I hate to be all "Simpsons did it!," but you can do a lot of the same stuff with Twitter using Remember the Milk. Still, I think your app would be a more appealing option to people who just want to set reminders via Twitter and don't want an entire task management program to deal with. Good job!
It's unclear from the front page what type of reminders I can actually set.
You give a lot of examples as to what will be supported in the future, but I can't tell what is actually supported now.
I'm trying it out anyway, but it would be nice to know those things without testing. : D
Cute. Is there a way to see my reminders or manage them? I was thinking of doing something like this but using a Jabber bot awhile ago but never got around to it. I think that would be a good interface for something like this.
Nothing personal, but I think there's a lot of trust involved in things like reminders, calendars, to-do lists, etc. Having a bad experience like this with my first try makes it much less likely that I'll give it another go.
What problem is this specifically solving that dozens of other scheduling/task/GTD/Calendar systems haven't solved?. Even the most basic phone now has some kind of alerting feature on it.
It's usually a bit of a hassle to set those, since you have to set each of the fields and most date fields are rather annoying. Just using plain text is easier.
