Would appreciate your help on this, have been searching a lot to no avail.

I am looking for a single mac app that does the following (workarounds welcome!):

1. Email (2 way sync with gmail).

2. Calendar (2 way sync with google calendar)

3. Tasks (2 way sync with google tasks).

4. Agenda view (groups the days calendar events & tasks).

So basically MS Outlook but as far as I can see, this doesn't sync with google products.

I understand google released the tasks API earlier this year but there doesn't seem to be many programs/extensions taking advantage of this (i.e. thunderbird + lightning).

Many thanks
