Average bulk plate motion is about one inch a year. Fastest plate boundaries move about four times that. So on the the surface this would be well within the error of mobile device GPS. A major exception would be major geomorphic events like magnitude 7+ earthquake (10s of feet), landslide, river jumping its banks (like before the Mississippi was channelized). Then maps and property titles may need to account for this. In practice, plates are not rigid masses. There are internal differential lateral motions of millimeters a year, or in most cases an order of magnitude slower than plate tectonics. There is a branch of geophysics called dynamic geodesy which teases such precise measurements from more coarse GNSS (GPS is one of six national GNSS). Such motions study pre-earthquake fault strain, pre-eruption swelling of volcanoes, man-made or natural injection/extraction of various subsurface fluids.
