Perfect Mark is a tool for more precise GPS location & coordinate capture. You can save coordinates on iPhone, send them in email, copy to iPhones memory (clipboard) or open them in Google Maps.
Most of the time GPS receivers are not very precise due to small GPS antenna, surrounding buildings or even bad weather. Perfect Mark solves this problem by allowing you to capture coordinates multiple times and automatically calculating center point afterwards.

Pros and cons of Perfect Mark app for iPhone and iPad
Perfect Mark app good for
I just wanted this app so that I could copy my GPS coordinates to my clipboard. It seems this may be the only app in the app store that does that. How bizarre if thats true, but I did a search for "gps clipboard" and this was literally the only app that came up. It does what it says without any issues. Im happy. :)
Even the altimeter is working. Could you please add a setting to change meters to feet. Even though it world be good for me...my brain just doesnt do metric.
Averaging > 50 locations can significantly improve the accuracy of the final measurement. This should be the standard for ALL those setting up a Geocache.
After downloading I tested it on one side of the house (inside). The average point put me exactly where I was sitting. When I had the map show my current location, it was at least 20 off. Pretty amazing!
Some bad moments
I just purchased this. The app support link goes to a 404 error. When I switch on automatic averaging the app stops responding after a minute or so. The format is not adapted to the iPhone 6. Not recommended although not sure what else can do gps averaging well.
Does not work in 2014, freezes and hangs. Deleting after first trial. Read this review and be warned.
In iPhone 6 Plus with iOS 9.3.1 , this app crashes at start up. Couldnt use it a single time. Some update coming ?
This app starts but then immediately crashes on my iPhone 6+. The developers website appears to be out-of-service. Dont buy this app.
I couldnt get the app to start. Didnt work at all.. I want a refund.
This app was just what I was looking for; averaging the GPS position for high accuracy but the screenshots show altitude is included but it does not work for me!! If altitude is included it will be 5 star.
