As much as it’d be nice to have a general solution that fixes this… I think that anybody wanting to be reminded to enter data on a daily goal at a certain time would be better off, um, setting a reminder. i.e. in a reminder or clock or calendar app, rather than trying to get Beeminder to do this.
The other reason that I like this out-of-band solution is that I don’t want a gazillion reminders to enter data on each of my gazillion goals. One scheduled reminder to enter today’s data will be quite enough.
The special case where Beeminder excels is in sending zeno notifications on emergency days.
