Bingo Card Creator is pretty firmly EOLed. Sales YTD this year are about $30k, probably $35k all-in for the year. Profits are stable at about 60% unless I miss my guess. This is down substantially from previous years, partly as a result of Google changes which I haven't made the least bit of effort into looking into. Also have ~$1k a month from books/courses, and hoping to get out another course before the end of the year, if life cooperates.
My main gig these days is Appointment Reminder. I'd describe it as "modestly successful." (A single signup for the largest publicly available plan is, probabilistically, worth more than BCC made in its best months. Historically, that has only received about as much sales effort as BCC clients got -- i.e. nil -- but I'm experimenting with having active inside sales starting this week.)
