Stremio and popcorn time. It's netflix for torrent. No popups or animation. I think there is one banner somewhere, but it's so discrete I don't even remember.

uTorrent has a search tab for example.

Not sure how you consume yours but I do the same old search on pirate Bay + download with Deluge.

Deluge is a good torrent app, the frogs boiled slowly with uTorrent and BitTorrent as they were overcome, but deluge still appears to be ad free!
