BUILD ANY TIMER YOU CAN IMAGINE

Design complete interval sequences — warm-up, work, rest, cool-down — grouped into sets with repeats. Skip rules let you drop the first rest or alternate intervals automatically. Give every interval its own name, color, icon, and image.

🏋️ PRESET MARKETPLACE
Browse 30+ ready-made presets by category — HIIT, Tabata, Yoga, Pomodoro, Stretching, Breathing, and more. Add any preset in one tap.

🤖 AI PRESET GENERATOR
Describe your workout in plain English and let AI build the timer instantly. "30s work, 10s rest × 8 rounds" generates a complete HIIT preset in seconds. Runs on-device with GGUF models (fully offline) or connect OpenAI, Gemini, or Ollama with your own API key.

📅 TRAINING PROGRAMS
Multi-week programs with automatic day-by-day progression. Couch to 5K, Bridge to 10K, Tabata Challenge, HIIT Starter, Fartlek, Pyramid Intervals, Sprint Intervals, and Tempo Builder — each with pre-built daily sessions and completion rewards.

🔊 SOUNDS & VOICE COUNTDOWN
Choose a different sound for every interval. Voice countdown calls out "3… 2… 1…" so you never need to glance at the screen. Adjustable volume up to 2×, vibration alerts, loop or single play.

📊 PROGRESS TRACKING
Every session recorded automatically. Total sessions, focus time, streaks, hourly and weekly charts, per-preset history. Export to CSV for deeper analysis (Pro).

⏱️ KEEPS RUNNING — ALWAYS
Minimize the app or lock your screen — OmniTimer keeps ticking in the background. Skip or pause from the notification shade. Focus mode blocks accidental taps mid-session.

🎨 MAKE IT YOURS
Light and dark themes with dynamic Material You colors. 8 font families, high contrast mode, reduced motion support. Organize presets with custom tags and icons.

🔒 PRIVACY FIRST
No account, no cloud sync. Your data stays on your device. Crash reports collected automatically for stability — usage analytics are opt-in.
