Ratings and reviews

Great App, the only minor issue is with logging in. When you want to log in with your Google account it redirects you to a browser that you have to sign in and go through all the 2 step verification process.

Not very helpful, as it is now. To use it, after 100 references screened, you have to pay, even though you have been invited to a review by a registered user. The app could be improved, e.g., one screen per paper would be helpful, filter and sorting methods being kept constant when you re-access a review.

Filtering doesn't work. Tried to filter by year while screening, but it shows 0 results, no matter which year I choose even though there are at least 1000 papers in each category. It has to be an app issue because the filtering function works fine on the webpage itself.
