Truecaller has long been the go-to app for identifying unknown callers and blocking spam calls. But with increasing concerns over data privacy and battery drain, many are seeking reliable Truecaller alternatives in 2024.

As a tech journalist testing dozens of apps, I’ve curated this list of the 10 best free caller ID and spam blocking apps for Android and iPhone. These Truecaller alternatives provide robust features without the bloat.

What is Truecaller?


Truecaller is a popular caller ID and spam blocking app used by over 250 million people worldwide. It allows you to:

  • Identify unknown numbers
  • Block spam and scam calls
  • Search for phone numbers
  • See call history for numbers
  • Pay bills, send money & more

While feature-rich, Truecaller has faced criticism for its invasive data collection practices and negative impact on battery life.

Why Look for Truecaller Alternatives?

There are a few key reasons to consider switching to an alternative app:

  1. Data Privacy Concerns Truecaller collects a huge amount of personal information, including your contacts, social media info, location and more. It shares this data with third parties for ad targeting.
  2. Battery Drain Truecaller is notorious for running constantly in the background and draining battery life, even when not actively in use. This can significantly impact overall phone performance.
  3. Cluttered Interface With an increasing array of features beyond basic caller ID, many find Truecaller’s interface busy and cumbersome to navigate.
  4. Subscription Costs Many of Truecaller’s best features, like ad-free usage and advanced spam blocking, require a paid subscription. Free alternatives can provide comparable core benefits.

Best Free Truecaller Alternatives in 2024

After extensively testing the top contenders, here are my picks for the 10 best free alternatives to Truecaller for both Android and iPhone:

1. Whoscall

Whoscall App

Whoscall is one of the most popular and reliable Truecaller alternatives available. Key features include:

With a regularly updated database of over 1 billion numbers, Whoscall reliably identifies calls without sacrificing battery life or performance. Its offline database is a standout feature compared to most competitors. Learn more in our detailed Truecaller vs Whoscall comparison.

  • Real-time caller ID w/ name & photo
  • Robust spam call blocking
  • T9 dialer for fast contact search

Hiya App

Formerly Whitepages Caller ID, Hiya is a fan favorite for its ad-free experience and sleek interface. You’ll get:

CallApp offers an all-in-one communication solution, combining caller ID and call recording. Features include:

  • Identify unknown numbers
  • Block spam & scam calls
  • Record incoming & outgoing calls
  • Chat over internet
  • Blacklist specific numbers

While its spam blocking isn’t quite as thorough as some, the integrated call recording feature makes CallApp a helpful multipurpose tool. Just be aware of slightly higher background battery usage.

5. Mr. Number

Mr. Number App

Mr. Number provides reliable spam blocking and caller ID in a user-friendly package. You’ll enjoy:

  • Accurate caller identification
  • Block suspected scam calls
  • Block entire area codes/regions

Trapcall App

iPhone users in particular may appreciate TrapCall‘s feature set, which includes:

  • Unmask blocked/unknown callers
  • Automatically block known spam
  • Blacklist specific numbers
  • Record incoming calls
  • Live Caller ID

TrapCall’s “No Caller ID” feature uses a unique workaround to identify callers who have blocked their number from appearing. However, it’s currently only available in the US.

7. Callblock

Callblock App

Callblock is another option best suited for iPhone, focused on call blocking over caller ID. Key features:

  • Database of 3M+ known spam numbers
  • Blocks telemarketers, robocalls, etc.

By specializing purely in spam blocking rather than identification, Callblock boasts some of the highest successful block rates and most thorough filtering available.

8. Caller ID

Caller Id App

Another Android option, this simply named app delivers on its promise of core caller identification functionality:

  • Identify unknown numbers
  • Block spammers & scammers
  • View detailed caller info
  • Avoid uploading private contacts
  • “Favorite” important numbers

While more bare-bones than some alternatives, this Caller ID app still covers all the essentials in an easy to use format. It also touts stronger privacy by never accessing your contacts.

Available for both Android and iOS, ViewCaller offers a well-rounded set of features:

  • Integrated smart caller ID
  • Effective spam call blocking
  • T9 speed dial from main screen

10. Numler

Numler App

Rounding out the list is Numler, a newer app only available for Android. Despite its lower profile, it provides:

  • Fast, accurate caller ID
  • Offline number database
  • Reverse number lookup
  • Block numbers/unknown calls
  • Space & memory efficient

As a newer player, Numler doesn’t yet have the massive number database of bigger competitors. But it still provides dependable core features with minimal impact on system resources.

Other Notable Truecaller Alternatives
