1. Fixes an issue, when using the "Offset Position" setting option, in which the course you are traveling crosses north in a counter-clockwise direction. This caused the center of the display to jump. 2. When creating a Point-of-Interest on the map, an option was added to input the new Point-of-Interest's Latitude and Longitude in degrees using the keyboard. Previously, the operator had to choose between the touch point on the map or by having the App use the current GPS position.

Version 12.0(1): Fixed an issue where the disabling of the 'Offset Position on Map' switch was not recognized by the software performing the offset in the case where the speed was greater than 20 mph. Recent Version 11.0(11): 1. Added an alert in the Map View when the operator: 1. Starts a track 2. Stops a track 3. Clears a track in order to tell the user to either continue or cancel out of the action. 2. Added a third, selectable, Lat/Long type: DDD MM.MMMM to the Main view and Map view 3. Added the capability to dynamically move the center point on the map in order to have the track position nearer either side/top/bottom as the course changes. In this way you see more of what's ahead of you on the map and not so much what's behind you. This capability can be enabled or disabled by a new switch, in the Settings view, callled "Offset Position On Map Enabled". The setting is saved to disk and will be reread on startup. This functionality will take effect only for speeds greater then 20 MPH and will be disabled when the speed is less than 15 MPH. 4. Updated the NOAA World Magnetic Model from the 2020 version to the latest, 2025 version. (NOAA updates these approximately every five years). This is used by the CourseSpeed APP to compute declination, which allows the course to be displayed relatiive to magnetic north as well as True north. 5. When using the Mark as a geocache, when the reported GPS position accuracy is low, allow averaging of the a lower accuracy report occasionally in order to continue to average the position of someone that is moving. 6. Added two alerts concerning the 'Use Mark as Geocache Location' switch and the 'Offset Position On Map Enabled' switch. If the user enables both switches, an alert will warn the user that having both switches enabled simultaneously may cause the map screen to offset its center, while geocaching, if low accuracy GPS reports are received. 7. Updated the "About" text.

If the user enables both switches, an alert will warn the user that having both switches enabled simultaneously may cause the map screen to offset its center, while geocaching, if low accuracy GPS reports are received. 7. Updated the "About" text.

Version 9.1.1: 1. Added the fields: -- Cache Lat Distance, -- Cache Lon distance, and -- Cache Avg Count to the CourseSpeedWatch app whenever the "Use Mark as Geocache" switch is set to 'on' in the CourseSpeed iPhone App's 'Settings' view.". These fields are calculated by the CourseSpeed iPhone App. 2. Changed the number of GPSr reports used for averaging a geocache location from 50 to 10 in the CourseSpeed iPhone App.

Fixes an issue when using the Mark as a geocache. The values for the distance to the latitude line and distance to the longitude line of the geocache were incorrect.

1. A new feature has been added for Geocaching. The new feature allows for finding the given cache location by providing two independent distances to the geocache, one in the north-south direction and one in the east-west direction. This makes it easier to zero in on the cache. In addition, only the GPSr positions marked with the best accuracy (by the GPSr) are used in the averaging of the user’s current location. (Note: Geocaching is a “treasure hunt” using a GPS receiver, like the one in your iPhone! See the geocaching.com web site for details about geocaching). 2. In the Map View, the Magenta track line distance has been fixed to be displayed in the distance units selected by the user in the Main View. Previously, it had been displayed only in miles. The red track distance did not need to be fixed as it was already displayed in the proper distance units. 3. In the Settings view, the choices for the type of course smoothing have been simplified to only one type.

Version 8.18(0) - Fix for occasional App crash seen in V8.16(5).

Version 8.17(8) - Removed the settings switch for displaying speeds near zero (i.e., less than 1). Now, the lowest displayed speed will be 1. - Added a settings switch to allow the user to select speeds less then 10 to be displayed with or without a fraction.

Version 8.16(5) - Fixed a startup issue in V8.15(11) where speed was not set to zero in a timely fashion in the case of a stationary user but the first GPS location indicated a non-zero speed. Also contains recent Version 8.15 changes. Click on the Version History link to see those changes also.

Version 8.15(11) - Added an Anchor-Watch function, for boaters, that sounds an alert tone when a boat at anchor is found to move by an unacceptable distance, selectable by the user. The selectable distance is saved to a file in order to have the same setting when restarting the App. - Changed Speed-Made-Good-to-Mark functionality to Speed-Made-Good-to-Windward. Added operator entry for wind direcction and as a switch in the Settings view to enable the Speed-Made-Good-to-Windward function. Saved the value of wind direction and the enable/disable status of the new switch to a file in order to have the same settings when restarting the App. You can still add a Mark on the map and still see the distance and bearing to the Mark in the same fields on the Map view. - Fixed an issue in the Map View where a track history could not be stopped if a waypoint was added to the current track history track and there was not a GPX track recording started. - Better rejection of obviously bad GPS receiver locations. - In certain instances, when it is questionable whether the GPS receiver's speed or course is correct, we are computing speed and course from the last two GPS receiver latitude/longitude pairs instead of using the GPS receiver values for speed and course. - When course is changing quickly, e.g. turning sharply, display the new course immediately instead of passing it through the course smoothing algorithm. - Other, non visible improvements.

Version 8.14(2)  Removed a change made in Version 8.13(3) that inadvertently caused the Map view to be updated at a slower than normal rate.

Version 8.13(3) - Corrected the algorithm for computing "Julian Day" to include the current time zone offset from UTC time. Julian Day is used in all astronomical calculations, including in the CourseSpeed App's Apple Watch "Sun Rise/Set" complication showing sunrise and sunset times of day. - Other, non visible improvements.

V8.12(2) - Added an Apple watch "complication" to show the times of Sunrise and Sunset at your current location. The times are calculated and updated periodically as the Sunrise and Sunset times will change based on your current position. The calculations for the times of sun rise/set take into account the light refraction at the horizon as well as the radius of the sun. Both are needed in order to accurately represent the time at which the observer actually sees as the sun rise/set. The following complication families are supported: Modular Small,  Modular Large,  Utilitarian Large, Utilitarian Small Flat,  Extra Large,  Graphic Corner, Graphic Bezel, Graphic Rectangle, and Graphic Extra Large. Add the Sun Rise/Set complication to your watch as you would any other Apple Watch complication. - Other, non visible improvements.

Version 8.11(2) - Added the ability to start, stop, clear, and save tracks from the CourseSpeedWatch App. - Added current track distance field to the CourseSpeedWatch App. - Changed when track history points get stored from a time base to a distance base. - Made changes to the speed and course computations when the GPS receiver gives a position update but not a valid speed or course update (i.e., compute speed and course from the last two valid measurement lat/lon positions). - Other, non-visible, improvements.

Version 8.10(4) - Changed the commands to Apple's Location Manager that provides the GPS receiver position updates. In previous builds, the App was requesting every location update (which occurred every second). Changed the Location Manager commands such that it now sends position updates whenever the iPhone moves more then 3.6 meters (12 Feet). This eliminates the problem of receiving position updates when stopped that actually indicate that you are moving (speed non-zero). - Changed the Speed and Course smoothing "Alpha" values due to the changes to the Location Manager settings. - Updated units conversion constants to contain more fractional digits for more accuracy. - Disabled the Map View periodic timer when the Map View is no longer visible and no track is in progress. - Other internal, non-visible, improvements. - In the CourseSpeedWatch App, changed the "Getting Data" indication to "Synching" whenever the watch is waiting for data from the CourseSpeed iPhone App.

Version 8.9(11) - Added Trip Odometer buttons to the CourseSpeedWatch App to Start, Stop, Pause and Reset the Trip Odometers. The functionality is identical with that on the iPhone App but now more convenient. - Corrected the Trip Odometer state colors on the CourseSpeedWatch App to match the colors on the CourseSpeed iPhone App. - Made the Trip Odometer units part of the value field. Units abbreviations are: MI, NM, or KM. (Miles, Nautical Miles, Kilometers). Removed the previously separate odometer distance units text line. - When the Watch App is waiting for the iPhone App to provide data, e.g., at startup of the iPhone App or when the Watch App becomes active (visible) again, now writing "Getting Data" to the watch display fields.

Version 8.8(5) - Made the location horizontal and vertical accuracy units be in meters as well as feet (Tracks the units of distance of the currently selected speed units). - Updated the CourseSpeedWatch App for the Location Accuracy units change in the iPhone App. - Fixed an issue with the trip odometers in which the first point used in determining the distance between points is from an earlier time for which the location is not the location where the odometer was started. This may have given the odometer an immediate error, potentially miles.

Version 8.7(2) - Fixed an issue with a change made to the previous build that caused the trip odometers to be twice what the actual distance is. - Fixed an issue when the user returns to the Map view where the current track history was not being redisplayed on the map under certain conditions. - Fixed an issue which caused the map position center to move about when regular updates are not being received from the GPS receiver and the speed is near zero.

Version 8.6(9) - Made internal improvements to the communication between the CourseSpeed iPhone App and a connected Apple watch running the CourseSpeedWatch App. - Enabled the iPhone to determine whether it needs to run, or not, in the background using the iPhone GPS receiver in order to support the watch App. - Changed the way the trip odometer increments the distance traveled every position update for speeds near zero and with poor GPS coverage. - In the main view, selecting one of the buttons to change the units of a data item will now immediately convert the data field value to the new units instead of waiting for a new position update. - See note in the CourseSpeed iPhone App "About" text in the Trip Odometer section for a note indicating when the iPhone GPS is being used for each Trip Odometer state. This becomes more important when using the CourseSpeedWatch app.

Version 8.5(2) - When the "Mark" is active, and the iPhone App selected speed is "Speed Made Good", set the Watch App speed label as "Speed Made Good". - On the Watch app, split both horizontal and Vertical Accuracy data fields into a data field and a units field. (previously the data and units were all one field) This was done in order to have the units field a different color than the data field. - Made the Watch App units fields a different color than the label/data fields. - For the Watch App, changed horizontal/Vertical alignment attributes for new units fields to be left/center. - For the iPhone App, made the Speed field minimum size smaller for smaller iPhones and km/hr speed units.

Version 8.4(0) - Shortened the field names Sun Azimuth and Sun Elevation to Sun Azim and Sun Elev on the CourseSpeedWatch app to avoid truncating their respective values on a 38mm Apple Watch. - Increased the CourseSpeedWatch App's time as the "frontmost" App to 8 minutes.

Version 8.3(0) - Added the following fields to the CourseSpeedWatch App:  GPS Horizontal Accuracy, GPS Vertical Accuracy, Sun Azimuth, and Sun Elevation. - Added the units of each watch field (e.g. MPH)  Note: The units reflect those that have been selected in the CourseSpeed iPhone app.

Version 8.2(1)f - Added "No Data" text in each watch data field when data has not been received from the iPhone within the last seven seconds. - Fixed the Trip odometer auto-pause color such that it is the same magenta color as in the watch app.

Version 8.1(3) - Added a button to show/hide the "About" information for the CourseSpeedWatch App. - Made the CourseSpeedWatch App automatically start the CourseSpeed iPhone App if the watch App is started without the iPhone App already running. When started this way, the CourseSpeed iPhone App will run in the "Background" mode to provide the data to the watch App. You can bring the iPhone App to the foreground at any time by pressing the blue highlighted Time field on a newer iPhone (with a notch) or by pressing the very top, blue, line of an earlier iPhone. Don't forget to terminate both the iPhone App and the watch App when no longer in use to save resources (e.g. battery). - Added Trip 1 & Trip 2 state colors to the values in the CourseSpeedWatch App that match the colors on the iPhone App. (Inactive: White; Active: Green; Manually Paused: Orange; Automatically Paused: Purple) - Added a CourseSpeedWatch App version string separate from the iPhone App's version string. If the versions don't match, the CourseSpeedWatch App will present the version in Red.

Version 8.0(10) - Made the entry of a "Speed-Made-Good" Mark and "Point of Interest" entry on the Map View mutually exclusive. i.e., hide the button of one when the other button action is active. - Added text on the Map View Map whenever an Add POI or Add Mark is being processed. Each is a reminder to the user that the respective Add is still active and the user should complete the action. - Created an Apple Watch App "CourseSpeedWatch" that is now available for use with a paired iPhone running the CourseSpeed App. The CourseSpeedWatch App functionality is a subset of the iPhone App and contains only data fields with no controls via buttons. The CourseSpeedWatch App requires an Apple Watch running watchOS V5.0 or later. The following data fields are visible on a single, scrolling, screen: 1 Position (Latitude & Longitude) 2 Course 3 Speed 4 Altitude 5 Trip 1 Odometer 6 Trip 2 Odometer 7 Distance to a user entered Mark 8 Bearing to a user entered Mark 9 Sunrise time 10 Sunset time
