Everything you need. Nothing you don't.
A focused toolkit for handling unknown calls — with thoughtful defaults and zero noise.
Spam detection
Real-time spam, scam and robocall flagging powered by community-curated lists.

Clean interface
Designed with Material 3 and a calm color system — no ads, no banners, no clutter.
Lightweight performance
A small APK, low memory footprint, and battery-friendly background behavior.
Community-driven
Improvements ship from real user feedback and open contribution — not growth metrics.
Privacy
Built around what you don't share.
Privacy isn't a feature we marketed — it's the default that shaped every decision.
No invasive tracking
We don't ship analytics SDKs, ad IDs, or behavior pixels with the app.
Minimal permissions
We only request permissions strictly required for caller identification to work.
User-first philosophy
Your call log stays on your device. Lookups are stateless and never tied to an identity.
Transparent development
Roadmap and changelogs live in the open — no surprise data collection, ever.
How it works
Three steps. Less than a second.
From ring to confident answer — all on-device, with no data leaving your phone.
01
Number detected
An incoming call arrives. Raider intercepts the number locally on your device.
02
Information matched
We resolve the number against trusted databases and community-flagged spam lists.
03
You decide safely
A clear, calm screen tells you who's calling — answer, ignore, or block in a single tap.
The app
Designed to disappear.
Familiar Material patterns, calm typography and one-handed reach — even on large devices.
Open & Independent
A small project, made on its own terms.
Raider CallerID is independently developed and intentionally simple. There are no subscriptions, no ads, and no aggressive monetization paths. It exists because tools like this should — not because a roadmap demanded it. Free for everyone, forever.
