This is my weekend project this week, ha. I'm reading Checklist Manifesto and decided there wasn't any good app for it. I'll post back here when it's done.
Checklist templates that repeat based on day of week; auto-archive after X days. Tools for organization into groups, subgroups, etc. A way to view completion over time.
I use it for daily things (daily autocreate, daily autoarchive), weekly things, monthly things, and things I do in order but without a set time (manual creation and... autocreation after completion? no i dont think that's a feature).
Wonderful app for implementing checklists and it's a cornerstone is my toolbox for making sure I'm living my life with intension.
Yet, it's long abandoned and I dont know if it's still for sale in the app store. Probably made little money in a sea of Todo apps.
