I believe Taskos [play.google.com] is a a great way to sync with Google Tasks. I usually suggest this to my customers when for any reasons they need to an alternative to the otherwise excellent Gtasks [play.google.com].
Taskos has a clean and handy interface, and it’s usually quite bug-free. So I was quite surprised when one client I referred to Taskos went back to me complaining that he could not find the Menu-settings on his HTC One SV (Cricket) [htc.com].
I must admit I was quite baffled when, I too, was not able to find the Settings Menu, not a graphic button at least. What is it?
A quick google search confirmed my suspicion. The HTC One HAS a menu button, and it’s in plain view.
GTasks comes also in a premium flavour, for a little fee [play.google.com].
Disclosure: to date, I have no business with the Taskos team or with GTasks team.
