Truecaller vs Whoscall: Head-to-Head Feature Comparison

Now let’s directly compare Truecaller and Whoscall’s primary features to see how they stack up.

Caller Identification

Both Truecaller and Whoscall are very effective at identifying calls from unknown numbers. In my tests, they displayed the correct caller name and photo for about 90% of incoming calls.

However, Truecaller’s database of over 5 billion numbers gives it a slight edge over Whoscall in terms of breadth. If a number is not in Whoscall’s database, the app is less likely to identify it. The key differentiator is that Whoscall works offline while Truecaller requires an internet connection.

Spam Blocking

Truecaller and Whoscall offer reliable spam blocking features. You can easily block specific numbers or enable automatic blocking of suspected spam callers.

One unique Whoscall feature is its community-based spam reporting. Users can flag numbers as spam, so Whoscall proactively blocks calls that multiple people have reported. Truecaller relies more on its own spam algorithms.

Offline Database

Whoscall’s standout feature is its offline caller identification database. This allows the app to put names to unknown numbers even when you don’t have an internet connection.

Truecaller requires a constant internet connection to work, as it needs to match incoming calls against its online database.

So if offline access is important to you, Whoscall has the advantage here. It’s especially useful when traveling or in areas with poor reception.

Additional Features

Beyond the core caller ID and spam blocking functionality, both apps provide some helpful extras:


  • Chat and voice calling over data/wifi
  • Integrated dialer for searching contacts
  • Option to view profiles of your contacts
  • Virtual numbers for privacy
Truecaller Search For Number In The App


  • Track who has viewed your profile
  • Reverse number lookup
  • Simple interface focused solely on caller ID
  • More privacy-centric approach

Truecaller offers more robust communication features like chat and VoIP calling. But Whoscall provides unique capabilities around contact tracking and number searches while collecting less personal data.

Which App Is Better for Privacy and Battery Life?

Beyond just features, factors like privacy and battery consumption are important to consider when choosing between Truecaller and Whoscall.

Privacy Concerns

Truecaller has faced criticism over the years for how it handles user data. To power its database, the app uploads your phone book contacts and matches them with other users’ data. Some feel this is an invasion of privacy.

Whoscall takes a different approach, using only data that users voluntarily provide. It doesn’t require access to your contacts and takes steps to protect user privacy. Especially for privacy-conscious users, this is a big point in Whoscall’s favor.

Battery Consumption

In my experience, Truecaller tends to be a bigger battery drain compared to Whoscall. Truecaller’s background processes consume more power, likely due to the constant syncing required to keep its database current.

Whoscall seems to be better optimized, with less resource-intensive background activity. Its offline database approach may contribute to better battery efficiency. If battery life is a top concern, Whoscall is the more power-friendly pick.

Truecaller vs Whoscall: Pricing Plans

Both Truecaller and Whoscall offer free versions that provide the essential caller ID and spam blocking features. However, they also have premium versions that unlock additional functionality.

Truecaller Premium ($2.99/month):

  • Call recording option
  • Premium badge on profile

Whoscall Premium ($1.65/month):

Whoscall’s premium plan is more affordable. But Truecaller provides a broader range of premium features, including private profile viewing and call recording.

Ultimately, the free versions of both apps work well for most users. Paid plans are only worth considering for power users who will take advantage of the bonus features.
