Focus on Your Workout, Not Your Timer. Meet the interval timer app designed for simplicity without subscriptions, built for HIIT, Tabata, circuit training, and everything in between. Why this app? Yes, there are countless timers on the App Store. But when I couldn’t find one that just worked without endless subscriptions or bloated features, I built my own. This app strips away the fluff and delivers exactly what you need: a reliable, customizable countdown timer that repeats cycles automatically. No ads, no "pro" upsells, no excuses. Key Features: Custom Workouts: Build routines with intervals, rest periods, and rounds tailored to HIIT, Tabata, or circuit training. Training Cycles: Set up repeatable sequences (e.g., 30s work / 10s rest x 8 rounds), then let the timer do the work. Flexible Countdown: Start with prebuilt templates or create your own from scratch. One-Time Purchase: Pay once. Own it forever. No subscriptions—because a timer shouldn’t bill you monthly. Why isn’t this free? A free browser-based version exists at timekit.uk/workout-timer if you want to try the basics. This app is for those who value a polished, ad-free experience and want to support a solo developer aiming to make a living creating genuinely useful tools. Simple. Effective. No Bull. Download now and spend less time fussing with timers—and more time crushing your workouts.
