Looking for app that will vibrate every 5 minutes when i talk on the phone

[Jimis12]

Hey i am looking to cut out my talk time when i am on the phone,

Therefor i am looking for an app that will help me understand when i talking of the phone with someone for more than 5 minutes.

The optimal app will be an app that send vibrate every 5 minutes when i am in a call.

Does someone know an app that can help me do that?
Thanks

Use a timer app.
There are many of them out there.

Something like Call Timer perhaps?

And there a few other apps that do a similar thing

Thank you appreciate the suggestion, I have galaxy S4 and it seems like this one is not supported there.

I did found some call timer apps like this one but they end the call while i only want reminder for the call time.
