From Mike Irving:
Designed for Professional Workers in Ireland (Republic of Ireland and Northern Ireland), who use the Irish National Grid Reference System.Lookup your current location in Irish Grid Ref, OSGB36 or WGS84 GPS formats. Find your current Compass Bearing, and find out the Accuracy (in Metres) of the GPS data.Send this information back to base via Email, with an Optional Photo. (Take a new photo or choose existing from library) *The Email Subject and Email Text can be customised and saved from the Settings Tab. Once set, your customised text will be used for each new Email message.Simplified information can also be sent via Text Message / iMessage or as a Twitter "Tweet". *Includes a handy graphical guide to the Irish "National Grid" system.Whilst the app will work worldwide, the values given will only be of use within The Republic of Ireland or Northern Ireland (United Kingdom).For the best accuracy, use in an open space, away from trees or hill edges.Like a traditional compass, use with the phone in a flat position, not upright.When continued usage is required, you can set the iPhone Screen to stay on indefinitely, from the Settings tab.This app requires Location Services to be enabled in your iPhone, and you must grant permission to the app to use these.Compatible with iPhone 3GS, or newer. Not compatible with iPod Touch, iPad, or earlier iPhones (due to the lack of GPS and Compass hardware).* - Internet Connection, and correctly configured Text Message (or iMessage), Email and / or Twitter settings, required to fulfill. Twitter functionality only available in iOS5, or later.
