CoordCalc vs Sea Depth

A coordinate utility app that calculates the distance and initial/final bearings between two points on Earth specified either manually by latitude and longitude or automatically using the built-in map. It can also calculate a final position given an initial position, distance, and bearing. ################################ Limited time sale, get it now before the price increase to $4.99 ################################ The final distance can be calculated in miles, kilometers, nautical miles, yards, meters, or feet. Coordinates can be specified in and converted to and from decimal degrees, decimal minutes or decimal seconds. Bearing is returned in degrees true. Uses WGS84 for improved great circle distance calculation accuracy. NOTES: Coordinate messages can only be sent to other CoordCalc users and are available only within the app. Additional Features: -Can use internal GPS to find the lat/lon coordinates of your current location -Can use and drag the points around on the built-in map and get distance/bearing updates continuously. -Shows starting and ending positions on a map -Saves the previous set of starting and ending positions -Maps can display satellite imagery, and labeled roads, highways, cities, oceans, etc. -Can send coordinate messages with short notes to other CoordCalc users. - Built-in HD version for iPad Example use cases: -Navigation tool for aircraft, boats, etc. -Measure walking distance -Finding your exact position in order to mark points of interest/landmarks or meeting places. -Visualize and edit starting and ending locations using the map feature. -Calculate the size of various landmarks if they are visible via satellite. -Save the position of your parked car -Convert coordinates between different formats Checkout the revamped website and video at: www.justintimeapps.com iOS 4.0 Tested A video demo of how to move the pins is located here: http://www.justintimeapps.com/ts.html This pin jumping issue has been fixed in iOS 4.0, but for iOS 3.0 users, the difficulty of this depends alot on your screen protector. If the protector has a rough surface and causes your finger to jump around, the pin will be dropped often. You will get a better response if you move your finger slowly. Although, you should still be able to move a pin from the top to the bottom of the screen within 2 seconds without losing track. In iOS 4.0, this is not an issue.

SeaDepth delivers professional-grade bathymetric charts for anglers looking to add a new level of detail and insight offshore. Built using high-resolution survey data and advanced shaded-relief techniques, SeaDepth reveals underwater structure, contours, and terrain that traditional charts often fail to show. The result is a clearer, more intuitive view of the seafloor - helping anglers and captains better understand offshore environments before and during time on the water. In addition to detailed depth visualization, SeaDepth offers optional data overlays, intelligent contour labeling, waypoint interoperability, and analytical tools that enhance situational awareness offshore. Key Features • High-resolution shaded-relief bathymetry • Detailed, clearly labeled depth contours • Intelligent contour interval scaling by depth range • Pipeline overlay (Gulf of America) • Bottom composition overlays highlighting seafloor characteristics • GPX waypoint import and export for interoperability with other platforms • Drift Test tool to observe drift direction and speed over time • Offline chart access for use beyond cellular coverage • Smooth zooming and panning optimized for offshore use Depth Contours with Intelligent Labeling SeaDepth uses a graduated contour labeling scheme designed to provide maximum detail where it matters most, while maintaining clarity and performance in deeper  depths: • 1-foot contour intervals from 1 to 500 feet • 10-foot contour intervals from 500 to 2,500 feet • 80-foot contour intervals from 2,500 feet to abyssal depths This approach delivers high-resolution insight in shallow and mid-depth areas while avoiding visual clutter in deepwater environments. Overlay Intelligence SeaDepth allows users to enable optional overlay layers such as pipelines and bottom composition data in supported regions, including the Gulf of America. These overlays provide additional context and help users interpret bottom features and structural edges with greater confidence. All available overlay layers are included at no additional charge. Waypoint Management (GPX Support) SeaDepth supports importing and exporting waypoints using the GPX file format, making it easy to move data between SeaDepth and other compatible marine devices, charting software, or planning tools. This allows users to maintain consistent waypoint libraries across platforms. SeaDrift-Drift Test Feature The built-in Drift Test feature helps users evaluate drift behavior by tracking movement over time. This is especially useful when assessing current and wind influence to have more productive drifts. Built for Offshore Reliability Charts, overlays, and waypoint data are stored locally on the device, allowing SeaDepth to function reliably offshore where connectivity may be limited or unavailable. Performance and usability are optimized for real-world offshore conditions. Disclaimer SeaDepth is intended as a supplemental planning and visualization tool only. It is not a substitute for official nautical charts, onboard navigation systems, or prudent seamanship. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
