The offline availability of the caller ID application.

Similar to Truecaller, once a number has been identified, you don’t really need an internet connection to recognize it the next time the user receives a call from it. Do you?

#8. Search Number

Thanks to the Search bar integrated as a part of Truecaller interface, users can search for the numbers quickly. All you need to do is enter the number as Search field in the dedicated bar and have the information at the fingertips.

Not only this, but users can also enter the address and names of people to access the publicly- available information.

#9. Instant Messaging

In addition to in-app messaging and calling features, Truecaller also lets you access great Instant messaging functionality. That is, users can connect with fellow app users for free. Woohoo…

Continuing with the mainstays, users can auto-switch between SMS and chat, keeping conversations at one place.

So what do they need? The same feature in your app, of course…

#10. Smart Notifications

Well, ever requested an OTP from Bank? Of course, we all have. And what does the message contain? Loads of information even though all we are concerned with is, the NUMBER.

But Truecaller’s smart notification feature is here to the rescue. Applying intelligent methodology, it lets you filter the information exactly how you need it. It presents before you instant and glanceable notification for transactions and bill reminders.

Thus, you can have a comprehensive system implemented here that is capable of scanning through the incoming messages locally on the phone by the time you pick it up to check. Having this feature will let you offer a great deal of experience to the user by highlighting relevant information like OTP numbers, transaction amounts, or payment alerts.

#11. Delete Profile

Okay, it does happen at times that we wish to discontinue our profile on specific platforms for some time or maybe more. While it is understandable to get disheartened seeing users leaving, there’s absolutely no point in not having them aboard just because they feel they won’t have a chance of leaving.

Thus, something like Truecaller, you need to add this feature while aiming to develop a caller ID app like Truecaller. Make sure you do not make the process lengthy for the users, and rather give them liberty to delete the profile in a few clicks.
