best google tasks manager/general tasklist app

ive tried a lot of different kinds of task managers but google tasks is just the most convenient in terms of calendar and email integration and the fact that i can see it on my laptop easily. this app is the best google tasks client on iOS...while google still hasnt put out their own. this app lets you set a default reminder time for tasks!!! i.e. my default reminder time is 5 pm the day before the task is due since im a student and this works best for me. this seems like a no brainer feature but its missing from a lot of apps ive tried before.
holding off on that last star because im still hoping for a widget for this that shows me my upcoming tasks
