On top of that, we have a new parent company: Oceaneering International, Inc. Because of this, we've changed some colors and created a new logo. We also thought a new name was appropriate. The first major change is that we are now supported on iOS10. While fixing that, we added a few user-requested datums and projections, including: - Indian 1975 Datum - Hartebeesthoek 1994 Datum / LO27 Zone - European Datum 1950 - Kentucky Single Zone (1600) for SPCS83 We have also added the ability to save any converted coordinates in a list for future reference. The list is visible from the map and can be exported via email. ### 1.1.0 — 2013-12-01 * Your converted coordinates can now be displayed on the map * You can now drop a pin on the map and get the coordinates * Need to find the closest C & C office? Simply press the C & C logo on the map and we'll take you there * Fixes the UI for 4" Retina iPhones ### 1.0.4 — 2013-11-19 Fixed a bug in iOS7 when changing geodetics ### 1.0.3 — 2012-06-13 - Fixed a bug that would not accept input in feet - Fixed a bug that wouldn't allow the user to clear the X or Y coordinates ## Apps similar to Oceanodesy | App | Rating | Price | Category | | --- | --- | --- | --- | | [SolarLunar Data](https://appshunter.io/ios/app/solarlunar-data/id6475114921) | 5.0 (1) | Free | Utilities | | [3D Interpolation](https://appshunter.io/ios/app/3d-interpolation/id1000298349) | — | $4.99 | Utilities | | [GPS Format Converter](https://appshunter.io/ios/app/gps-format-converter/id1323303352) | 4.5 (6) | $0.99 | Utilities | | [DTR v2](https://appshunter.io/ios/app/dtr-v2/id6480346108) | — | $17.99 | Utilities | | [Lat/Long Coordinate Converter](https://appshunter.io/ios/app/latlong-coordinate-converter/id6737682566) | — | Free | Utilities | | [Lat Lon Converter](https://appshunter.io/ios/app/lat-lon-converter/id889650127) | 3.0 (4) | Free | Utilities | ## More apps by Oceaneering International, Inc. - [OCEANSMART](https://appshunter.io/ios/app/oceansmart/id1511591937) - [Magnified by Oceaneering](https://appshunter.io/ios/app/magnified-by-oceaneering/id1600107058) - [Horizon-Employee Onboarding](https://appshunter.io/ios/app/horizon-employee-onboarding/id6504866639) All apps by Oceaneering International, Inc.: https://appshunter.io/developer/1262887736 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
