Professional Detection in Your Pocket

Real-time magnetic field sensing powered by your iPhone's hardware

Real-Time Detection

Watch the magnetic field strength react instantly as you move your phone. The animated gauge and haptic feedback let you physically 'feel' metal objects through vibrations that intensify as you get closer.

High Precision Measurements

Measures magnetic flux density in microteslas (uT) with raw sensor data accuracy. Perfect for finding wall studs, locating lost screws, tracing wires, or detecting magnetic interference sources.

3-Axis Detailed Analysis

View the full X, Y, and Z axis breakdown of magnetic forces in real time. Analyze interference patterns to identify the source and direction of magnetic fields with scientific precision.

Dark Mode Built-In

Designed for low-light environments where you need it most. Whether you're scanning in an attic, under a desk, behind a wall panel, or in a crawl space, Flux is easy on the eyes.

Why Choose Flux?

The metal detector app built for accuracy and simplicity

No Extra Hardware

Your iPhone already has a built-in magnetometer sensor. Flux unlocks its full potential — no external devices, dongles, or accessories needed.

Haptic Feedback

Feel the metal before you see it. Flux uses haptic vibrations that intensify as you approach a metal object, giving you physical feedback in real time.

Scientific Precision

View magnetic flux density in microteslas with full 3-axis breakdown. Export readings for analysis. Trusted by hobbyists, DIYers, and professionals alike.

What Can You Detect With Flux?

🏗️

Find Wall Studs

Locate wooden and metal studs behind drywall. Flux detects the nails and screws holding studs in place, giving you accurate framing locations.

⚡

Trace Hidden Wires

Follow electrical wires behind walls by detecting the magnetic field they generate. Useful before drilling or hanging shelves.

🔧

Locate Pipes

Find metal water pipes, gas lines, and ductwork hidden behind walls, under floors, or in ceilings before starting renovation work.

🔍

Find Lost Objects

Locate lost screws, nails, jewelry, or other metal objects in carpet, grass, sand, or cluttered workspaces.

📡

Check EMF Levels

Measure electromagnetic field interference near electronics, appliances, or power lines. Useful for identifying sources of magnetic noise.

🏢

Rebar Detection

Detect rebar and metal reinforcement in concrete slabs, walls, and foundations. Essential for construction and renovation planning.

Frequently Asked Questions

Flux is a professional-grade metal detector and magnetometer app for iPhone. It uses your phone's built-in magnetometer sensor to detect magnetic fields, locate hidden metals, and measure magnetic flux density in real time.
Flux reads your iPhone's built-in magnetometer sensor, which measures magnetic flux density in microteslas (uT). Metallic objects — especially ferrous metals like iron and steel — distort the Earth's magnetic field. Flux detects these distortions and alerts you with visual gauges, numerical readings, and haptic feedback.
Flux is perfect for finding wall studs, locating hidden wires and pipes, detecting lost screws or nails, finding rebar in concrete, checking for magnetic interference near electronics, and general magnetic field analysis.
Flux uses your iPhone's hardware magnetometer, which provides reliable readings for everyday detection tasks. While it won't replace industrial-grade equipment, it's surprisingly effective for home projects, DIY renovations, and general metal detection.
Yes. Flux works completely offline. It reads directly from your device's magnetometer sensor and does not require an internet connection.
Flux is free to download with core detection features. Premium features like advanced 3-axis analysis, recording, and export are available via a subscription or one-time purchase.
Yes. The magnetometer sensor works through phone cases. However, magnetic cases or cases with metal components may affect readings. For best accuracy, remove magnetic accessories.
Absolutely. All sensor data is processed locally on your device. Flux does not collect, store, or transmit any personal data or scan results to external servers.
