Amazing Marvin
(setup to mimic Things 3)
I am loving your app. I've been using Things 3 but finding that your app has all the things I was missing form Things... Very well done. It's awesome AND gorgeous!
Been using it for 3 days transitioning from Things 3 and am enthralled!
Brand new user who is a veteran of all the to-do apps, but most recently and consistently Things 3. So far, I'm entranced by Marvin. REALLY impressive work. And, love your approach.
I’m particularly excited I can leverage your app to mimic Things 3 but with much more features such as time estimates, task drag and drop into a calendar, Pomodoro and complex smart lists.
I have to congratulate you for such a piece of art, I have been using different systems and Marvin is the only one that has surprised me recently :-).
2 months into a lifetime subscription of Amazing Marvin and I can say I’m completely satisfied. Worthwhile investment in my productivity.
