  • Great App Nov 5, 2020

    By Nvrbeen2fast
    For what this app is & does is a solid value for 1.99. I’m a professional land surveyor working as part of a large organization. This app lets me empower people who know next to nothing about surveying but can reliably follow instructions on converting their waypoints for “x” into state plane coordinates or to lat/long as needed. With the GPS enabled, they can hover over something for a few seconds to get a decent “fix” & then copy that data to their clipboard to place in another app or wherever they want to store it. For anyone who feels the app doesn’t perfectly translate between datums, please understand that the world isn't a perfect geometric figure & the mathematical models do their best to approximate but errors will occur relative to source data & datum as well as the output. That shouldn’t reflect negatively against the app but it’s merely how the process of translation & rotation of data between datums works. However, tapping on a field to enter coordinates causes the screen to scroll up beyond what the user can see. So you can’t copy/paste values for easy conversion. This is a pain. 11/04/2020: New update did indeed fix screen issue I was experiencing. Thank you.

    It's a great app. The only defect which made me to give it 4 stars, is the old gingerbread era GUI design. If it's not make too trouble, dear developers please concern the material design guidelines in new user interface.

    Very informative, and I would be grateful if it could show UTM grid coordinates of Northing and Easting, in addition to geodetic coordinates of latitude and longitude.

    This is the only android app I've ever found that can compute UTM grid convergence (for setting your compass to grid declination, for paper-map navigation). The UX isn't perfect, but IMHO it definitely deserves all 5 stars for having that one critical feature.

    Since App obtains coordinates from GPS, It would be better if coordinates can be saved in a file instead of copying to clip board.

    Just bought the app and used it on a jobsite (I'm mapping geology on it). Really simple to use and just what I needed.  Instant state plane coordinates that I can use directly on my field maps. I should add that the conversions can be nearly real time if you use your phone's gps.
