Quick comparison table

1. Home Workout Timer & Tracker

Best for: most people who want a clean, no-account circuit timer on iPhone.

Home Workout Timer & Tracker wins because it gets out of your way. You can set work, rest, rounds, cycles, and prep time from one screen without digging through menus. It runs reliably in the background while music or podcasts play, so you can focus on the workout.

• Templates for Tabata, HIIT, strength, bodyweight, and core.
• Custom sessions with exercises, meters, reps, or seconds.
• Clear timing and round tracking without social features.

Most people won’t need separate Tabata or HIIT apps after this. Get Home Workout Timer & Tracker or Home Workout Timer & Tracker on the App Store.

2. Seconds Pro Interval Timer

Best for: iOS users who want color-coded timers and voice prompts for HIIT and Tabata.

Seconds Pro is known for detailed interval customization. You can build complex HIIT, Tabata, and circuit structures with different colors for work and rest. Text-to-speech announcements call out intervals, which is handy when your phone is across the room. Templates help with repeat sessions, but casual users may find the extra options more than they need. It’s iOS only.

3. Interval Timer - HIIT Workouts

Best for: Android users who want a free, no-frills interval timer.

This one keeps work, rest, and prep setup simple. It runs in the background while you use other apps, and full-screen alerts are easy to read mid-set. It’s built for HIIT and circuit workouts, not advanced multi-phase programming. If you want a straightforward timer with no accounts or clutter, it’s a solid free pick.

4. Tabata Timer: Interval Timer

Best for: Android users who want a dedicated Tabata and circuit timer.

Set your sets, work time, and rest time straight from a clean screen. Sound and vibration alerts keep you on pace without glancing at the phone. The round counter is big enough to read during sets, so you always know where you are. If your training is mostly classic 20/10 or similar work/rest splits, this app handles it without extra setup.

5. Exercise Timer

Best for: iOS users who want exercise-specific routines and workout history.

Exercise Timer lets you name exercises inside circuit and HIIT routines instead of just setting generic intervals. Multi-phase customization supports different training blocks in one session. Workout history helps you repeat or review past work. It suits trainers or detailed planners who want structure and records. The trade-off is a bit more setup time than simpler timers.

6. SmartWOD Timer

Best for: CrossFit and functional fitness athletes on Android.

SmartWOD Timer covers AMRAP, EMOM, For Time, and Tabata modes. The minimalist display is easy to read from across the gym. It’s built specifically for WOD-style sessions instead of general interval use. If you follow functional fitness programming, the specialized modes fit better than a basic timer.

7. Gymboss Interval Timer

Best for: iOS users who liked the physical Gymboss timers.

This is the digital counterpart to the popular hardware timer. It offers programmable interval tracking with audio and vibration alarms. You can save multiple routines, which helps if you rotate between HIIT, strength, and cardio circuits. Longtime Gymboss users will feel at home, but new users may find the interface a little dated.

8. Impetus Interval Timer

Best for: Android users who need complex, asymmetrical circuit setups.

Impetus handles advanced interval customization, including uneven work/rest structures that many timers can’t do. Preset templates for different sports help you start quickly, but the learning curve is higher for casual users. It’s best if you already know your exact intervals and want detailed control. For simple Tabata or HIIT, it might be overkill.

9. Timer Plus - Workouts Timer

Best for: iOS users who want rounds and cycles clearly displayed over music.

Timer Plus shows the number and duration of rounds and cycles, so you can see the whole workout structure at a glance. Built-in flash and sound alerts help when your music is loud or your phone is face-down. It works with background audio, which makes it an easy everyday option for timed circuits.

How we picked these apps

We judged each app on interval customization, background reliability, alert types, platform availability, and ease of use. We tested iOS and Android options where we could. Home Workout Timer & Tracker won for simplicity, speed, and lack of clutter. We skipped apps with intrusive ads or bloated features. We considered both free and paid apps but did not require an account.

Frequently asked questions

What is a circuit timer?

A circuit timer cycles through timed work and rest periods for circuit training, HIIT, or Tabata. Sound, vibration, or visual alerts tell you when to switch exercises, so you don’t have to watch the clock. It replaces a stopwatch and manual round counting.

Can I use circuit timers with my own music?

Most circuit timer apps run in the background while music or podcasts play. Timer Plus and Home Workout Timer & Tracker are designed to sit alongside background audio. Test your specific music app, because iOS and Android handle audio ducking differently.

Which circuit timer is best for beginners?

Home Workout Timer & Tracker is the simplest option. It has a short setup path, clear start/stop controls, and no unnecessary features or account requirement. You can start with a template or build a basic work/rest circuit in seconds.

Home Workout Timer & Tracker is the best circuit timer for most training. It covers work/rest rounds, cycles, and prep time without forcing extra apps or account setup on you. Download it if you want a timer that stays out of your way. Get Home Workout Timer & Tracker.
