When did you last change your sheets? Did you take your multivitamin today? When Did I…? lets you track when you do things so you can answer these questions and more. Choose from our suggested Actions or add your own so you can keep on top of things you’ve done. From things you do every day, to things you only do once a year, the sky’s the limit. NOT A “TO-DO LIST”: To-do list and habit trackers tell you what you should do. When Did I…? tells you what you have done and when and where you did it. ACTIONS: Choose anything you’d like to track and pick your own emoji. See how long ago it was since you last did that thing and the location of where you did it. Just tap the row when you perform that Action and When Did I…? will remember it for you. For more details about that Action, tap the arrow on the right. ACTION DETAIL: View a history of all the times you’ve logged that Action. Edit the title and choose your own emoji, add a past Event, and set up Siri Shortcuts. EVENT DETAIL: See the exact time and location of the time you performed that Action. You can add a note or edit the date and time here too. HISTORY: See your full history of all the Events you’ve added. What you’ve done today, yesterday and more. ICLOUD SYNC: When Did I…? uses iCloud to seamlessly sync your data between your iPhone and your iPad. SIRI SHORTCUTS: When Did I…? lets you add two types of Siri Shortcuts, including asking when you last did an Action and recording when you performed that Action. For example, “Hey Siri, when did I change my sheets?” Or “Hey Siri, I did change my sheets!” THEMES: Change between light or dark mode and several fun color themes.
