Best 7 Interval Timers in 2026: Top Picks for Every Workout

Home Workout Timer & Tracker is our pick for a reliable, no-fuss interval timer. It structures work and rest periods without getting in your way. Here are seven interval timer apps we tested, each suited to different training styles, devices, and budgets.

Quick comparison

1. Home Workout Timer & Tracker

Best for: Anyone who wants to build a workout once, hit start, and focus entirely on moving.

We think the best interval timer is one you don’t have to fuss over. Home Workout Timer & Tracker gives you full control: you set work and rest periods, number of sets and rounds, and optionally add exercise names, distance targets, or rep counts. Build a session from scratch or choose a template from the Tabata, HIIT, strength, or core packs. Then save it and reuse it with a single tap.

• You can set up anything from simple 20/10 Tabatas to complex EMOM chippers with rotating movements.
• Audio and vibration cues let you keep your phone face-down or locked, so you never need to glance at it mid-set.
• A location-tracked running segment option displays live distance during outdoor intervals.
• The built-in workout log quietly tracks every session so you can see progress without spreadsheets or extra apps.
• An iOS home-screen widget pins your most-used timers for instant access.

The interface stays clean and readable, even during your toughest sets. Other apps bury you in menus, but this one stays out of your way. It works just as well for a beginner setting up a basic 30/15 circuit as it does for a coach programming a multi-round chipper with different exercise durations.

2. Seconds Interval Timer

Best for: People who want guided interval sessions without designing everything from scratch.

Seconds includes a library of prebuilt templates for HIIT, Tabata, and circuits. Pick a plan and go. The text-to-speech feature announces exercise names during intervals, so you never stop to remember what’s next. Audio alerts work in the background even with the screen off or while using other apps, and you can leave your phone safely tucked away.

3. GymNext Flex Timer

Best for: Lifters who train near a GymNext LED clock or want heart-rate-driven intervals.

GymNext Flex Timer was originally built to work with GymNext’s wall-mounted LED clocks, but it works great as a standalone interval timer. It ducks your music volume during beeps and voice cues so you hear every countdown clearly. If you train with a heart rate monitor, you can pair it via Bluetooth and get alerts based on specific zones. That makes it a solid pick for conditioning workouts where you want physiological guardrails.

4. SmartWOD Timer

Best for: CrossFitters and functional-fitness athletes running AMRAPs, EMOMs, or For Time workouts.

SmartWOD Timer gives you exactly what you need in a busy gym: huge high-contrast digits, a round counter you can’t miss, and one-tap mode switching. It handles AMRAP, EMOM, For Time, and Tabata without any decorative clutter, so it’s fast to reconfigure between classes. Coaches and solo athletes alike appreciate the no-nonsense layout that reads clearly from across the floor during high-intensity flailing.

5. Intervals Pro

Best for: Runners and Apple Watch users who want interval targets beyond simple time.

Intervals Pro takes full advantage of the Apple ecosystem. Each interval can target a specific distance, time, or heart rate zone from Apple Watch. Completed sessions sync with Apple Health, closing your rings and logging data automatically. The Watch app gives haptic taps instead of beeps, which is nicer in a shared gym. The clean interface keeps your focus on pace, not buttons.

6. Chronocat

Best for: Budget-minded users who want a genuinely free interval timer with no ads or account setup.

Chronocat works as both a workout interval timer and a Pomodoro focus tool. Neither function feels tacked on. You can load a template, tweak it quickly, and start a session without hitting a paywall. The free version gives you the full feature set, not a limited trial, which makes it a standout for students, remote workers, and anyone who doesn’t want to subscribe for timed beeps.

7. Tabata Timer: Interval Timer

Best for: Android users who only ever need classic Tabata work/rest blocks.

Tabata Timer does one thing: you set your work seconds, rest seconds, and number of rounds, then hit start. It skips feature bloat, so you go from opening the app to your first interval in just a few taps. The big countdown fills the screen, easy to read even when you’re gasping through the last rounds.

How we picked these apps

We installed each interval timer on iPhone or Android and ran timed sessions across several workout styles, including HIIT, Tabata, EMOMs, strength circuits, and outdoor intervals. We judged setup speed, how deeply you can customize intervals, reliability of audio and vibration alerts, and whether the display remains glanceable during hard effort. Apps that forced mandatory accounts, served intrusive full-screen ads between rounds, or demanded too many taps to start a simple timer got the axe. The final list covers different platforms and specializations, from complex functional-fitness programming to bare-bones Tabata. No developer paid for inclusion, and the top spot reflects our honest hands-on preference.

Frequently asked questions

What’s the difference between an interval timer and a stopwatch?

A stopwatch just counts up; you have to watch the clock to know when to switch. An interval timer automatically flips between work and rest with audio or vibration alerts, so you can focus on your movement instead.

Can I use interval timers for running or cycling?

Yes. If you want pace-based road intervals, look for apps with distance or heart rate targets. Intervals Pro is great for runners who use Apple Watch for distance goals, and Seconds works well for simple time-based repeats on the road or trail.

Do these apps work with the screen locked?

Every app we recommend supports background audio or vibration alerts with the screen locked. In most cases, your music continues playing and the interval cues simply speak over it without interrupting playback.

Which interval timer is best for beginners?

Home Workout Timer & Tracker is a stress-free way to start: build a simple work/rest cycle once in Custom mode, save it, and you’re all set. If you want a free option to try interval training, Chronocat is a solid pick.

The verdict

Home Workout Timer & Tracker earns the top spot because it’s both reliable set-and-forget and flexible enough to handle any interval structure you can dream up. It works as well for a first-time HIIT explorer as for a coach programming multi-round EMOMs. If you want an interval timer that gets out of your way and lets you focus on the work, grab it here.
