Best Interval Training Timers (HIIT, Tabata, EMOM & More)

A good interval training timer isn't complicated — it just has to work when you're upside-down in a burpee and can't tap the screen. Half the apps on the store fail this basic bar. Here's what an interval timer actually needs, and how to run HIIT, Tabata, EMOM, and boxing rounds without fighting your phone.
What an interval timer must do
Configurable work/rest in seconds. Not minutes. Tabata is 20/10. A timer that snaps to full minutes is useless.
Round counter. You should never have to remember which round you're on. Big display, obvious number.
Loud, distinct sounds for start vs stop. A single beep for both is a great way to accidentally rest during the work interval.
Screen-on lock. If your phone dims mid-workout you've lost the timer. A good browser interval timer keeps the tab awake.
No signup. Nobody is signing up for an app between warm-up and workout.
The main interval protocols and how to time them
Tabata: 20 seconds work / 10 seconds rest × 8 rounds = 4 minutes total. Brutal if done at true max intensity. Full protocol in our Tabata training guide.
Classic HIIT: 30–60 seconds work / equal or double rest × 6–12 rounds. Flexible; program it however your session calls for.
EMOM (Every Minute On the Minute): A prescribed number of reps at the top of each minute; whatever's left of the minute is your rest. Set a repeating 60-second timer.
Boxing rounds: 3 minutes work / 1 minute rest × 3–12 rounds. Amateur is 2/1. Look for a timer with a warning bell at the last 10 seconds of the round.
Running intervals: 400m repeats, hill sprints, or 30/30s. A simple work/rest interval timer beats a running watch you have to fiddle with.
Why a browser interval timer beats an app
Fitness apps want your email, your goals, and your credit card before they let you set 20/10. A browser-based interval timer loads in one second, works on any phone, plays sound out loud, and doesn't sell your workout data. For 95% of home training, that's all you need.
Common mistakes
Silencing the phone (now you're relying on the visual, which you can't see mid-plank). Setting rest longer than work on true HIIT (defeats the point). Skipping the warm-up round. And running Tabata for 20 minutes — it's four minutes for a reason.
Frequently Asked Questions
What's the best interval timer for HIIT at home?+
Any free browser timer that lets you set work/rest in seconds, counts rounds, and plays loud sound. You do not need a paid app for HIIT.
Can I use a regular countdown timer for Tabata?+
You can, but you'll be resetting it every 20 or 10 seconds. A proper interval timer runs the whole 8-round protocol on autopilot.
Do I need Bluetooth speakers?+
Only if your phone speaker isn't loud enough to hear over music. Any timer that goes loud enough is fine.
What's the difference between HIIT and Tabata?+
Tabata is a specific HIIT protocol: 20/10 × 8 rounds at true max intensity. HIIT is the general category — any pattern of hard-work intervals with short rest.
