The Gmail mobile app is is an app developed by the googke mail services. This is the most used app for the emails and nowadays is highly recommended by every one specially if he or she is related to a professional designation. This app is not like the WhatsApp messenger but this is an email app where you can send the professional things or non professional things without sharing any personal information to the other end.
Well this is the best part of this application or we can say the email service.
This thing can only be understood by an example. In a WhatsApp if you will send a message to anyone then he will get many information about you like the mobile no., last seen and profile photos maybe but if you will send an email to any1 then it shares only your emailid and nothing more than that.
Now heading towards the feature and concept of the gmail mobile app as I have used it.
You can install the app from the app market of your mobile. Simply install it and then you will have to log in if you have a id of gmail otherwise you can create one and them log in.
Then another amazing feature comes in. In the homepage of the application you will find all the emails. When you will refresh the page then you will find that many folders will be created. Such as promotional, social etc. These folders get created automatically by the app so that you you can get an abstract that what the email is related to. So if you want then yoh can ignore such mails.
Then after that there are no. of folders like starred( shows the messages that you have marked important) , spam( show the spam messages) , outbox( shows pending ones) , draft( shows incomplete ones) .
So this ways the concept and features are of gmail mobile app amd has a great usability.
It doesn't occupy much space and data, You can turn off the mobile app's background data and it won't take any external data.
So I will highly recommend the app to the other users.
