How do you keep important call details?
You hang up and think: “I need to remember this.” But the next call comes in, the next meeting starts – and the important details slip away.
Missed calls you forget to return
Conversations without notes that fade within hours
No record of when you spoke with whom
Callvent fixes that.
When the app catches the end of a call, it reminds you to create a calendar entry. Otherwise one tap after hanging up does it. Pick a contact, add a quick note, done.
The app automatically detects when a call ends and pre-fills the contact, time, and duration. Just add a quick note and save.
From a call to written notes in four steps.
From phone call to calendar entry – without typing a single name.
Contact and call details are pre-filled. Review the entry and save it.
Call detected
Answered, made, or missed – Callvent detects calls while the app is running. It captures time, duration, and direction. Who called stays private.
With your permission, Callvent reads time, duration, direction and available numbers from the Android call log. Matching contacts are assigned.
Get notified
When the call is detected, a notification with the call duration appears after you hang up. Tap it or choose “Quick Save”.
Assign a contact
Contact detected
Pick the contact from your address book – one tap. Apple intentionally prevents apps from reading phone numbers from calls. That’s why you assign the contact yourself.
Callvent automatically reads the phone number from your call log and matches it to your contacts. You can adjust the contact if needed.
Save
Check the contact and time, add an optional note or tag, then save to your chosen calendar. You can find the entry there later.
Everything you need. Nothing you don’t.
Call Detection
On iPhone, Callvent detects calls through Apple’s CallKit while the app is active. These can include cellular calls, FaceTime and CallKit-compatible calls in WhatsApp, Teams or Zoom. CallKit does not provide phone numbers for these calls. Log missing calls using a widget, the Action Button or Siri.
With your permission, Callvent reads the Android call log and matches available numbers to your contacts. WhatsApp, Teams and other VoIP calls are captured only if they appear in that log.
Assign Contact in One Tap
Automatic Contact Matching
Assign the call to a contact – one tap on the name is all it takes. You decide what data gets saved.
Callvent reads the phone number from your call log and automatically matches it to your contacts. Adjust the match if needed.
