This site doesn't instill a great deal of trust in me handing over google credentials. Some more information about who you are, where you're located etc would probably be beneficial.
I'm not affiliated with either product, but FlatGA uses OAuth so you're not "handing over Google credentials." The app requires explicit permissions to: (1) view your configuration information, (2) view your reports, (3) view your Google email address. You could revoke access at any time.
Happy to answer any questions you have.
Idea: You could make this an embeddable widget (for a 12-24 USD yearly fee), ideal for CMSs like Joomla, WordPress etc. Basically an iframe with some settings page in the CMS (dead simple on both WordPress and Joomla) to store the login.
If I click on the small download (?) symbol, I get a js error. Its in the 'Top pages & Referrals (Top 15)' panel.
+1, I'd also be keen on it as an angular/react/etc plugin
Do GA users find it worrying that Firefox and edge beta are blocking GA by default now?
