I had an iPHone for a few months and noticed my reddit time dropped considerably. Part of it was because iPhone (or Reddit? I don't even know who is to blame here) wouldn't let me choose the reddit app I wanted as the default. If a friend sent a reddit link to me it'd try and open in Safari and I'd get annoyed and just ignore it.

I'm back on Android now where I can choose default apps and now if a friend sends a link, I click it and read it, then I click over to the homepage, then 20 minutes goes by as I mindlessly scroll. It's a blessing and a curse to be able to use your phone the way you want to, I guess.
