Works good..... I would normally give it 4 stars, but I gave it 5 to offset the complainers why can't read!

Very cool and almost to futuristic love it!. Great app I could measure the magnetic field of my new rewound coil on my older outboard engine 👍😁

Great fun.... Working better but still a little wonkie at times.

This is great. Using all features to an advantage on the 3gs, keep it up and we can see the full potential from this device!

Vice nice. This is an excellent app, doing everything that is advertised. The arrows give a clear view of the direction of the magnetic field and the acceleration. They are a lot easier to visualize with this than by looking at the raw sensor numbers. I especially like the magnetic declination view. This is useful for learning about magnetism as well as seeing what kinds of fields are emitted by various devices around the house.

Great app....helped my doctor find mag fields in her office. Great app

Super Awesome Magnetometer. Very good app. Impressive 3 dimensional magnetometer read out. I was pleasantly surprised by how good this is and seems to be quite accurate and sensitive. Well done.

Erratic. The magnetometer function works OK but not in all modes. The compass star rotates briefly after the built-in compass has been activated but then locks up. The accelerometer doesn't respond at all, it just gives a fixed red arrow. Good for entertaining a 4-year-old using a little magnet to make the blue arrow dance; but that's about all.

Junk. Doesn't work as stated

It looks cool!. But im 14 i have no use on it... Buts it works

Great, but could use a few more features.. I love the 3D visualization of the sensors. It would be cool if it included the gyro data as well as logging. It could be useful for science experiments.

Fail！. Doesn't work！no use。

I Need This!. Just when I thought I had everything. Definitely a cool app with a multitude of uses. Nice Interface good online manual and works exactly as advertised.

Very awesome. This app is so cool. I use it all the time when I'm messing around in my yard. I can usually always find some rocks that are magnetic or a random piece of metal. Very fun to use.

Awsome. Great product

Needs logging feature. ...otherwise this app is great!

Very Nice. This app is dynamite. Very educational about the physical world. After turning off "Screen Rotation" the screen will nevertheless rotate once before locking.

FUNdamental. There needs to be more apps like this! (Apps that use APIs to give you fundamental information of the world around you) This allows you to view the direction and intensity of the magnetic field around you.

Actually works. Works well on iPhone 4! Tried it with a magnet and the speakers for the magnetic setting, then tried the accelerometer which also works.

Mr. Good magnetometer

Very cool magnetometer. Works great. Can't understand why people have to give it a bad rating because they have the wrong device! Fun for exploring grav/mag and impressing Geophysicists at parties. Wish it had labels for the modes, why should any one have to remember, guess or worse yet stop the app and go to the home page to to figure that out?

Doesn't work for me :(. I guess my iPod doesn't have the right hardware. I bet it would have been cool if it did work for me though.

Crap. I just got ripped off!!!

I can't get a name. Doesn't works on ipod touch 8gb

Great app. Work well on my 4S. I would suggest not getting strong magnets near the phone. It will not hurt the electronics, but it could make the phone frame slightly magnetic and interfere with the compass.

Awesome app. I love this app

Funny little timewaster. I only got this literally 45 secs ago, I haven't played around with it but it would be a good gag app

Works perfect. Works exactly as described. People need to read and stop rating it one star because they don't have a 3gs. My phones magnometer usually resets around 140, so not for strong magnets. Occasionally the reading will spazz and get stuck, but I just reset it (yellow button in relative mode). If you have a 3gs this is a very cool app!

Interesting, scientific, and fun. This app reveals the otherwise invisible local magnetic field with a full 3D vector indicator and several selectable modes of operation. Really fun to experiment with. Nicely done!

Coolest app ever. Works exactly as described. Anybody with any scientific interest or leaning should spend a dollar and get this thing!

Awesome. Works better than I expected. People have no clue what they are talking about . . . "encouraging people to put magnets around electronics". All electronic devices with a current (ie on) produce an EM field. Learn some physics folks. This is a really cool app.

Looks Good. I got it because I have always been interested in magnetics.

High gadget factor. I'm not sure how this app could look any cooler than it does. It really helps you visualize the invisible forces acting on the iPhones sensors. This must be what evil geniuses play with when they aren't trying to kill James Bond. All I need now is a monocle and a white Persian cat.

Magnets?. We are encouraging people to place magnets around and on electronics because why???

Gaussian around. This app is quite sensitive and visually impressive. I've been measuring Gauss units from my various devices, iPod Touch, iPad, Kindle, etc. I'm wondering what impact, if any, those fields have on me? For example, do those devices near my head contribute to insomnia or other possible health issues? Useful app! Very interesting.

Dr.. Does not work on iPod. Should be stated more clearly. iPod does not have magnetic sensor, from what I can gather.

Responsive and precise. If you wanted a tricorder, get this app. The arrow reflects magnetic flux very quickly and shows the field strength in real time. It's 99 cents and does a fantastic job of representing 3d magnetic fields. The new version has the compass overlay working correctly. I've bought only a handful of apps and this is one. It's a very impressive app to anyone who is science minded.

Great app for techies!. Works as stated. Great app!

Potential.. It has potential. Provides some neat info from the iPhone's sensors. Fun to play with.

Fun. Fun to play with it!

Excellent after latest update. I have used this app since the iPhone 3 came out to locate and find the orientation of hidden magnets. It stopped working for me after IOS 9 but the recent update has it working better than ever on an iPhone 6s Plus. I highly recommend it, especially with the new features.

Nice app. Excellent app (the only one ive ever been tempted to pay for) and considering the hardware, quite sensitive. Would be be very interesting to allow users to log absolute data with location to allow crude magnetic maps of favourite or target areas to be produced. Keep working on this, very cool!

Good App, deserves better reviews. I bought this app to use it for what it was designed for, visualizing the Earths magnetosphere knowing that it would be limited by the fact these are phones first, instruments of science second. In this role it performs very well & is far less expensive than any comparable instrument on the market. I would like to overlay the magnetic field displayed on an image from the camera. This would mean different vector display probably but it would be very useful. I also think that the ability to tie location services to the vector display would improve its usefulness and lastly logging over time either with camera image or GPS location or both at the same time. Sometimes the populace of the world doesn't realize the marvels that small technology has brought us. To the producers of this app, good work, please don't stop here!!

Cool app. Very sensitive and useful app with an easy interface. Just avoid the temptation to put magnets too close to the iphone while playing with the app :)

Unimpressed. Could not see a very strong rare earth magnet held within 10mm of my iPhone.

Can not calibrate. On the iPad Pro the magnetic north is always wrong. The app provides no way to force a calibration.

I like it, but.... I really liked this app when I first got it, back during iOS 4.1. It worked really well and I couldn't stop playing with it. But after I updated to iOS 4.2, it just doesn't seem to operate quite the same. It can still measure fields, but its responsiveness seems diminished. This is most likely no fault of the creators since it was the iOS update that did it, but I would like it if it could be as good as when I first bought it again.

Fantastic. Had this one back when I still had a 3GS I believe, loved it then and love'n it now.
