Lake map apps for I phone

New to Texas lakes and the forum any one know of a good app for topo maps for lakes here in Texas?

Navionics

I've used SL Huntinf app for iPhone

Your able to load a water contour overlay.

Navionics is the only way to go. Bought 3-4yrs ago and still use today. You can't go wrong! Marking waypoints,sharing and the GPS is awesome! I used it last week to stay in river channel in shallow water. If you bank fish,you can mark spots that were good so you can remember where and when you catch fish there. Very nice app

I agree with navionics! It's a solid app and it's like having a lowrance unit in your hand. Very accurate. It does cost money though. Another app that you could use is Fishidy. it's a free app, has contours, and hints from other people that have fished there before. Probably the best free option I've found.

Thanks for the input

Again for navionics......

I like to use Navionics on my I-pad when at home or at the office. Gives you a chance to scout somethings while off the lake. Have not noticed much of a difference when getting in the boat with the Lakemaster map. I have run both side by side.

The Navionics APP is a great tool for Smart Phones or Tablets as well as the Navionics Free Web App on your PC. Both are updated with all the latest updated mapping from Navionics.
