The date time used by the Global Positioning System (GPS) is normally expressed as a week number and a seconds-of-week. This software can convert the GPS week-seconds format into the equivalent local date time and UTC date time, and vice-versa.

Polar Scope Align

Polar Scope Align will calculate the position of Polaris or Octantis in your Polar Scope reticle for your location (using your phones GPS), allowing a quick and accurate polar alignment. It is one of the few programs that are accurate even in lower latitudes by correcting for atmospheric refraction (so expect results to agree only with precise software and not most simplistic polar align apps - see the Accuracy section in the website). The main reason for this is that while I intend to keep support for iOS 6/7 devices for as long as I am allowed, even for very few users, it adds an overhead so I should make sure it is really needed.

Emerald Timestamp

Emerald Timestamp captures the precise time of events, and lets you associate a description with each one. It is also a highly-accurate running clock. Like all other iOS apps, Emerald Timestamp cannot set the devices internal clock.)

Polar Scope Align Pro

Please note that the only in-app purchases available are tips. All functionality is included. The main reason for this is that while I intend to keep support for iOS 6/7 devices for as long as I am allowed, even for very few users, it adds an overhead so I should make sure it is really needed.

Emerald Time

Emerald Time uses Network Time Protocol to display the current time of day as defined by the international standard atomic clocks. Its accuracy is limited only by network latency and is usually accurate to less than +/-100 milliseconds. Emerald Time does not change the internal clock used by all other iPhone apps.)

Official US Time

Ever wanted to know the most exact of exact times? Makrr brings you the answer with the The Official U.S. Time app, powered by the NIST, USNO, and time.gov. We do not guarantee accuracy and this should not be used to establish traceability to the NIST or USNO.
