Speak any language.
Understand any caller.

Live, two-way voice translation while you're on the call. Your caller speaks Hindi — you hear English. You reply in English — they hear Hindi. In real time, with no app switch, across 50+ languages. No other caller-ID app does this.

The smartest caller-ID overlay you'll ever use.

A draggable card floats over every incoming and outgoing call — telling you who's on the line, scoring the risk, and giving you Block, Report and Dismiss in a single tap. Powered by a crowd-sourced spam network that gets sharper every day.

  • Live caller ID for every unknown number

    Name, number and location appear the instant the phone rings — even when the number isn't in your contacts.

  • Auto-block spam in real time

    Numbers with a high spam score are silently rejected by our CallScreeningService — your phone never even rings.

  • A call log that actually makes sense

    Spam badges, verified checkmarks, time-ago avatars and merged device contacts — your history, finally readable.

  • Personal blocklist that follows you

    Block any number from four entry points. Your blocklist syncs across every device you sign in on.

Everything TraceCallerID Does

Twelve categories of caller intelligence.
Zero clutter.

TraceCallerID is one focused product, organised around the moments that actually matter — the ring, the translation, the block, the report. Tap any card to dive into the full feature breakdown.

Caller ID Overlay

Truecaller-style draggable card on every incoming and outgoing call, with live name, location and spam score.

Crowdsourced Intelligence

Community-built directory with SHA-256 hashing, weighted trust scoring and consent-aware uploads.

Block Management

Native blocklist with auto-reject via CallScreeningService, four block entry points, and full backend sync.

Spam Reporting

Six categories, optional comment, server-aggregated scoring — every report makes the network smarter.

Background Services

Foreground service, InCallService, BootReceiver and a React Native bridge — Android lifecycle done right.

SHA-256 hashing before upload, opt-in raw numbers, GDPR wipe endpoint, anonymous trust weighting.

How It Works

Protected on your very next call

Three simple steps from install to live caller ID.

1

Install TraceCallerID

Get TraceCallerID from the App Store or Google Play — it's lightweight, free and no signup is needed to start.

2

Sign in with your phone

A 6-digit OTP arrives by SMS and is auto-detected from your inbox. No passwords, no lengthy forms.

3

Grant the right permissions

Approve the bulk permission request and (optionally) make TraceCallerID your default dialer for full screening.

Why TraceCallerID

Built to respect your time, your data and your phone

One focused product — engineered for performance, transparency and the long term.

Real-time, every time

Native foreground services and a 6-hour Redis lookup cache mean the overlay appears the instant your phone rings.

Privacy-first by design

Phone numbers are SHA-256 hashed before upload. Raw numbers are stored only with explicit consent — and wipeable in one call.

One job. Done well.

No bloat, no sub-apps, no upsell carousel. Just a single focused experience that does caller ID and spam defense properly.

Built for India and beyond

English and Hindi out of the box, full E.164 normalisation with an Indian default region, and an i18n stack ready for more languages.

Loved by users

Real people. Real silence.

Here's what early adopters are saying after switching to TraceCallerID.

"TraceCallerID silenced the dinnertime robocalls in 24 hours. The High Risk badge is the best feature my phone has ever had."

"What sold me is the privacy posture. SHA-256 hashing before any upload, and a one-tap wipe. That's a caller ID app I can recommend to my parents."

FAQ

Questions, answered

If there's something you'd like to know that isn't here, our support team is happy to help.

Is TraceCallerID really free?
Yes. Sign-in, the overlay, the call log, the blocklist, reverse lookup and spam reporting are all free. The app is ad-supported with an optional premium upgrade that removes ads and bumps up your contribution trust weight.
How does TraceCallerID identify unknown callers?
When the phone rings, our background service queries the TraceCallerID backend for that number. The backend aggregates community contributions using a weighted formula (recency × frequency × trust × weight) to return a canonical name and a real-time spam score in milliseconds.
Does TraceCallerID upload my contacts to the cloud?
Phone numbers are SHA-256 hashed on the device before anything leaves it. Raw numbers and contact names are only stored on our servers if you've explicitly opted in via consent_share_names=true. You can wipe every contribution any time from Profile → Privacy.
Do I need to set TraceCallerID as my default dialer?
Not strictly. TraceCallerID works as an overlay-only app for live caller ID. For the full experience — silent rejection of high-spam numbers via CallScreeningService and InCallService-driven overlays — making it your default dialer unlocks the most reliable behaviour.
Which devices does TraceCallerID support?
TraceCallerID is built for Android, with full support for Android 10+ (CallScreeningService, ROLE_DIALER) and a PhoneStateReceiver fallback for older versions. Your account, blocklist and preferences sync across every device you sign in on.
How do I delete my account and my data?
Head to Profile → Privacy → Delete Account. Your account and any raw data we hold cascade-delete on the backend. Anonymous, hashed contributions to the spam network can be wiped separately via the /contacts/all endpoint, also exposed in the same screen.
