Overall, the app does what it's supposed to do, but a few quality of life features would go a long way - for one, a list for "later this week" would be nice, as would the ability to nest lists more than one deep. However, the Achilles' heel of the system is definitely its sync. Syncing frequently fails or takes forever, and is often too slow between devices to make the most of the other capabilities of the app. Honestly if a better option came out I'd jump ship in a heartbeat.
