Sound familiar?
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.
The app automatically detects when a call ends and instantly reminds you to create a calendar entry. Pick a contact, add a quick note, done.
Four steps. Ten seconds.
From phone call to calendar entry – without typing a single name.
Call detected
Answered, made, or missed – Callvent detects every call in the background. It captures time, duration, and direction. Who called stays private.
Get notified
Right after you hang up, a notification shows the call duration. Tap it or choose “Quick Save”.
Assign a contact
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.
Save
Add an optional note, pick a tag, and tap save. Done – the entry goes straight to your calendar.
Everything you need. Nothing you don’t.
Automatic Call Detection
Callvent detects every call automatically – cellular, WhatsApp, FaceTime, Teams, Zoom, and more. It captures time, duration, and direction. No app on iOS can read phone numbers from calls.
Assign Contact in One Tap
Assign the call to a contact – one tap on the name is all it takes. You decide what data gets saved.
Calendar Entry in Seconds
Title, date, time and duration are pre-filled. Just add an optional note and save.
Quick Save
Swipe in the call list or tap the notification – and the entry goes straight to your default calendar.
