Ive used Onx since day 1 and it was the best until I started using spartan forge.
Everyone likes different things and options but, for me Spartan Forge is a better app for what i like.
especially now that they have the desktop and are upgrading to uav maps and supposedly sharing all kinds info with hunting partners and even sharing live locations to friends ( "so I Hear") and a ton more features are yet to come. These are the guys who based a lot of things off of the gps collar studies using whitetails and then using that info to correlate when and where to hunt.
very interesting to me. does that work? I have no idea but its pretty cool to actually study real time locations on deer and how they move around avoiding pressure and throughout the rest of the year. Onx is great but to me it had its time and has definitely met its match.
