Mika, you were right, and we have fixed it.
Our page carried $29/mo wording left over from our waitlist period, while checkout showed the intro price followed by the standard renewal. That mismatch was ours, not a misreading on your part, and the page has been updated today.
For anyone reading this: HeyCatch starts at $18.95 for a 2-week intro period, with 4-week and 8-week plans at $28.95 and $48.95 for the first period. After the intro, plans renew at the standard price shown at checkout, and you can cancel anytime before renewal. Every price, the renewal terms and how to cancel are shown before you pay.
Vlada has already replied to you directly. If you still want to try it, the intro price stands.
