Wavalid
Validate WhatsApp numbers in real-time, before you send
What it does
Wavalid checks whether a phone number is on WhatsApp in under 100ms, across 195+ countries. Pull it into your stack through a REST API, MCP server, dashboard, or Chrome extension. Cold outreach teams and SaaS onboarding flows use it to stop messaging dead numbers. Pricing is credit-based, with no subscription lock-in. Each call cleans your list a little more, so bounce rates and messaging costs drop too.
Check whether a phone number is registered on WhatsApp before you send to it. Real-time API, bulk CSV validation, and a Chrome extension. 195+ countries.
wavalid checks any phone number against WhatsApp in real time (sub-100ms), so developers, marketers, and ecommerce teams stop sending to numbers that don't exist. Sub-100ms per number, so you catch invalid numbers before they hurt your bounce rate, not after. Every check is saved to your batch, so you never pay to validate the same number twice. Never sold. Every list collected over time picks up numbers that were never on WhatsApp, were reassigned, or were mistyped. Validate the whole list in one pass and keep only the ones that work. Sending to a number that isn't on WhatsApp wastes a send, hurts your delivery rate, and can flag your account. Check the list first, message only the numbers…from wavalid.com

I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up.
