Calendars by Readdle
An app that puts your calendars, tasks and habits in one place.
What Calendars by Readdle does
Calendars by Readdle is a calendar and planner for Apple devices. It pulls your Google, iCloud and Outlook calendars into one place, adds tasks and habit tracking, and lets you type events in plain language. A basic calendar is free, and PRO adds the planner extras.
Calendars is a polished calendar for people who live on Apple devices. You connect your existing accounts, like Google and iCloud, and see everything in day, week, month or agenda views with color coding. With PRO, you can type something like "lunch with Sam Friday at 1" and it turns into an event.
It goes a step past a plain calendar. You can keep a to-do list next to your events, build routines and track habits, and join Zoom or Google Meet calls straight from an event. Widgets put your day on the home screen, and the app runs on iPhone, iPad, Mac and Apple Watch, so your plan follows you around.
It isn't a family calendar app. Calendars shows the calendars you already share through Google or iCloud, but it doesn't have its own family sharing, shared lists or chores. Think of it as a nicer front end for the calendars you already use.
There's no Android or web version, so it only makes sense if you're all-in on Apple.
