The possibility of setting a personalized and different ringtone for each friend or contact of the mobile phone has existed for several years, since Nokia Symbian and perhaps even earlier. This way you can recognize who is calling before you even look at the screen and then decide whether to answer or ignore the call.
However, if you keep your mobile phone silent and without a ringtone, it is impossible to know who is calling from the vibration, unless you have an Android smartphone.
One of the limitations of keeping the phone silent is that you never know who is calling so you can hear the phone vibrate in your pocket and you are forced to look at the screen to know who is looking for us.
With the free application Good Vibrations for Android, you can create personalized vibrations to be assigned to the contacts so that you can identify them even without looking at the phone and without needing it to ring.
The application shows a short tutorial the first time you start it.
From the main screen you can start creating your own vibration patterns .
Then tap the red record button and then swipe your finger over the vibration circle at the top recording the vibration.
Whenever you touch that circle, your cell phone vibrates, so you can easily create a vibration rhythm of any type, with longer or shorter intervals.
After composing a vibration, you can "feel it" by pressing the Play button to see how it came about.
If confirmed, you can open the contacts directory by pressing the little man at the bottom and choose to assign that rhythm of vibrations .
You can assign a vibration pattern to groups of contacts, for example work, friends and family or assign different vibrations to the most important contacts on the list, for example, your mom, boss or children.
All contacts that have been assigned a custom vibration show a specific icon.
Assigning different vibration patterns for the various contacts in the address book on Android is a useful and rather curious feature that can help identify the caller in situations where it is not possible to take out the phone, for example in the classroom, at the cinema, in a meeting.
