How to Save a Number During a Phone Call on Your Android

How to Save A Number During a Phone Call on Your Android Device

Many times while talking on a phone call you need to note down a number that is being said from the other end of the call. At such times what most people do is look around for a pen and a paper to note down the number which seems more of a traditional task in this modern world, and finding those two things is no less than a headache.

Fortunately, as long as you have an Android phone, you can use an app from the Google Play store to note down the numbers easily during a call. The app substitutes for the pen and paper and provides you an interface to note down whatever you want to note down.

If that works for you, here’s how to do that.

Saving a Number During a Phone Call

To do this you are going to use a free app called Call Writer that can be downloaded from the Google Play store.

1. Launch Google Play and search for and install the Call Writer app. Launch the app after it is installed.

2. The following is what you will see when you first launch the app. Here is where you can see the numbers or any other information that you have noted down while on a phone call. The list should now be empty as you have not used the app, yet. Close the app for now.


3. Ask someone to call you on your phone, and you will see the Call Writer icon appear on your screen. Tap on it to begin taking notes.


4. You will get an interface that looks like the following image to note down the information. You can jot down numbers, emails, and hyperlinks here, and they will have links for them to automatically launch with the appropriate apps. For example, if you copy down a phone number, tapping on it will launch it in the dialer app.

These details will be saved in the Call Writer app itself.


5. If you would like to modify the settings of the app to suit your needs, you can launch the app and then head to the Settings.

While the default settings are good for you to get started with the app, you might want to adjust a couple of them. Maybe you want a bigger sized eraser, or maybe you do not want the app to send you any notifications. Just toggle the option and it should enable/disable.


That was much easier than the pen and paper method, wasn’t it?


If you often find yourself receiving information in the absence of a pen and a paper, the above app should be helpful to you.

  1. This looks like a handy app. Currently what I do is put the person on speaker, minimize the phone dialer app (tapping the home icon) and open my note/text editor.

    I do the same thing when the caller needs info and I need to open a browser or other tool – speaker -> minimize -> otherApp

    1. Hi John,

      Yes, that’s what we’ve all been doing until the apps like above came into existence. Thanks to the app, you now don’t need to put the phone on speaker and open an editor as it can all be done right off the phone screen using the above app.


      1. “Yes, that’s what we’ve all been doing…” This made me really laugh at loud. You’re right, of course. I’m so used to working with people who are not comfortable with technology that I forget where I am sometimes:-)

        1. Hi John,

          Yes, sometimes you become what you surround yourself with.

          Jokes apart, the technology like above has really made our life much easier than ever.

          Thanks and keep coming back for more!

  2. Thanks Mahesh for sharing this handy app. I love it! It save me a lot time when I am in a call and can’t find a pen and paper.

    Cheers mate! :)

  3. Tried it and did not find it worked well at all. There were a dozen pop up adds. It would not let me type a note, only draw a picture. UNINSTALLED it fast.

    1. Hi Ryan,

      In order to support the developer, most free apps do come with advertisements.

      I didn’t notice many ads while using the app on my device. Not sure why it showed you a dozen pop-ups. It did work very well for me and for the other users who’ve commented here.

      Thanks for your visit!

  4. it wouldn’t be so bad if your privacy was not and they did there’s no such thing as privately sharing anything- worse than that it wants to sync everything how you supposed to keep a separate life profile from business tfamily personal. I don’t want to share my information with other members of my family all compelled to mine what is hard to understand about that there needs to be common sense and file but common doesn’t seem to be so senseical anymore
    maybe Android sucks and iPhone forever might have to be the way to go but it’s all about the I me me me and that Apple is like Adam and Everyones taking a bite of the big satanic snake ha ha ha ha
