Same job, very different backgrounds
Whoscall is built by Gogolook, a Taiwan-based company. Truecaller comes from Sweden and has grown into one of the largest caller ID apps worldwide. Both apps do the same basic job — the difference shows up in where they're strongest, how they handle your data, and how governments are starting to treat them.
Whoscall vs Truecaller: feature by feature
Caller ID database size
Reports a database of more than 2.6 billion entries — one of the largest reverse lookup services in East and Southeast Asia.
Doesn't publish an exact number. Its strength comes from a massive active user base constantly feeding new reports into the system.
Spam and scam call detection
Flags numbers reported by other users, paired with police partnerships in some countries giving access to verified scammer lists.
Relies heavily on crowd reporting at scale, since its user base is one of the largest of any caller ID app.
AI-powered features
Added AI tools such as a Content Checker, which scans a screenshot of a suspicious message and explains why it looks like a scam.
Offers Truecaller Assistant, an AI-based call-answering feature in some markets, plus automatic spam number blocking on Android.
URL and message scam detection
Includes a URL scanner that checks suspicious links sent through calls or messages before you tap them — a growing part of its anti-scam positioning.
Focuses more narrowly on calls and caller identity rather than link scanning, though it does flag suspicious SMS in some regions.
Android vs iOS availability
Both apps work on Android and iOS. Android gets the fuller experience on both, since Apple limits what any third-party app can do with call handling.
Which app has the bigger caller ID database?
This comes up often on Reddit threads comparing the two apps. Database size alone doesn't decide the winner, since accuracy also depends on how active users are in your specific country.
Truecaller premium apk has been collecting numbers since 2009. Its long history and enormous global user count mean fresh spam reports arrive constantly from many countries at once.
Whoscall's claimed database of over 2.6 billion entries is genuinely large. In Taiwan, Malaysia, and the Philippines, local reporting volume gives it strong accuracy for regional numbers.
Whoscall vs Truecaller, region by region
Reddit threads in r/malaysia, r/Philippines, and r/CasualPH return to this question constantly — and the answer isn't as one-sided as people expect.
Malaysia: Whoscall's home turf
Whoscall has built deep local trust through direct cooperation with Malaysian authorities — credibility a purely global app can't easily match.
Philippines: split opinion
Many users report Whoscall catches local spam numbers accurately, while others say Truecaller performs better for international calls.
Europe: GDPR slows both
GDPR restricts how freely phone numbers move between users and companies, which thins the spam database for both apps in parts of Europe.
Is Whoscall or Truecaller actually safe?
Both apps ask users to trust a foreign company with sensitive contact data — one of the most-searched safety angles in this comparison.
Uploads contact information to match incoming calls — the same basic approach every caller ID app uses — and collects device information for its spam detection engine.
Builds its database from uploaded contact lists, meaning your number can appear even if you never installed the app yourself.
Where both apps hit the same wall
TRAI, PDRM, and growing government scrutiny
Regulation is becoming a real factor in this comparison, not just a background detail.
India: TRAI vs Truecaller
India's Telecom Regulatory Authority (TRAI) has asked to be named an authorised agency under the country's IT Act, which would let it act directly against Truecaller, Hiya, and Whoscall over how they tag calls from the 1400/1600 business numbering series. TRAI argues these apps sometimes mislabel legitimate business numbers as spam; Truecaller has publicly pushed back, saying TRAI's own numbering rules made the problem worse.
Malaysia: PDRM x Whoscall
PDRM shares verified scam numbers directly with Whoscall through its Semak Mule database, and both organisations have run repeated public campaigns together since 2023 — a friction-free partnership rather than a regulatory dispute.
Whoscall vs Truecaller pricing
Both apps push users toward a paid tier once daily search limits kick in. Neither free tier matches its own paid version, so heavy spam-call victims will likely need to pay eventually with either app.
