Navionics discrepancies

[dubob]

I wonder if you have found the Navionics topo maps accurate. 
I intend to buy the app this year but am not sure the online maps are accurate. 
I have covered willard pretty good but not happy with them. I have also looked at jordanelle and deer creek. And do not see the same on my Garmin finder.  I looked at starvation one day and was happy with the online map it matched my finder good.
What's your experience?

I use the phone app for ice fishing only and it has been money well spent is my experience. Most of the reservoirs I ice fish on have contour maps that consistently put me on perch. There are better apps for hunting activities, and I would use them if I still big game hunted. For soft water fishing, I wouldn't be without my Lowrance with the Navionics chip installed. I have no problems with the Navionics phone app and will gladly pay the annual $15 fee to use it.
