I’m dumb but I’m sure it’s useful🤷🏼♂️
I don’t understand it but it seems really cool and useful for researchers and Chat gpt actually recommended it to me. This is now gonna be my compass app.
Terrible app
This is king Jack and it doas not do what it was supposed it was glitchy and not correct no one should use this app it’s terrible
Excellent and extremely useful
I often use a mirror compass in conjunction with a spotting scope at peaks or lookouts. I use this combination for looking at features marked on the map or at night in conjunction with astronomy apps which give times and bearings for spotting things such as the space station.
So I find this app a great quick and easy way of getting mag information for wherever it is I happen to be.
Highly recommended.

Needs a slight facelift
I’m always appreciative of being given opportunities to contribute to wards citizen science, I just wish they’d give the UI on this app an update. It looks best on an iPhone 4 screen. There’s so much more potential with an interface update.
Was great, but latest update is broken
Per title, latest update broke the app - magnetic declination is zero, i.e. true north = magnetic north
Seems cool....but setting options need work
I am unable to enable background recording because my location data isn’t set to “Always” but I don’t have an “Always” option for the app in setting. Only Never and While Using App.
No location
iPhone XS Max —- doesn’t grab GPS location. I emailed back and forth with support. Known bug. Fix for 5 stars.
1.7.5 cannot take location from at least some iPhones
iPhone 5s 32GB iOS 12.1.4 App never acquires location data from the phone and therefore never records data. I reported this to NOAA just last week. It would be interesting to hear from people using newer, more capable iPhones, although no mention is made of any limitations on older phones.
Makes a very nice compass app though.

CrowdMag is useless.
It has a bug with my iPhone7+, iOS 12.1.4
Its not grabbing my gps data from phone.
It has no info/help tab.
Why use a Mag model at all?? If we are going to provide mag heading, dip and uT, app could compute/derive nPole location from all our inputs. App could then plot it in quazi real time, send alerts etc.
An almost good app but...

Zero effort to contribute to cool research
Just open the app and set how often you want to send them data. These types of apps are a great way to harness the power of your iPhone and with no effort make a positive contribution. Nice touch adding achievements for contributions and locations. The magnetic information is interesting to see but that’s about it. Just know your contribution will help other researchers.

Excellent Info
I travel the world for a living. Knowing the correct Mag Variation has come in handy. The latest version includes an excellent compass which gives both True and Magnetic North. It is nice to be able to contribute information for this program. I find that it doesn't effect my battery usage that much.

Useful
I love this app. I'm out in the field a lot and this app allows for quick calibration of my compasses.
Drains Battery
I really want to contribute geomagnetic data to CrowdMag, but since installing the app my batterry drains in half the time. Sadly, I have to uninstall.
Essential!
I am a photographer and I use this app to find the magnetic declination of my current location so that I can correct my compass readings to true north to match with the true north bearings given in some landscape photography planning apps.
Citizen Science
Great use of millions of mobile sensors!
