Timber: Custom Interval Timer

Timber is a customizable interval timer and routine builder. Whether you're crushing a HIIT workout, sinking into a deep focus session, or perfecting your morning schedule, Timber lets you build your routine, your way.

Build once, reuse anywhere. Create simple countdowns or advanced multi-step routines with reusable blocks, groups, repeats, nested timers, media cues, and background playback.

Stop switching between separate apps for HIIT, Tabata, Pomodoro, meditation, stretching, coaching and cooking etc. Timber lets you build the exact routine you need.

🎬 Guide Every Step with Rich Media Cues
Don't just watch the clock. Attach rich media to any timer step so you know exactly what to do and when to do it:
• Add YouTube, Vimeo, and Dailymotion video demos
• Attach local video, audio, image, recording, and text prompts
• Use text-to-speech voice cues for hands-free guidance
• Add music, countdown sounds, and instructions to individual timer steps
• Keep cues running with native background playback

🧱 Build Once, Reuse Anywhere
Create simple or highly advanced timers using our flexible block-based architecture.
• Create reusable timer blocks
• Group blocks into circuits, sets, and rounds
• Repeat blocks, groups, or full timers

• Edit linked blocks once to update them everywhere, or unlink for a custom version
• Duplicate timers and blocks for easy modification
