SMS opt-in (in-app)

Public proof for Twilio / A2P 10DLC reviewers

Pre-launch — SMS only to finish sign-in

Daily HIIT has not launched on the App Store yet. It is an iOS app. Consumers do not enter a phone number on this website. There is no keyword text-in, QR code, paper form, or verbal sign-up.

Today, members authenticate with an email one-time code. We are adding SMS one-time passcodes so they can complete authentication by text instead of email. Text codes are faster to receive on a phone, easier to auto-fill, and more people finish sign-in. SMS is only used for those login codes after in-app opt-in. We do not send marketing or promotional texts.

This page is a hosted mock of that in-app screen (including the unchecked consent checkbox) so reviewers can verify the call-to-action without an App Store listing or a private login.

Message flow

1 The consumer opens the Daily HIIT iOS app.
2 They type their own US mobile number on the sign-in screen.
3 They see an unchecked checkbox and the SMS disclosure (privacy and terms URLs, message and data rates, STOP / HELP).
4 They check the box, then tap Send code. Send code stays disabled until the box is checked. That check + tap is the affirmative opt-in.
5 Daily HIIT then sends one 6-digit authentication SMS to that number only. No SMS is sent before opt-in.
6 They enter the code to sign in. Reply STOP to opt out; HELP for help.

In-app screen (hosted mock)

The consent checkbox below is unchecked by default, matching the live iOS UI. This mock does not collect numbers or send SMS.
