Won’t Display True North
The app won’t display true north. It just states NA (not available) in the true north slot. And it doesn’t show why it’s NA, or what to adjust to get it to show true north. Having true north is the only reason I downloaded this app.Maxheadspace
Developer Response
This can happen for a couple reasons: 1) you have compass calibration turned off in iOS Settings (Privacy > Location Services > System Services) and/or 2) you denied permission for the app to use Location (also see iOS Settings > Privacy >Location Services). To display true bearing, the app needs both of these features to access magnetic declination.Does not point to magnetic north
Shows pointing east not accurate at all. Waste of moneyBartonecc
Compass way off
Compass is 60 degrees off Polaris in Central Ontario. No interference around in cottage country. Other compass apps and stargazing apps work flawlessly. Interface feels dated.Subbourbon
Best compass for the iPhone
This is one of the best compasses available for the iPhone, I really like that shows true and magnetic north at the same time. 5 stars well deserved.IT-Alex
Excellent app - corrects for declination
Exactly what I needfor bushwalking - a compass app that shows magnetic north AND true North together, and automatically applies the magnetic deviation based on GPS location.
Plus it reads out GPS coords and altitude, all on the same compact display.Billius44
Basically this is not a compass.
First no magnetic north. Secondly I cannot input bearing’s. Third I cannot plan a route. 4/5 star rating I don’t think so.Vince9705
Buyer’s best choice
My former app was dropped by Apple; uploaded this today and I’m in love. Bravo, Craig. Well done!CO Obs
Bought the bundle on strength of Theodolite
Downloaded the free version of Theodolite and have been so impressed and facinated with it that I was just back on the appstore and saw the offer to buy the bundle of Craig's apps.
Viewed what was on offer and even though the weather app was USA only and I live in the UK I bought the lot. For less than the price of a couple of beers I am going to have hours of fun. I didn't hesitate after reading all the positive reviews of others who are using it professionally - scientific instruments are just a hobby for me (and I now have both a real vintage 100% optical theodolite and a virtual one in my pocket ).Show lessAndy T8
Magnetic dec
Prior review (smellieboy) is not correct / fair. The Mag dec varies across NZ. Absolutely correct for my location.
Seperately, this app very neatly solves the issue with the built in iSO compass - in that the built in one foes not show if it is reading True or Mg.NZSubmariner
Emergency Location Within 10Meters Using UTM-B
I use Compass and Theodite from this developer and am very satisfied going on about 5 years now. Recently I have been encouraging my loved ones to place Pro Compass App on the first page of their iPhone with settings on UTM-B. Now if they have an emergency in today’s unstable environment, they can dial 911 and read the UTM-B number when they don’t know exactly where they are at. Especially import for our most vulnerable family members.Show lessImpSci
