NewcallerCaller ID on every call
See a name, a verified badge or a spam warning on top of the incoming-call screen, then call back, block or report from the after-call card.
Caller ID & spam protection for Android
Know who's calling. Stop spam before it rings.
Newcaller names unknown callers, flags fraud and telemarketing using reports from people like you, and blocks the worst offenders automatically — without uploading your contacts.
- Contacts stay on your phone
- Verified business badges
- No spam label from a single report
Features
Everything you need when the phone rings
Caller ID, spam protection and a smarter call history — designed around trust, not guesswork.
Automatic spam blocking
Block top spammers from a community list kept on your phone, plus likely spam, hidden and international numbers. Your contacts are never blocked automatically.
Verified businesses
Banks, couriers and hospitals carry a green badge with their category, hours and website — so a real customer-care call stands out from an impersonator.
Community reports, fairly scored
Each person counts once per number, older reports fade, and “not spam” feedback pulls a score down. One report never brands a number as spam.
Search and directory
Look up any number, or browse verified businesses by category. Private individuals can't be found by searching their name.
A complete calling companion
Call history with caller ID, contacts, a dialer that identifies numbers as you type, a protection hub, and light and dark themes.
At the moment it matters
Warnings before you answer, actions after you hang up
Newcaller checks unknown callers against your block list and the community spam list instantly, so blocked calls never ring.
- Colour-coded caller ID: green for verified businesses, amber for suspected spam, red for likely spam
- The popup steps aside when you answer and returns as an after-call card
- Quiet notifications tell you when a spam call was blocked
Every number tells its story
Profiles that explain, not just label
Open any number to see why it's flagged — or why it's trusted.
- Spam score, how many people reported it and what they reported
- A six-month trend and a public activity timeline
- Business details, name suggestions, line type and your own call history with the number
Protection hub
You decide what gets through
Turn on the protections you want and see what Newcaller has blocked for you.
- Block top spammers, likely spam, hidden numbers, international calls — or everyone not in your contacts
- Trending scams in the community and the most-reported numbers
- Your block list and blocked-call history in one place
How it works
Set up in a minute
Every permission is optional and explained, and you can change them anytime.
Verify your number
Sign in with a one-time code sent by SMS. Your name stays private unless you choose to share it.
Turn on protection
Set Newcaller as your caller ID & spam app so it can screen calls before they ring (Android 10 and later).
Calls get identified
Unknown callers show a name, a verified badge or a spam warning. Spam you've chosen to block never rings.
Help others
Report spam or suggest a caller's name. Signed-in reports keep the community list accurate for everyone.
Spam scores
Fair to callers, honest with you
Every number gets a 0–100 spam score from reports by signed-in people. Labels need agreement — not one angry report.
Under review1–2 people reported it. Shown as a signal, never as spam.
Suspected spam3 or more people reported it.
Likely spam5 or more people and a high score.
Confirmed spamReviewed and confirmed by Newcaller moderators.
One person, one vote. Reporting the same number again updates your report instead of adding another.
Reports fade. Older reports gradually count less, so reassigned numbers can recover.
“Not spam” counts. Feedback that a number is legitimate pulls its score down.
Privacy by design
Your phone, your data
Caller ID shouldn't cost you your address book. Newcaller is built to need as little as possible.
Contacts never leave your phone
They're used on-device to show names and to make sure your contacts are never blocked.
Call history stays local
Only unknown numbers are looked up to identify them.
Lookups don't create records
Looking up a number doesn't add it to Newcaller's database.
Your name is opt-in
People see your name only if you switch on “Show my name as caller ID”.
Reports stay confidential
Who reported a number, and what they wrote, is visible only to moderators.
Delete anytime
Deleting your account erases your profile and caller ID name.
Newcaller's servers run in India (AWS Mumbai). Sign-in codes are sent and verified by Google Firebase.

For businesses
Make sure customers pick up
Verified businesses get a green badge on every call, plus their category, hours, address and website on their Newcaller profile — and only verified businesses can be found by name in search.
FAQ
Questions, answered
Does Newcaller upload my contacts?
No. Your contacts are read on your phone to show names and to make sure contacts are never blocked automatically. They're never uploaded.
How does a number get marked as spam?
From reports by signed-in people. One or two reports only mark a number as under review. It becomes suspected spam after three people report it, and likely spam after five or more with a high score. Older reports count less over time, and “not spam” feedback lowers the score.
Will people see my name when I call?
Only if you turn on “Show my name as caller ID” in your profile. It's off until you choose to share it, and you can turn it off anytime.
What happens when I look up a number?
The number is sent to Newcaller to fetch its caller information. The lookup doesn't add the number to Newcaller's database.
My number was reported unfairly. What can I do?
Reports fade over time, people can mark your number as not spam, and Newcaller moderators can dismiss reports. A single report is never enough to label a number as spam.
Which phones are supported?
Android 8.0 or later. Screening and blocking calls before they ring needs Android 10 or later.
Can I delete my account?
Yes, from Settings in the app. Your profile and caller ID name are erased; spam reports you made remain only as anonymous signals.
