Death by Burpees Timer

A minimalist Android timer with premium audio feedback for interval training

Death by Burpees Timer is a minimalist Android application designed for interval training workouts. The app provides precise audio feedback without requiring you to look at your phone, making it perfect for exercises like burpees, HIIT, EMOM, or any minute-based workout routine.

✨ Features 🎯 Two Training Modes 1. Routine Mode (Modo Rutina) Customizable work and rest intervals Support for seconds or minutes in each phase Configurable number of sets (1-99) Visual phase indicator (ENTRENA! / DESCANSO) Set counter showing current progress Pausing mid-work is safe: the phase resumes exactly where it stopped 2. Death by Burpees Mode Timer sounds every minute with a 10-second warning Burpee counter showing how many burpees to do each round Progressive color animation from cyan to red as time runs out Configurable duration (1-999 minutes) Minimalist skull icon interface ⚡ Quick Presets Three built-in routines (Tabata, EMOM 10, AMRAP 20) available in one tap Saving your own configuration as a named preset for repeat sessions A preset opens straight into its timer screen with the values pre-filled 📜 Session History Every completed session is logged with its mode and duration Running total and current consecutive-day streak Keeps the last 100 sessions 🔊 Audio System All sounds are synthesized in real-time using AudioTrack — no audio assets ship with the app. Every buffer is generated once at startup and served from a cache, so nothing is recomputed while the timer runs.

Sound Description Prepare ticks 5-second pre-start countdown: ascending 500→800 Hz ticks with vibration, ending on a double-tone "GO!" Warning 10 escalating beeps before each phase or minute ends (rising frequency and volume) Work/Minute Long tone (~900 ms) with harmonics, like a race start whistle Rest Soft descending three-tone sequence End Clear four-note resolution Note: tones are routed through USAGE_ALARM and the app requests and abandons Android audio focus around playback, so they cut through other audio. Haptic feedback pairs with every cue (short buzz, or a pattern for the final one).
