GS305 Unmanaged switch app

   I doubt it.  A GS305v2 is an unmanaged network switch.  You don't
need any app to do anything with it; there's very little which you could
do with it, with or without an app.  You simply connect Ethernet cables
to it and watch the pretty LED indicators.

   I agree.

   "all of" _which_ "the apps"?

   "Didn't work" is not a useful problem description.  It does not say
what you did.  It does not say what happened when you did it.  As usual,
showing actual actions (commands) with their actual results (error
messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations.

   What, exactly, are you trying to do?  Have you some kind of Internet
service?  A modem?  A router?  Why did you get a GS305v2?  Is there some
actual problem which you are trying to solve?

   General advice: You might have more success if you described
(clearly) the actual problem which you are trying to solve, rather than
asking how to implement some particular "solution" ("what app") which
may have little or nothing to do with the actual problem (whatever it
might be).
