About this app

Interval Timer: HIIT Workout helps you time workouts, training rounds, and exercise sessions with a simple setup built for movement. Whether you are planning HIIT, Tabata, cross training, boxing drills, running sets, yoga flows, or breathing exercises, Interval Timer: HIIT Workout gives you a flexible way to organise work and rest intervals without slowing you down.

Use the app to create sessions that match the way you train. Build a routine from scratch, edit an existing setup, or start from a ready preset when you want to move quickly. Interval Timer: HIIT Workout is designed for people who want a reliable workout timer with a clear display, progress feedback, and easy controls that make every interval easier to follow.

🔥 Set up workouts your way
Create training sessions around your exact routine. You can edit and save workout setups so your common patterns are ready when you need them. This makes Interval Timer: HIIT Workout a practical tool for interval training, conditioning drills, and focused practice blocks, helping you stay organised from warm-up to final round.

⏱️ Build intervals with presets or custom timing
Choose from ready presets or create custom intervals for your own pace. Set work periods, rest periods, round counts, and session flow to suit the style of training you prefer. The app makes it easy to adjust the timing for a short burst session, a longer circuit, or a calm breathing routine.

📅 Track progress across sessions
Keep an eye on your training history with progress tracking and calendar-based review. This makes it easier to follow your routine over time, compare sessions, and stay consistent with your goals. Review how often you train and how your routine is building week by week.

🔔 Stay on beat with sound, vibration and voice
Stay focused while the timer does the counting for you. Sound alerts, vibration, and voice guidance help you notice each change in interval without checking the screen constantly. That means you can keep moving through workouts, sports drills, and exercise sets with fewer interruptions.

🎨 Train with a clear full-screen display
Follow each interval on a color-coded full-screen display that keeps the current phase easy to see at a glance. This helps you stay oriented during fast workouts, intense rounds, and high-energy sessions. The app is built to make timing feel simple, even when your routine gets demanding.

• Save the sessions you use most so your favourite workout formats are ready when training starts.
• Switch between ready presets and custom timing to match HIIT, Tabata, cross training, or focused practice.
• Review progress in a calendar view to keep your training rhythm visible and easier to maintain.
• Use sound, vibration, and voice cues so you can stay engaged with exercise instead of watching the clock.
• Share results after a session when you want to show what you completed or keep a record for later.

Interval Timer: HIIT Workout is a practical choice for people who want timing support for active routines, from intense intervals to steady conditioning. It brings workout setup, progress tracking, and easy session control into one place so your training stays structured and your focus stays on the effort.

A good interval timer without unnecessary complications that fits my needs! Anything more than the basic single-pattern alternation is behind a premium paywall, but I love that the free version still gives you plenty enough functionality. In terms of accessibility, I appreciate the large buttons (makes it easy to press when I'm flopping around after a workout). The "close ad" buttons are awkwardly placed and require precision to click, but I get it. A simple app that does what it needs to.

does what it should do perfectly, including voice which is really helpful when you are exercising. For the rest not very complex, wish it was just part of my standard android timer app but oh well. also one-time purchase would be fair rather than a subscription model..

Excellent app. Does exactly what it's supposed to with no fuss. I especially like the countdown at the end of sets and the widget on my lockscreen as I frequently use it for running intervals and makes it super simple to keep track of where I'm up to.
