re: Fishing Log/Journal apps

I keep a notebook. Granted it's only 2 years old for saltwater, but I try and snap a few pictures of some of my fish to create a time stamp. Which I can put further research into later to fine tune a spot for best tide times.

I also add baits that produced fish or strikes.

As far as gps locations, my iPhone can record that as well in picture settings. Which I manually add to my paper log.

Websites like tidesforfishing.com are great because you can backtrack to different dates and see what the tide times were as well as moon phases, weather, and those fabled projected best fishing times.
