Bematist matches the موسیقی it plays to شما running cadence. It reads شما steps per minute from گوشی شما's motion sensors و picks tracks whose tempo fits the pace you're actually running, switching automatically as شما pace changes. Half- و double-tempo tracks count as a match too, so a 172 BPM track suits an 86 SPM pace و vice versa. Every track is analysed برای tempo on-device, directly from the صوتی files in شما library, so matching works entirely offline once شما library is scanned — بدون حساب کاربری, no network, no server. Triage mode lets you rate tracks while you run — skip, keep or like, by an on-screen gesture or an earbud button — و sorts them into playlists afterward. Every run is logged با its cadence و track-matching detail, browsable afterward in session history. Bematist collects nothing و has no servers. It plays موسیقی from files already on دستگاه شما. رایگان و متن‌باز, GPLv3 licensed.
