From the “Block” section, Truecaller unravels two options, the “View Spam List” shows the number and contact info of the most common spammers on your list while the “Block Settings” section unveils the option to block telemarketers and nuisance calls.

The floating “Bubble” icon allows you to manually choose what to block.

Always remember that 3G or Wi-Fi is required for Truecaller Caller ID to work and Operator charges may apply.

DU Caller Review

DU Caller is another competitive caller ID app for android. The app helps you to identify unknown number and block unwanted calls.

The app been multi-lingual, brings the largest phone number database where you can recruit the numbers of different caliber of peoples.

While this feature might seem intriguing, it’s however limited to Samsung Galaxy device. The call Recorder feature on DU Caller provides automatic and manual call recording functions and you can manage and set password protection to keep your recordings secure. In summary the call recorder integrated in DU Caller is the unique feature that Truecaller doesn’t possess.

1. Caller ID

The “Private Contacts” is one of the cool features offered by DU Caller. It’s just like encryption, the Private contacts main function is to hide a list of contacts that you don’t want anyone to know you’ve been talking to. Thus DU Caller ensures that the numbers added into the Private Contacts option does not show up in the call history or anywhere in the phone. To view your call history again, you’ve to unlock the Private Contacts with a pattern lock.

6. User Interface

DU Caller brings a pretty intuitive user Interface, the app has been coded clean and from the user profile, you’re provided with varieties of options to dive into. However one thing i noticed is that the “Life Assistant” has been removed from the update, this option back then provides a directory of the most commonly used numbers for various services around you. Thus you can get numbers from shopping destinations such as Flipkart and Amazon. Th DU Caller “Settings” unravels options that you can tinker with, to get things going.

Is DU Caller Save?

DU Caller is 100℅ save, the app is very simple to use and the startup process runs you through a brief introductions. Unlike Truecaller, DU Caller doesn’t require your phone number during the initial startup, but you might want to give them this info when you’re setting up your Caller ID. Also DU Caller doesn’t ask for E-mail address which makes it more secure and convenient.

Final Verdict

Both the Truecaller and DU Caller android app are good. The apps seems to perform the same function but the DU Caller provides advanced features which is however “Limited”. When you need to record a phone call and save them as evidence, then DU Caller comes into the picture. Apart from this, Truecaller and DU Caller will immediately give you a detailed caller ID for an unknown number and when you don’t know where to find your old friends, you can use Truecaller or DU Caller to search for their numbers. The screenshot below unveils both the Truecaller and DU Caller in action.

Upon receiving an incoming call from one of my country’s operators which i definitely knew was a Spam Call (a way to promote their offers), Truecaller immediately branded it a “Spam Call” and provides an option to “Block” it. While on the other hand DU Caller left me to figure out if the call is a Spam Call or not (intuition). Overall i can’t actually tell you that Truecaller is better than DU Caller (vice versa) but if perhaps you’re to ask me to make a choice, then I’ll definitely go for “Truecaller”. If you’re using a Samsung Galaxy device, then the voice recorder integrated into DU Caller should be enough reason for you to choose it and moreover the “Private Contact” feature in DU Caller provides a powerful encryption for your call history.
