Frequently Asked Questions
How long are professional boxing rounds?
Professional boxing rounds are 3 minutes long with 1 minute of rest between rounds. Championship fights go up to 12 rounds, which is why the default preset on this timer is set to exactly that: 12 rounds, 3 minutes, 1 minute rest. Amateur boxing uses 3-minute rounds for men and 2-minute rounds for women.
How long are MMA rounds?
MMA rounds in the UFC and most major promotions are 5 minutes long with 1 minute rest. Non-championship fights are 3 rounds; title fights are 5 rounds. This free MMA timer includes a preset configured to those exact settings.
Is this boxing timer really free?
Yes, completely free. No account, no email, no credit card. The timer runs entirely in your browser with no server calls during your workout. You can even save this page to your phone's home screen for offline use.
How do I use a boxing round timer?
Select your sport preset or customize your rounds, round time, and rest time. Hit Start. The timer will count through your warmup, then alternate between rounds and rest periods with a bell sound at each transition. A warning signal plays near the end of each round so you can finish your combination strong.
Can I use this as a heavy bag timer?
Absolutely. It is one of the best free heavy bag timers online. Set your round time (2 or 3 minutes is standard), add a 30-second or 1-minute rest, and set the number of rounds you want. The bell will keep you honest so you can stay focused on the bag instead of watching a clock.
What is the best free boxing timer for mobile?
This one. It is designed mobile-first, works on iPhone and Android without installing anything, and the full-screen display stays on during your workout. Tap the screen to pause mid-round. For the best mobile experience with extra features, check out the Shadow Boxing App on iOS.
Does it work for Muay Thai?
Yes. The Muay Thai preset sets 5 rounds of 3 minutes with 2 minutes rest, matching standard stadium rules. You can also customize it for gym sparring, clinch work, or conditioning rounds at any length you prefer.
Can I use this timer for shadow boxing?
Shadow boxing is actually the main use case this timer was built for. Short rounds with tight rest periods keep intensity high. Try 3-minute rounds with 30 seconds rest, or go with 12 quick rounds of 2 minutes to build endurance. The warmup countdown gives you time to get loose before the first bell.
What is the warning bell for?
The warning signal plays a set number of seconds before the end of a round (10, 15, 30 seconds, or more, your choice). In a real boxing gym, the trainer calls "ten seconds" so the fighter knows to finish their combination. This timer does the same automatically.
What Fighters Are Saying
"I've tried every free boxing timer I could find. This is the only one that actually sounds like a real bell and doesn't have ads covering the screen mid-round. Use it every morning for shadow boxing."
"Set it up on an old iPad I have mounted in my home gym. Works perfectly. I use the Muay Thai preset, loud bell setting, and it cuts right through music. Exactly what I needed and it cost me nothing."
"Coach at our boxing club was spending money on a gym timer app. I showed him this. We switched instantly. The pro boxing preset with 12 rounds is perfect for our sparring sessions."
"As someone who trains MMA at home, I needed something I could pull up fast on my phone. This is on my home screen now. Tap, start, train. The round dots at the top are a nice touch."
