added a Setting (see Settings app on your device) to show a darker version of the backdrop while on a call. This reduces "face glow" when using the phone at night. The touches will still be easily visible.

Does what it says.. Sanity saver

I have had moments of giving up on this phone I love so much. Although I am still considering trading this in for replacement.. I spent to much on this iphone4 to go through this and I heard that not all iphone users have this sensitivity issue.. The majority do.. But a select few ..dont. So ..Until then I will use this app. It can be a bit irritating .. If you are on a call that requires you to use keyboard.. Then something else.. As you go back and forth.. But at least you are doing it yourself .. And it's not your phone doing something random .. Out of your control. I have not once had a speaker/ mute/ dropped call .. Or most important.. A call made by my face , while talking to another while using this. so im happy for now.
And Apple? They NEED to fix this.. Or pay for this App until they do. Get it.. You'll be happy you did. Make your call.. Go to app .. Click on it .. Enjoy your call. The best thing is.. It will let you know how many times you avoided a mishap.. My last call saved me 63 times!!! That's just crazy!!


I told all my friends that the iPhone was indeed NOT the perfect phone and I couldn't wait for my contract to expire so I could get a different kind of phone. Apple and AT&T acted completely oblivious like no one else mentioned it. I was FURIOUS when Apple didn't address it with other problems, especially considering I don't have any service issues!!! UGH!!! I was paralyzed talking on my phone as if I moved an inch, I'd hit mute, Facetime, contacts, etc. I even managed to add another call to mine before, WOW! So when I searched for an App to fix it, and found Call Guard, I was amazed. This app is the ONLY reason that I am keeping my iPhone. In addition, I have told all my Facebook friends about it, many whom downloaded it immediately!!! There's one review here that says, "Stupid". They must work for Apple. THANKS Call Guard!

A MUST HAVE for hearing aid users!!!!!

My 89 year old grandfather love's his iPhone. But a single conversation with him consists of multiple accidental hang ups & call backs. All due to his hearing aid conflicting with the proximity sensor. I discovered this is a huge issue for the hearing impaired community & Apple while I was searching for something to help my grandfather. Up until I stumbled across this App my search had been unsuccessful. Now after installing & showing him how to use it on his phone, I think we've found it!! So my sincere thanks to the creator of this App!!! You've helped my family more than you know :).
