Your call log is read inside your browser. Caller numbers never leave this page, and nothing is uploaded.

Your call log already records every missed call. This page lays them out by the hour.

Plumbers, HVAC and roofing outfits, auto repair shops, local stores, property managers and the agencies that run their call ads all export the same kind of file. Drop it in and read the pattern at a glance.

01

Weekday by hour

Every cell shows its missed rate and its counts, for example 50% and 1 of 2. Hours with no counted calls show a dash, not 0%.

02

Your business hours

Set your opening time, closing time and days. Calls split into business hours and after hours, worked out to the second.

03

Repeat callers

Numbers with two or more missed calls and no answered call in the file, matched on their last 10 digits whatever the formatting.

04

By source

Missed rate for each tracking source and tracking number, when your export carries those columns. Four CSV downloads carry the same figures.

Built by Mulkern AI Systems. Counts and rates from your own call log, nothing more.

Works with CSV exports from CallRail and RingCentral, Google Voice Takeout call files, or any call-log CSV. Not affiliated with CallRail, RingCentral or Google.

Google Voice Takeout call files (unzipped): unzip the Takeout file first, then drop the Calls folder or its files in. Only the file names are read.
