KoraCal keeps your calendar for you. Email becomes events and tasks. Plans stay current. Your agenda, calendar, and task list all stay up to date. THE EMAIL BECOMES THE EVENT A coach’s practice note lands as a calendar event — time, place, and title — not a form you fill in. A cancelled dinner or a moved pickup updates the event. You don’t hunt down the old one. TASKS FROM YOUR EMAIL INBOX Things you need to do become tasks: wash the car, return the permission slip. Undated to-dos live in lists you organize. Dated items show on Agenda and on Calendar (day, week, and month). CREATE, EDIT, AND SHARE Add or fix an event or task by typing, by voice, or on the calendar grid. Group chores into lists. Share your calendar with a partner or assistant so pickups and practices stay aligned — without forwarding threads. ON IPHONE • Say “Talk to KoraCal” or “Ask KoraCal” to open Voice • Import Apple Calendar events you choose • Import Apple Reminders lists as KoraCal task lists • Type or paste a note, screenshot, or confirmation and KoraCal turns it into events and tasks HOW IT WORKS Connect Google mail and calendars, plus the Apple calendars you choose. New messages become events and tasks; replies update them; other calendars sync in the background. You open Agenda, Tasks, or Calendar — with reminders already attached. READ-ONLY CONNECTIONS KoraCal connects with read-only access. It cannot send email or change anything in your Google or Apple accounts. Your data is not sold or used for ads. Sign in with Google or Apple. Privacy policy: https://koracal.ai/privacy Support: admin@koracal.ai Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is rating: Calendars at 4.7 against KoraCal's 3.7. Calendars also leads on ratings volume (123K vs 3) and chart position (#106 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Calendars sells 10 in-app purchases, starting at $3.99 per month and KoraCal sells 1 in-app purchase, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.
Calendars holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: Calendars has 123K ratings behind it against 3, so its average is the more settled of the two.
