HIIT Timer is a focused, professional interval training tool designed for fitness enthusiasts, coaches, and anyone who values efficient, structured workouts. We build around real training scenarios with multiple workout modes, bilateral training, drag‑and‑drop sorting, and personalized plans—so you can stay consistent and make measurable progress.

Our product principles are simple and reliable: smooth performance on devices, practical guidance in content, and respect for privacy. We continuously refine accessibility, responsiveness, and usability for both mobile and desktop, so the timer feels natural wherever you train.

We’re a small team with product, engineering, and athletic backgrounds. We ship openly and iterate quickly, aiming to provide clear training paths and positive feedback loops for users of all levels. Have ideas or suggestions? We’d love to hear from you and build a better training companion together.
