People that do a clean install shouldn't post which apps are working for them on this forum. That's not the way iOS is used by the vast majority of people.
I don't agree with that statement or yours, but I'm just pointing out that it goes both ways.
A vast majority of iOS users don't install beta software on their phones... the ones that do, should take every possible step to make sure it'll work correctly before complaining about it. Additionally, it's good policy in general to completely wipe your phone and start over every once in a while to keep it working optimally. I would do that even if I wasn't installing beta versions.
I installed iOS8 yesterday and so far the ONLY problem I'm having is that Google Sheets doesn't work correctly. Other than that, everything works great with a restore/set up as new install of the beta on a 5S.
