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...
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.
No location

iPhone XS Max —- doesn’t grab GPS location. I emailed back and forth with support. Known bug. Fix for 5 stars.
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.
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.
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.
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.
Useful

I love this app. I'm out in the field a lot and this app allows for quick calibration of my compasses.
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.
