Cons
Con No calendar integration
Does not have calendar integration
Con Doesn't support multiple reminders
Con Beta interface is confusing for first-timers
The interface is very opinionated (this is a good thing). But it is not obvious how to map user's own GTD variant onto the one the author has in mind. Maybe after it is in production, there will be better on-boarding.
