## What is BUSHIDO?

Round timer for boxing, BJJ, Muay Thai and MMA — with taiko war drums built in.
Interval timer for Tabata, HIIT, boxing rounds and strength sets — plus a 25/5 focus timer — scored with original Japanese-style music built right in.
No ads. No subscription. Works offline.

BUSHIDO Timer counts your rounds with taiko, bell and gong, and plays original war-drum and phonk tracks made for training. Prefer your own playlist? Keep Spotify or Apple Music playing — BUSHIDO only adds the cues on top.

FIVE WAYS TO TRAIN
• 疾 TABATA — 20 sec all-out, 10 sec rest, 8 rounds
• 烈 HIIT — 40 sec work, 20 sec rest, 10 rounds
• 闘 ROUNDS — 3-minute rounds with 1 minute between, for boxing, Muay Thai, kickboxing, MMA and sparring. For BJJ rolls, set it to 5-minute rounds
• 鍛 SETS — no clock on the lift: tap when your set is done, then a 60-sec rest, 5 sets
• 禅 ZEN — 25 min focus, 5 min break, 4 rounds, with calm deep-focus music for work or study
Change the seconds, rounds and get-ready time of each one. Each workout remembers its own settings, and you can reset to the defaults any time.

MUSIC THAT FIGHTS WITH YOU
• 40 original tracks free: 32 war-drum & phonk tracks for training, 8 deep-focus tracks for ZEN
• BUILT-IN plays our tracks. MY MUSIC keeps your Spotify or Apple Music playing and lays the cues on top. OFF gives you cues only
• Taiko starts the round, the bell calls rest, beeps count the last 3 seconds, the gong ends it
• Music dips for a moment on each cue so you always hear it — adjust cue and music volume separately

CUES YOU CAN'T MISS
• Keeps counting with the screen locked
• Live Activity on the lock screen and in the Dynamic Island shows the round and the countdown
• Big controls that are easy to hit with sweaty hands: START, PAUSE, SKIP, RESET

APPLE WATCH
• Runs on its own on your wrist
• Haptics: a strong double tap for GO, a soft tap for rest, clicks in the last 3 seconds
• Heart rate on screen, keeps running with your wrist down, saves each session as a workout in Apple Health
• Uses the numbers you set on your iPhone and keeps its own streak

RECORD & STREAK
• Calendar marks each day with the kanji of what you trained
• Day streak, sessions and minutes at a glance
• Home Screen widgets: streak and today (small), this week plus one-tap TABATA / HIIT / ROUNDS (medium)
