Take the 2-minute tour ×  i want some example for the best
application/client for manage and edit and control your Google
calendar and daily mission or event.  and it provide alert
-alert with sound or notification- to give you more attention
for your important work ?  share|improve this question Just use
the defualt google calendar browser-based offline app and extend
it with a sound plugin an that's it... and btw if there's no app
does that mean that the OS has restrictions or does that mean
that people where too lazy to program one. Just program one by
yourself and share it with people like you. –  mash Nov 3 '12 at

Answers 3  up vote 3 down vote accepted  According to this
thread. Mozilla Sunbird with the GCALDaemon is what you're
looking for. But I believe development is going to be stopped on
sunbird, so maybe Thunderbird with the Lightning calendar addon
might be best.  share|improve this answer  Here i suggest
Sunbird is your the best app
