Personally, no. I try to keep inbox zero as often as I can. For persisted reminders, I lean on other tracking software (which is usually just Notes, my phone alarm, or my calendar).
There are a variety of apps that _assist_ you with becoming fit, wealthy, and more productive. But the app itself isn't the golden ticket. It still takes dedication, commitment, and perseverance.
I'm obviously a little biased (see the name) but I believe Dart is an excellent language to work with. Personally I prefer Angular, but I enjoyed this post. Nice work.
