Things that intercept links (like if you go to a link that has tapatalk enabled, it will see that and open tapatalk instead if you want it to, or if you click a reddit link and you have reddit is fun installed, it will open in the app instead of the browser) need to open at startup, or else they won't work correctly.
Why does it matter if your phone starts up a few seconds/minutes quicker? If your phone REALLY took 6 minutes to start up, you must be having issues or you have an old phone or something. Mine starts in 31 seconds (according to the app you listed up top) with the following apps coming up at startup: gmail, groupon, k-9 mail, maps, mybackup pro, pandora, reddit is fun, rom manager, screenshot it, startup manager, superuser, tapatalk, the weather channel, youtube, and zedge. This is not including system apps.
Maybe you had tons more than I do but I just don't see how potentially screwing up functionality of the phone is worth a few extra seconds or minutes of your day.
I am going to keep this app installed cause it does have some cool features, so I appreciate you telling us about it.
