Poor performance

Just purchased for my new iPAD to chart and measure run routes; locked up within minutes; only does single straight line measurements, no grab and drag to move the map and keep measuring, and no map rotation. no true route mapping like on google earths PC version; if you go to options, and then go back to main display, half the screen remains white. Overall, pretty sucky app and not worth paying for.
