I know you are sick of this trite task manager apps, there are a lot of them. Here untold numbers of them.
But I want to suggest you something new, something that I am using by myself.
Meet, GTT - geo-timed task manager!
* add time to your task to know how much do you have before if will be expired
* add location and run the tasks that are close to you at the moment
* add notes to your task
This is beta version, so please, don't leave bad feedbacks. If I will see your interest to GTT, I will develop it.
You can contact me if you like to add some features. You can help developing this project this way.
