everyone will tell you that it's a fool's errand to make your own todo app, or to make any app for yourself, it's just too expensive when you can get a 'better' one 'off the shelf' or when you can get equivalent functionality from separate tools. i think this is probably technically true for the food i make as well, but the deltas in time required are so different. Even a really talented developer can only get so far in an afternoon or day and the alternatives to diy'ing are so much more compelling: a todo list on paper, the system reminders app, whatever. I know that the adages are as much about cost effectiveness as they are balancing technical skill and executive function, but it's also weird that we tell people: this skill you have honed, save that for the office, amigx.
