About WhatPhone
The most private, accurate, and effortless way to discover what phone you're holding — right in your browser, with zero data collection.
Our Mission
To empower every smartphone user with instant, accurate device information while respecting their privacy completely. No apps, no accounts, no tracking — just the information you need, when you need it.
The Story Behind WhatPhone
WhatPhone was born from a simple frustration: trying to help friends and family identify their phone models for tech support, warranty claims, or selling devices. Existing solutions either required downloading suspicious apps, sharing personal data, or provided incomplete information.
We asked ourselves: why can't device detection be instant, private, and free? So we built it. WhatPhone uses only browser APIs — everything runs locally on your device. Your data never touches our servers because we don't have any servers collecting data.
Today, WhatPhone helps thousands of users daily identify their devices, check specifications, and debug technical issues — all while maintaining complete privacy.
Zero data transmitted
Our Core Principles
Absolute Privacy
We don't collect, store, or share any data. No analytics, no logs, no cookies. What happens in your browser stays in your browser.
Instant Results
Detection happens in milliseconds. Click the button and your full device report appears immediately — no waiting, no loading screens.
Universal Access
Works on every modern browser and device: iPhone, Android, tablet, desktop. No app store, no installation, no permissions required.
Unmatched Accuracy
Combining User Agent parsing, Client Hints, screen resolution fingerprinting, and hardware APIs to deliver the most accurate detection possible.
Forever Free
WhatPhone will always be free. No premium tiers, no paywalls, no subscription. Device information should be accessible to everyone.
Developer Friendly
Export full JSON reports, copy UA strings, test WebGL/WebGPU support — built for developers debugging across devices.
Why WhatPhone Stands Out
Unlike other "device detector" tools that secretly sell your data or require invasive app installations, WhatPhone was built with a radical privacy-first philosophy. We don't need your email, your location, or your permission to access anything beyond what your browser already shares. Every detection is processed locally, and the results disappear when you close the tab.
30+ detection points
Built on Modern Web Standards
WhatPhone leverages cutting-edge browser technologies including the Navigator API, Screen API, Battery Status API, Network Information API, and Device Memory API. On supported browsers, we also use User-Agent Client Hints for more precise model identification.
Our detection engine continuously updates to support new devices from Apple, Samsung, Google, OnePlus, Xiaomi, and 50+ other manufacturers. We combine multiple signals — user agent patterns, screen resolutions, GPU renderers — to infer the exact model even when browsers obscure identifiers for privacy.
100% transparent. You can inspect our code, see exactly how detection works, and verify that no data leaves your browser.
Made with privacy, for everyone
WhatPhone is an independent project driven by a passion for user privacy and technical excellence. We believe that essential tools like device detection should never come at the cost of your personal data.
