Create and send Appointment-Confirmation-Message from Android-Calendar-Entry.
About this app
Making an appointment means
• Add date, time and title of the appointment to the Android-Calendar
• In Android-Calendar-Detailview use Send/Share (from menu or toolbar)
• Select "CalEF" as share destination (to convert to human readable text)
• Select the final Send/Share destination (clipboard, sms, mail, ...)
Usually calendar entries are shared in a human-unreadable technical format "ICS" (or "VCS") that calendar programs can read.
CalEF receives the technical format and re-sends/re-shares it-s content as human readable text.
Date/Time is formatted according to current language/locale.
CalEF can also process "ics" (or "vcs") files (i.e. from a calendar backup).
Requirements:
• Android-4.4 (api 19) or later.
• Permissions : None
Compatible with
• Etar-Calendar version 1.0.29 or later (January 2022)

Installation Guide
Open Settings on your Android device
Go to Security → Unknown sources (or Install unknown apps)

Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be de.k3b.android.calef is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.1.2 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall CalEF (Calendar Entry Formatter) first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of CalEF (Calendar Entry Formatter), and a listing is removed when the evidence for it stops holding up.
