## What is Gauges?

Gauges turns your iPhone and iPad into a beautiful set of live measuring instruments. Every sensor in your device, on one clean dashboard — with a full-screen gauge, live chart and history for each one.

YOUR INSTRUMENTS
• Speedometer — GPS speed in km/h, mph or knots
• Altimeter — your altitude in metres or feet
• Barometer — atmospheric pressure in hPa, inHg, psi, kPa or mmHg
• Accelerometer — g-force, live
• Magnetometer — magnetic field strength in µT or gauss
• Sound Level — ambient noise in dB
• Compass & Location — heading (magnetic or true) plus your position on a map
• Luminance — light level, straight from the camera

BUILT FOR MEASURING
• Live dashboard showing every instrument at once, with trend sparklines
• Tap any instrument for a full-screen gauge, a live 60-second chart and min/max values
• Switch units with a tap
• Mark a reading to compare against later
• Spoken readings at your chosen interval — perfect when your eyes are busy
• Share any reading instantly

GAUGES PRO
Go Pro to unlock the full toolkit:
• Record complete sessions — every instrument, sampled continuously
• Export recordings as CSV for analysis in Excel, Numbers or anywhere else
• Fine-tune every setting, including sample rate and QNH calibration
• No ads

Choose a weekly, monthly or annual plan (best value). Subscriptions renew automatically until cancelled; manage or cancel any time in your App Store account settings. If you unlocked Gauges with the original one-time purchase, you keep full access — nothing changes.

### 5/5 — Muito útil

*2026-08-23*

Oti

### 5/5 — Nifty

*2026-08-17*

Thanks for this wonderful utility.  I have been using for maybe 4-5 years or so. Every time I use it I mean to thank you, but I forget. This time I remembered.

### 1/5 — New update ruined it

*2026-08-04, version 5.1*

Ui changed for the worse and now all the ads are porn

### 5/5 — New 120 km speed limit

*2026-07-27*

‘Gauges’ is very accurate in relationship to other traffic

### 5/5 — gauges saved my marriage and raised my kids

*2026-04-03, version 4.2.2*

thank you so much gauges! you bring light into my life and tell me how much in precise detail

### 5/5 — Recompensada 100%

*2026-02-19, version 4.2.2*

Muy preciso, y intuitivo

### 1/5 — No speed

*2026-02-16*

Idea is good but no speed is recorded.

### 5/5 — Can’t say enough.

*2026-02-07, version 4.2.2*

Statistics at your fingertips.

### 5/5 — The Unknown?!

*2025-11-26, version 4.2.2*

Might have to unlock it to record some “research…”.

### 2/5 — What is the point?

*2025-05-29*

I understand that these show several different things that are built into our phones like altimeters and barometers, but what is the point of paying for a subscription to view them all? What is the use? I spend maybe 20 seconds in the app and that’s all. It has little to offer, and the information provided doesn’t help because there is little to explain the charts.

## Frequently asked questions about Gauges

### What does the Gauges app do?

Gauges is a comprehensive utility app that utilizes your device's built-in sensors to provide real-time measurements. It includes functions like a GPS, altimeter, speedometer, barometer, accelerometer, magnetometer, sound level meter, and light meter. The app displays this data through real-time graphs and can show your location and heading on a map.

### What are the key features of Gauges?

Key features include real-time readings from multiple sensors, speed displayed in various units (kph, mph, knots), GPS and pressure altitude, barometric information, accelerometer readings (G forces), location and heading, magnetic force measurement, sound level in dB, and luminance. It also offers data recording, value marking, and sharing capabilities.

### Is Gauges a free app?

The app is free to download and use with its core functionalities. However, certain advanced features, such as recording all data for spreadsheet export, viewing all sensor information at once, setting data update frequency, and enabling/disabling individual instruments, require an in-app purchase.

### What can I use the magnetometer for in Gauges?

The magnetometer in Gauges can be used for various practical applications. For instance, it can help you find hidden cameras, detect metal structures, or even identify electric wires behind walls. This feature allows you to explore the magnetic field around you.

### Can I record and export sensor data?

Yes, you can record sensor data with Gauges. For the ability to record all data and share it with other apps in CSV format, an in-app purchase is required. This allows you to analyze your sensor readings in detail on a spreadsheet or other compatible applications.

## Version history (last 5 releases)

You asked, we listened!

• The Accelerometer now shows the X, Y and Z g-forces individually, each with its own min and max — on iPhone and Apple Watch
• The Barometer reads inches of mercury to two decimals (29.85, not 29.9), with psi and kPa sharpened too
• Plus small fixes and refinements

Have a suggestion of your own? Send it from the Settings screen — this update came straight from user feedback.
