WJD Exclusives review for Notify! Back in Stock|PreOrder

1 / 5

Jan. 16, 2026

This app charges $500+/month for one job: send notifications. And it can’t even recognize a valid U.S. phone number if it has dashes or +1. I entered ***-***-**** and +* ***-***-**** (both valid), and the app told me my phone number was “not valid” with zero guidance. If you only accept 10 digits, say “Use **********.” Don’t gaslight users with a generic error. For a paid product at this price, basic input validation and clear error messages are the bare minimum. Right now it’s expensive friction.
