Is there an Android application for keeping a to-do list with full synchronization with Google services?

Question

Google

Good day to all, dear friends!
Once again, I was puzzled by finding the right ToDo list for my Android phone. Such applications in the Play Store are not only dark, but the following functions are of interest:
1. FULL sheet integration into Google services (Google Calendar\Google Keep\Google Now). In a nutshell: the task of the sheet is only to collect tasks and show them together, but store them in Google services. Thus, tasks and reminders are automatically fished out by Google Now and shown on cards with references to time / place. Ideally, the program should not have its own cloud at all (as Wunderlist, LeaderTask, etc. do).
2. Ability to create tree-like tasks with subtasks, with subsubtasks, etc.
It is desirable that the application has the following features, but not required:
1. Desktop client for Windows\Chrome extension.
2. Rigid GTD structure.
Below is a list of programs that I have tried:
- Wunderlist. Own cloud, no synchronization with Google.
- LeaderTask. Own cloud, no synchronization with Google, unusable Android application.
- Asana. Most suitable, but: own cloud, syncing with Google Calendar only tasks with a hard date
- GTasks, Tasks and others using Google Tasks. Google Task is not picked up by Google Now, respectively, there are no reminders or other goodies; no geolocation.
I've been looking all day today for something like this and can't find it. The main problem is with the first requirement. I really hope for your help.

Answer 6

I am also interested in this question. Ideally, to be able to bind the task (event) not only to time, but also to the place (not "OR", namely "AND").
At the moment, I know only one program - aCalendar + Calendar & Tasks (paid version only). But the to-do list and the calendar widget are not very good there. In general, not quite what you are looking for. But he might take a look.
Until I get used to it. And so... I use Gtasks for tasks, and DigiCal for the calendar (I really like its "List" widget).
Did you find any solution?
