- Reviews - "I've been using the Round Timer app on my iPhone for about as long as I've had my Iphone... If you're someone that's training for rounds, doing circuit work, etc. this app is worth your 99 cents. With the level of customization you get, the app is competitive with the way more expensive round timer devices that can cost upwards of $10-100." - by Shawn Lord, www.mastersdivision.com "I found a GREAT interval timer app in the iTunes store for 99 cents!!! It's called Round Timer and it works like a dream!!!" - by Miss Lee, forums on thecathenation.com "Its a really useful applications. Beats carrying around that big round timer from the old days." - by Michael Manna, T4Show.com ----------------------------------- - Description - The Round Timer was the first round/sparring/boxing timer available in the AppStore and, as a result, the most refined and stable. Don't be fooled by knock-offs (other developers copying our interface and layout). The Round Timer is a convenient round/boxing/sparring timer for your iPhone/iPod touch, now compatible with iOS 8. The Round Timer is a fully functional round/sparring timer that allows you to customize the length of the rounds, warning bell and resting period. Each of these intervals can be configured separately up to an hour. It will run in the background even if you switch to another App. With the sound themes, you can choose which alarm sounds to use: boxing/MMA, a relaxing Zen theme, and a few others. Don't like any of the dozens of preinstalled sounds? Don't worry! You can record your own sounds. For large, loud environments you can plug your device into a stereo, or for small sessions put it in the corner of the mat. The Round Timer is great for any sparring or interval training: boxing, MMA, grappling / bjj, martial arts, yoga, meditation, crossfit, exercise, workout, stretching, etc. Working out to music is not a problem. Start your music playing in the iPod app, then start RoundTimer. The sounds will play over top of your music without interrupting it. Please feel free to e-mail support@plainandsimplesoftware.com to suggest new sound themes! Interested in interval training (Tabata, symmetrical, etc... intervals)? Check out our "IntervalTimer". Want more control? Check out "UltraTimer". Want full programmability and randomized intervals? Look at "UltraTrainer".

Verdict

The call

The clearest difference is price: Boxing Interval Timer at Free against Round Timer's $0.99. Boxing Interval Timer also leads on rating (4.8 vs 3.8) and ratings volume (13K vs 21). Round Timer's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Boxing Interval Timer holds the better App Store score, 4.8 against 3.8. That said, the two scores are not equally well evidenced: Boxing Interval Timer has 13K ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 74% of Round Timer's written reviews are positive against 59% of Boxing Interval Timer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Round Timer ships an update every 3 weeks, Boxing Interval Timer every 3 months. The most recent releases landed on October 13, 2026 and October 12, 2026 respectively.
