This is the Hadith companion to Greentech Apps Foundation's Quran application, and it carries the same terms: free, no advertising, no paid tier, published by a non-profit.
The library covers the major collections — Sahih al-Bukhari, Sahih Muslim, Sunan Abu Dawud, Jami at-Tirmidhi, Sunan an-Nasa'i, Sunan Ibn Majah and others — with Arabic text alongside translations in several languages.
Narrations are organised by book and chapter the way the printed collections are, so a reader who knows where something sits in Bukhari can navigate to it directly rather than relying on search. Search is there as well, across text and translation.
It works fully offline once the collections are downloaded, which for a reference of this size is the practical difference between something you can use and something that needs a connection every time.
Free on Android, with no advertising.
