Cons
Con Avoid, not userfriendly
Merges multiple accounts into one timeline and there is no way to get around that. This is ridiculous. only recommended if you have one account. Seeing one timeline is impossible. The app appears to be a copycat of Plume minus the ads in many ways. The app is missing the translate feature. The Trends feature doesn't work. Interactions missing features too. It's not intuitive as well, rather complicated. So very few downloads.
Con Hasn't been maintained and it's buggy
Can't view your or anyone's LISTs, Conversation view is very frustrating to use if you can, no Likes visible of tweets. Only positive easy switching of multiple accounts (more than 3). Not maintained.
