Callvent
Turn every phone call into a calendar entry
I built Callvent because every work call vanished the moment I hung up. Now a call ends, you get a notification, and one tap saves it to the calendar you already use, with contact, note, tag, and callback reminder. Works with regular calls plus WhatsApp, FaceTime, Telegram, Signal, Teams, and Zoom, and writes to iCloud, Google Calendar, Exchange, or CalDAV. Everything stays on your device: no account, no cloud, no tracking. Native for iPhone, Android, Apple Watch, and Wear OS.
Callvent started with a problem I kept having. I'm on the phone all day, and ten minutes after a call I couldn't remember when I talked to someone, for how long, or what we agreed on. I tried notes apps and a CRM. Both were too much work, so I quit after a week every time.
So I built the thing I actually wanted. A call ends, you get a notification with the duration, you tap once, and it lands in the calendar you already use. About ten seconds. You can add notes, a tag, and a callback reminder if you want, but you don't have to. It works with normal calls plus WhatsApp, FaceTime, Signal, and Teams, and writes to iCloud, Google Calendar, Exchange, whatever you have. Everything stays on your device. No account, no cloud.
It's free to try for 7 days. After that it's a cheap subscription, or a one-time Lifetime if you hate subscriptions as much as I do.
I'd really like to hear what you think, especially what's missing. Thanks for taking a look. - Robert, mittl medien
