ChatClock – Local Time for WhatsApp Web

Automatically see a contact's estimated local time in the WhatsApp Web chat list.

ChatClock helps you choose a better time to message international contacts by showing their estimated local time directly in the WhatsApp Web chat list. When a chat is displayed as an international phone number, ChatClock uses the country calling code to estimate a default time zone. You can correct any estimate with a manual time-zone override. Main features: - Shows an estimated local time beside supported WhatsApp Web chats - Detects a default country and time zone from international phone numbers - Displays work, morning/evening, and night status at a glance - Supports both 12-hour and 24-hour time formats - Handles daylight-saving time automatically - Lets you set a manual IANA time zone for any contact - Allows contact overrides to be exported, imported, or deleted - Stores contact names, phone numbers, time-zone overrides, and display preferences locally in Chrome - Includes a 24-hour full-feature trial Plans: - Monthly: USD $3.00 per month - Lifetime access: USD $9.99 one-time Checkout, taxes, invoices, and subscription billing are handled by Creem as the merchant of record. Payment-card details are entered on Creem's hosted checkout and are never received or stored by ChatClock. Privacy: ChatClock reads only the visible chat names and phone numbers needed to provide its local-time feature. Phone-number parsing and time-zone estimation happen locally. It does not collect or transmit message text, images, files, WhatsApp credentials, cookies, or browsing history. Contact names, phone numbers, and time-zone overrides are not sent to the billing service. Important: A country calling code indicates where a phone number is registered; it does not reveal a contact's current physical location. Countries with multiple time zones use a default estimate until you select a manual override.
