OmniTimer

Whether you train hard, study smart, or just need a reliable timer that stays out of your way, OmniTimer gives you total control over every second.
Features
Unlimited Timer Engine
Forget basic start-stop timers. Design complete interval sequences — warm-up, work, rest, cool-down — then group them into sets, add repeats, and let the app handle the rest.
Build Any Sequence
Chain unlimited intervals into sets, chain sets together, and repeat everything. Skip rules let you drop the first rest or alternate automatically.
Focus Mode & Controls
Focus mode hides distractions and lock mode prevents accidental taps. The screen stays on so you always see the countdown.
Always Running
Minimize the app, lock your phone, switch to your music — the timer keeps going. Control everything from the notification.
Preset Marketplace
Not sure where to start? Browse a curated library of ready-made timers organized by category — HIIT, Tabata, Yoga, Pomodoro, Stretching, Breathing, and more. Preview every detail, then add to your collection in one tap.
AI Preset Generator
Describe your workout in plain English and let AI build the timer for you. "HIIT 30s work 10s rest x8 with a 3-minute warm-up" — the app generates a complete preset with intervals, sets, and repeats. Runs on-device or using your preferred cloud AI.
Training Programs
Follow structured multi-week programs with day-by-day tracking. Couch to 5K, Tabata Challenge, HIIT Starter, Fartlek, Pyramid Intervals, and more — each with pre-built daily sessions, automatic progress tracking, and completion rewards.
Sessions & Statistics
