-**A new event from Quick Settings.** Drop a KashCal tile next to your flashlight and Wi-Fi toggles. Pull down from the top of the screen, tap it, and you're typing a new event, even over whatever app you were in. The fastest way to catch a plan before it slips.
17
-
-**Plain-language events.** Type "Yoga every Tuesday 7am at the studio" and it becomes a real recurring event, with the time, the place, the repeat, and the title each landing where they belong.
18
-
-**Share an event as a card.** One tap turns any event into a designed card and a tap-to-add file, sent together in any chat. Your friend taps once to drop it on their own calendar. No screenshots to retype, no invite that drags in extra apps.
19
-
-**Real CalDAV, out of the box.** Nextcloud, Radicale, Fastmail, Baikal, Zoho, SOGo, Stalwart, and more, syncing two ways with no middleware app, no relay server, and no second thing to install. Your phone's Google and Outlook calendars ride along too.
20
-
-**iCloud on Android.** Sign in once and your iCloud calendars sync both ways, shared family calendars included. No bridge, no export-import dance.
21
-
-**Time insights, on-device.** Busiest day, meeting-free days, weekend load, your next free block. It works the numbers out on your phone, no work account and no cloud crunching your schedule.
22

-**Six views, your way.** Month, agenda, three-day, week, month-full, and year. Pinch to zoom, drag to reschedule, and color any event from a curated palette or the full color wheel.

Your calendar is the nosiest app on your phone. It knows about the dentist, the interview you told nobody about, and the event you just labeled "lunch??". It is a diary that schedules your life.

19

It is also the app that is wide open when you hand your unlocked phone to a friend to "just look at the photo."
20

KashCal now has **App lock**. Turn it on, and opening the app throws up a curtain.
Flip it on in Settings and your next open is a lock screen, not your week. Unlock with **fingerprint, face, or your PIN**. No new password to invent, no "please create a 6 digit KashCal code." Your phone already knows how to check it is you. We just ask it to.

It is one more way KashCal stays [private by default](/docs/privacy/overview): no account, no trackers, and now a lock on the door. [Here is how App lock works](/docs/features/app-lock).
