I actually have a twillio + python SMS setup on a VPS that's extremely reliable, but haven't designed a better interface besides cron which is less than ideal.
It just runs all the time on my laptop. Every day at 9 it checks a sqlite3 database to see if there are tasks for the day. That's running in a thread.
The main process has a little interface with a menu that lets you input a task, view tasks, search for tasks by text string, etc. (I did do some work on it; it wasn't just a 10-minute project! But what the heck, I've needed something that would solve me problem for decades and nothing I found in the marketplace worked (for me)!)
I'm thinking of making a web interface and allowing other people to use it.
