Spotlight: Flud is one of the best Android torrent clients out there4
|Developer: Delphi Software||Download: Android|
|Category: Tools||Price: Free (with ad support) / $2 (ad-free)|
That aside, Flud offers pretty much everything you'd expect from a competent torrent client, including the ability to select which files to download, set file/folder priorities, magnet link support, encryption, IP filtering, proxies, protocol support (NAT-PMP, DHT, UPnP, µTP, PeX), moving files while downloading, and other convenient functionality. Android KitKat (Android 4.4) users must note that the operating system won't let apps write to the external SD card. This is not a bug in the app, and you can still download files in the folder 'Android/data/com.delphicoder.flud/' on your external SD card. But note that that folder is deleted when Flud is uninstalled.
Being an up to date Android app, Flud has a clean Material interface, an optimized UI for tablet users, and comes with Light and Dark themes. It's being actively developed, with new features in the pipeline coming as soon as they have been cooked up. The app is free to use, but is ad-supported. So if you like how it works and don't want to be pestered by banners, you can buy the ad-free version for around $2 (link). Happy leeching/seeding!
