GQueues 4+

I love this app! I use it daily, not only to manage my "to do" list but also to track other lists in various areas of my life (e.g. Long-term projects, movies/books I want to read, my Christmas card list, work goals, activity ideas for my kids, etc). I have access to all my info wherever I am, keeping me organized and on track. Easy to use. Quickly syncs and updates. Lots of customizable features, including my favorite, Smart Queues! I use my "Today & Overdue" Smart queue every day. I wouldn't know how to function without GQueues!

...this app is only part of the GQueues "system"--a todo solution integrated with gmail and gcal. It's one of the few todo apps with real, two-way syncing with google calendar. This app works great. Custom views from the web interface sync and managing tasks is great.
A couple needed improvements:
-calendar view for choosing due date (spinning wheels are terrible for choosing dates like the Friday 2 weeks from the next)
-surface the edit button after "opening" a task. Currently, it takes 3 taps to edit: tap to open, tap hamburger button, tap edit.

I've been using this app for almost 6 months and it has completely revolutionized the way I stay organized, and definitely increased my level of organization. I would highly recommend to anyone looking for something simple and straightforward, the integrates with their calendar, and has a mobile app.

I use this app every single days I can't count the amount of time this app has saved me, but it has absolutely been worth the investment.
