How many times have you received a call from some unknown number, just to discover that it’s not that person you gave your number to, yet a promotional call, or spam? A few people don’t even bother answering calls from unknown numbers for this very reason. That is exactly where DU Caller (Free) comes into play. DU Caller is, at it is core, a caller ID app. Accessible on Android, the application ensures that you generally know who’s calling you, and furthermore whether or not you ought to answer. We decided to give DU Caller a try, and share our two cents with you.

User Interface and User Experience

While some may argue that the interface is secondary to the function (and I kind of agree), it still is a very important part of the app. Also, that is where DU Caller nails it. The interface is clean, and intuitive. The selection of colors is incredible, white and blue. It follows Google’s Material Design principles, and follows them perfectly, might I include.

The hamburger menu slides right in with a quick swipe from the left, and shows all of the features that are accessible in the app. You get “Settings” on the top, followed by various different features, that I’ll go into detail later. One thing that I would like to point out, is that I’m very happy, that the app provides an option for “Feedback”, as well. Not numerous apps do that, and it’s good to see an app that does. If there is one thing that I wish they changed, it’s the counter on the top of the home page, which can be a bit distracting. Aside from that, this app is incredible, as far as UI is concerned.

Features

DU Caller offers various features; it’s not just a caller ID app. I mean, they obviously state that it’s a recorder, as well, among numerous different things. However, if you read the description of the app, the recording feature is only available on “several Samsung devices“.Tragically, we don’t have a Samsung gadget, here, so I could not test that particular feature out. I’m simply going to assume that it works, however, because the rest of the app works truly well.

• Caller ID

Starting off with the Caller ID function, the application was effectively able to identify various spam calls from the call history, and was able to correctly recognize my phone number, which (I checked) was not saved in the contacts of the test gadget. You can simply tap on the “shield” to scan your call history for unknown numbers, that DU Caller can attempt and recognize for you.

Swiping from the right, gets us to the Search page, where we can search for numbers that we have to find the names to. Now, they say they have a big database, and they probably do, at least for spam callers. I found that while DU Caller was great at identifying spam calls, it didn’t perceive most of the phone numbers that I searched for. Phone numbers of real, actual people,that I know. That said, it did recognize some of them.

Another swipe from the right, and we are at the screen where we can see everyone we have blocked, and we can even include new numbers to the list.

•  Life Assistant

The Life Assistant in DU Caller is essentially a directory of the most commonly used phone numbers for numerous services around you. So, you get phone numbers for shopping destinations such as Flipkart, and Amazon; alongside phone numbers to telecom operators.

You will also get the contact numbers for travel agencies, emergency helplines, healthcare, financial services, and significantly more. Essentially, the Life Assistant is there to ensure that if you ever require a phone number to any service around you, you can effortlessly get it.

• Private Contacts

One of the truly cool features provided by DU Caller, is Private Contacts. This is exactly what it sounds like, a list of contacts that you don’t need anyone to know you’ve been talking to. DU Caller makes sure that the numbers you include into Private Contacts don’t display in the call history, anyplace in the phone.

The only method to view the call history for these numbers is by utilizing the DU Caller app, unlocking the Private Contacts with a pattern lock, and then you can perceive the call history for those contacts. The reason my number wasn’t visible in the screenshot where I showed you all the recognized numbers, is because I tested my number with the Private Contacts.

• Settings

The Settings page for the application is extremely simple. There are two sub-headings, namely “Block”, and “Pop up dialog”. Both of these permit you to change how the application carries on the phone. Under the “Block” sub-heading, you can make the application automatically block common spammers, international numbers, and more.

In the pop-up dialog, you can set up when you want the DU Caller pop-up to be showed. By default, the pop-up is displayed for each call that comes in to your phone. The great thing about this, is that the pop-up is not obtrusive, and wouldn’t truly get in your way, so it may be a great idea to keep it to default.

Know Who’s Calling You with DU Caller

DU Caller is a good app. One which you can use to identify spam calls, and even to block them directly, without having to go through the trouble of doing anything. You can simply toggle the setting for “Block Common Spammers”, and the most common numbers that are reported as spam, will automatically be blocked from your device. The private contacts option is also good, especially if you correspond with people that you’d rather others didn’t find out about.
