Mailendar turns emails, paper letters, and flyers into calendar events. The app puts that power in your pocket. SNAP A LETTER, GET AN EVENT This is the app at its best. Point the camera at the invitation from school or the flyer on the fridge, or pick a photo from your library, and we read it, pull out the date, time, and place, and file the event in the calendar you choose. No typing, no copying. (Mailendar Plus) CONFIRM EVENTS WITH ONE TAP Not every email is crystal clear, so when we are less than certain about an event we found, we ask you first. The app is where you answer. New events and updates wait in the Review tab with the original message shown next to what we filled in. Check it, tap Approve, and it goes live in your calendar. You get a push notification the moment something needs your eyes. ALL YOUR CALENDARS IN ONE PLACE A compact view of your family, work, school, and hobby calendars and their upcoming events. Edit or delete events, share a calendar as a read-only feed, or invite a co-owner who can add and update events too. WORKS WITH THE CALENDAR YOU ALREADY USE Mailendar is not another calendar to check. Every calendar is a live feed you subscribe to once from Apple Calendar, Google Calendar, Outlook, or any ICS app, and it keeps itself current. Create your free account at mailendar.app. FREE AND PLUS Free includes one calendar and 25 emails per month. Mailendar Plus adds scanning letters and flyers, unlimited calendars and emails, events from PDFs and screenshots, and co-owner invites. A Mailendar account is required to sign in.

Verdict
The clearest difference is in-app purchases: Mailendar at none against CalAction's 1. Mailendar also leads on iOS requirement (15.0 vs 26.0). CalAction's advantage is update cadence (every 2 days vs every 4 days). On price, ads and device support there is nothing between them.
