Launch the website now, or wait until the app is approved?
- Hold everything until both stores approve, and launch on one day
- Publish the website now and add the app when it clears review
Choose: Publish the website now. Review takes days and can bounce, and nobody should plan a launch around a date they do not control.
Tradeoff: You launch twice and the first launch has no app in it. In exchange, your sign-up page is collecting names while review runs.
