Please be sure that you follow these steps for proper installation:

  1. Delete the previous version of Nitelog from your iPhone and/or iPad. (Tap and hold the Nitelog app icon until all the icons wiggle. Press the X in the circle at the corner of the icon to delete.) Note: the past data still exists in the Z1 Auto. So it will still be there once you resync with the new app.
  2. Reboot your iPhone and/or iPad.
  3. Go to the iTunes Store and search for “Nitelog.”
  4. Install the new version of Nitelog on your iPhone/ iPad.
  5. Reconnect the iPhone/iPad to the Z1 Auto using Bluetooth. (+ sign upper left of first screen)
  6. Sync your iPhone and/or your iPad with your Z1 Auto. (Press the green circle with the circular arrow at the bottom of the chart screen.)
