5 Best Apps to Make the Most of Apple Sensors

5 Best Apps to Make the Most of Apple 

Sensors are a big part of what makes smartphones smart, and Apple mobile devices are packed with them. Most of us use at least some of them every day -- even if we don't realize it -- but there are also apps out there that let you take them even further for a variety of fun and useful purposes. Read on for a look at the five best contenders for iPhone and iPad.

No. 1: Commander Compass Lite

Commander Compass Lite is rated 4 1/2 stars out of a possible 5 for all versions based on 4,429 ratings, and 4 1/2 stars out of 5 for the current version based on 895 ratings in the iTunes App Store.

This compass app takes advantage of the magnetic compass magnetometer that's included in recent iPhones and iPads to display directional navigation data -- just like a handheld compass. Position, bearings and speed are tracked.

Heavily magnetic fields can interfere with magnetometer readings, so this app starts using a gyroscopic rotational sensor to compensate for that, as well.

No. 2: Planets

Q Continuum's Planets is rated 3 1/2 stars out of a possible 5 for all versions based on 53,222 ratings, and 4 1/2 stars out of 5 for the current version based on 223 ratings in the iTunes App Store.

Here's an app that takes advantage of the gyroscope sensor. Gyroscopes track localized movement of a device.

Planets is a 3D planetarium-style guide to the solar system. Once the device locks onto a location using GPS or cellular towers, movement of the device maps the planets and stars on the screen with the gyroscope in real time.

No. 3: AccelMeter - 3D Vector Accelerometer

AccelMeter is rated 3 stars out of a possible 5 for all versions based on 269 ratings, and 3 1/2 stars out of 5 for the current version based on 16 ratings in the iTunes App Store.

Whether you knew it or not, the accelerometer is the sensor that orients the phone screen between landscape and portrait -- you've likely been using your device's accelerometer daily when Web browsing, looking at photos and controlling any games.

Peter Breitling's AccelMeter is the best app for visualizing and measuring actual acceleration. It includes all of the three axes -- often labeled x, y and z -- plus reverse acceleration and g-force calculations.

No. 4: Dimmer

Dimmer is rated 3 stars out of a possible 5 for all versions based on 272 ratings, and 3 stars out of 5 for the current version based on 155 ratings in the iTunes App Store.

The light sensor on your iPad or iPhone automatically adjusts screen-brightness levels based on what the Apple programmers think should be optimum brightness -- based on ambient light. Well, that may not be what you think, and this app lets you adjust sensors manually.

Be aware that a dim screen will save power, while a brighter screen makes small screens more readable.

Sleep therapists reckon a burst of light at night fools the brain into thinking it's waking-up time, so use a super-dim screen if you're an insomniac workaholic.

No. 5: Sensor Monitor

Sensor Monitor is rated 4 1/2 stars out of a possible 5 for all versions based on 24 ratings, and 4 1/2 stars out of 5 for the current version based on 11 ratings in the iTunes App Store.

Here's an app that lets you display and log raw sensor values for the accelerometer, gyroscope, compass, GPS, battery, microphone, touch and proximity sensors.

The proximity sensor is the sensor that deactivates the display when the phone is in a call so you ears don't dial phone numbers.
