You can check your Apex Legends Characters Online Profile, Stats and Rankings via this site called https://apex.tracker.gg. It's an awesome site, where you can just enter your character name and then choose a platform, whether you're playing on PC, PS4 or Xbox One. Don't be alarmed if you don't see any of your characters or stats on your online profile page because you have to actually click on the Add Legend button and then the Force Update button.
Before that, you will need to actually manually, have that particular legend sitting at the lobby in-game. Click on Legends, choose the legend and set the stats you wish to display by clicking on the Banner Tab. Once you've chosen your stats, just click back until you're at the lobby. Then, go to the site, and click on Add Legend then Force Update. You have to do this repeatedly for all the characters that you wish to be published publicly online. You can also use this site to search for your friends and famous streamers, just to see their online stats
Take note, that the site is still in its Alpha stage and most of the features such as weapon kills, match statistics and others are still in progress which the developers will be updating soon in the near future. Be sure to follow the devs on Twitter at @Apex_Tracker.
