Metrix gives you a clean set of tools for the sensors, radios, network routes, clocks, audio hardware, and device details already built into your iPhone. Open the app when you want a quick look at GPS speed, compass heading, gyroscope motion, barometer pressure, battery status, Wi-Fi and cellular details, Bluetooth signals, NFC tags, camera hardware, storage, memory, screen and graphics details, audio output, biometrics, or LiDAR distance on supported iPhone models. NFC: read and inspect tags in depth chip maker, memory size, NDEF records, and decoded payloads. Metrix recognizes smart cards, transit cards, digital IDs, passports, and security keys. Write URL, text, contact, email, phone, SMS, location, and App Store records to blank tags, then erase them or permanently lock them as read-only. Bluetooth: scan nearby devices with live signal strength, decoded advertisements (iBeacon, Eddystone, device type), and a GATT inspector that connects and reads device info, battery, and services. Metrix also includes a Clock tool for local time, UTC comparison, time-zone details, and locale reference, plus Audio tools for speaker details, frequency testing, bass testing, and sound output checks. Free tools include live readouts, Checkup, public route lookup, Clock, Audio, the LiDAR dot-map distance view, NFC reading and basic writing, and Bluetooth scanning with GATT inspection. Metrix Pro is a one-time purchase that adds Find It, a live Bluetooth proximity finder with a distance ring, intensifying haptics, a direction hint, and 1 m calibration. Plus saved history, recordings, snapshots, saved Bluetooth, Wi-Fi, and NFC items, device nicknames, watches, a trip computer, exports and reports, NFC import/export, advanced NFC writing (Wi-Fi, custom MIME, external, and multi-record tags), and Wi-Fi/cellular speed tests. Metrix does not require an account and does not use ads, analytics, or tracking. Anything you save with Pro stays on your device unless you choose to export or share it. Readings depend on device hardware, iOS permissions, signal quality, location quality, and sensor availability. ## Key features - Sensor readouts (GPS, barometer, gyroscope) - NFC tag reading and writing - Bluetooth device scanning and GATT inspection - Audio output testing - LiDAR distance mapping - Network and device details ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Metrix Pro | $4.99 | one-time | ## Frequently asked questions about Metrix Toolkit ### What is Metrix Toolkit?
