Its a to do list that can go everywhere with you and no writing! Can prioritize list as well great little app 11/2019 edit- hoping like other folks that they undo the changes. This app has gotten more difficult and counterintuitive with the last update. Used to be able to select multiple items to reschedule at one time. Can't do that anymore. Also used to be able to just type repeat everyday, repeat every Monday Wednesday and Friday etc. It now seems like only sometimes that works.
