Arrow Launcher's latest update is all about bug fixes and wallpapers

The developers also kicked off a beta program a long time ago, which offer participants a taste of what's to come. Although the beta version of Arrow Launcher is not for everyone, at least it's a good indication of what developers try to bring to a larger audience.
Another new change included in the update is the addition of a Bing wallpaper icon on the home page. Arrow Launcher users can now tap on that icon in order to change it, if that's what they wish.
That's about all you get in the latest update for Arrow Launcher, so if you've been using the app, it's definitely worth upgrading to version 2.9.1. Hopefully, there will be less issues and the launcher will be much faster than before.
