This page is designed to help you find out whether Callvent.app is good and if it is the right choice for you.
Callvent is a call logging app for iPhone, Android, and Wear OS that turns your phone calls into calendar entries.
When a call ends, Callvent shows a notification with the call duration. One tap saves it to your calendar; open the full view to add a contact, notes, tags, and a callback reminder.
It works with regular phone calls as well as WhatsApp, FaceTime, Telegram, Signal, Microsoft Teams, Zoom, and other apps built on CallKit. Entries go into any calendar you already use — iCloud, CalDAV, Exchange, or Google Calendar.
Other features: - One-tap Quick Save from the notification - Tags and notes (Business, Personal, Important, Follow Up) - Callback reminders (15 min, 1 hour, tomorrow morning) - Caller ID from your contacts - Statistics about your call patterns - Home screen widget and Siri Shortcuts
All data stays on your device: no account, no cloud sync, no tracking, and no third-party analytics. Free to download with a 7-day trial of all features, then monthly, yearly, and lifetime plans.

Callvent was built by mittl medien, an independent developer studio, out of a simple frustration: calls happen all day, but the details — what was agreed, who to call back, when — slip away the moment you hang up. The existing options meant opening a CRM or typing everything by hand. Callvent's idea was to make documenting a call as fast as dismissing a notification, and to keep the result in the calendar people already live in — on the device, not in someone else's cloud.
Callvent turns every phone call into a calendar entry instead of a CRM record. When a call ends, it shows a notification with the duration, and one tap saves it to the calendar you already use — together with the contact, notes, tags, and a callback reminder. It detects incoming, outgoing, and missed calls automatically and also works with WhatsApp, FaceTime, Telegram, Signal, Microsoft Teams, Zoom, and any other CallKit app. Everything stays on the device: no account, no cloud sync, and no third-party analytics. It even runs standalone on Apple Watch and Wear OS.
Most alternatives are personal CRMs that ask you to keep records in a separate app and sync them to the cloud. Callvent is lighter: it logs calls into the calendar you already check every day, needs no account, and keeps all data on your device. You can document a call in about ten seconds straight from the post-call notification, set callback reminders, and organize calls with tags and notes — without the overhead or monthly lock-in of a CRM. Pricing is modest and includes a one-time Lifetime option, with native apps for iPhone, iPad, Apple Watch, Android, and Wear OS.
People who make a lot of calls and need a record of them without running a full CRM: freelancers, consultants, sales and account managers, lawyers, real-estate agents, recruiters, and support staff. In short, anyone for whom "what did we discuss, and when do I follow up?" matters every day.
Callvent is built natively for each platform, with all processing on the device and no shared backend. - iPhone, iPad & Apple Watch: Swift and SwiftUI — CallKit for call detection, EventKit for calendar integration, WidgetKit for the home-screen widget, App Intents for Siri Shortcuts, WatchKit for the watch app, and StoreKit for subscriptions. - Android & Wear OS: Kotlin with Jetpack Compose (and Glance for widgets) — the Telephony APIs for call detection, CalendarContract for calendar integration, and Google Play Billing for purchases.
