>Ramsay Brown and his garage start-up Dopamine Labs made a habit-breaking app as well. It’s called “Space” and it creates a 12-second delay -- what Brown calls a “moment of Zen” before any social media app launches. In January, he tried to convince Apple to sell it in their App Store.
Somehow I don't think that was why his app was rejected.
60 Minutes has been played by the creator of the app.
Facebook's Groups app uses (disclaimer: as far as I can tell) an interesting technique involving saving data URIs to the home screen and then deep linking them.
OTOH the easiest way to do this would be to have the Space app help to automate creation of Safari shortcuts on the home screen (which would be called Twitter and show the correct icon), which launches a hypothetical page in Safari like https://twitter.space.usedopamine.com which would show the pulsing animation for 12 seconds, before launching the actual Twitter.app.
