Intervals Pro grows up: a 14-day trial, a real price, and a coach in WhatsApp
The experiment worked. Intervals Pro is retiring the perpetual free tier and settling into a proper shape: a 14-day trial, then Pro at £19.99 a month. Everyone already subscribed keeps the price they signed up on. And the coach now lives where you already do, in WhatsApp, with notifications you can install to your home screen.
