Have had both onx and gohunt for yrs.
Haven’t tried downloading the onx fish app, have an android system.
One thing I absolutely love about the onx system is being able to put pics on spots with info on each spot and being able to share those. A log book and photo option would be a huge reason for me to eventually get the onx fish system. Honestly don’t care if the maps are super accurate, but relatively accurate is important on newer bodies of water would be a big plus.
The most current lake data and info would be great. Local baitstores, lodging and campgrounds would be a big help.
Current regulations, limts and slot regs for each lake would be a huge plus.
Not sure I want spots and tips, but am sure that’ll all come eventually.
Be nice to have all the trout lakes and stream info as well.
Winter kill info would be helpful for a lot of lakes.
BWCA lakes info would be great and the ability to do that without cell service like the hunt app does with being able to download areas for off line use.
Sd cards for use in electronics would be nice down the road. Or for handheld units for the bwca especially. I know everyone uses their phones now, but a fair amount still like a separate GPS units, myself included.
Good luck with the project and sure they’ll be a lot of challenges with it, but about time someone takes the challenge on and can produce a product as good as the onx hunt system for fishing.
