Late last year, the American site Buzzfeed learned that Twitter had been working for over a year on a messaging app for its social network, much like Facebook with its Messenger app but ultimately Twitter had buried the app. Starting from the observation that a messaging app specific to the DM on Twitter would be interesting, an independent developer Andrew Hart worked on such an app and just launched it on the App Store, it is TwIM . This app offers users a simple way to instant messaging to manage private messages for a Twitter account. It is possible to search for a Twitter user by name or user name, and to discuss with even if it has not installed TwIM. The app can display and send tweets, photos, videos, gifs, emojis, maps with the user's location, as well as web pages. It is also possible from the app to block a Twitter user who sends spam or for some other reason. From the settings of the app, a user can switch to another Twitter account , but also allow his Twitter account to receive messages from anyone and not just the other accounts he follows. The app supports a lot of recent iOS features like the ability to send a DM message on Twitter using Siri , interactive notifications, or 3D Touch . In short, a well designed and practical iPhone app for users who send and / or receive quite a lot of DM on Twitter. In addition, the app is free and does not include any in-app purchases .
