- Reviews - "UltraTimer by Plain and Simple Software is an ideal tool if you want to use your iPhone or iPod touch to keep you on track... UltraTimer is a simple but valuable tool for anyone who requires a flexible, hands-free event timer." - by Kyle Bailey, Macworld.com "Ultratimer: a must-have for interval training. ... Of the timers that I've tested, UltraTimer is my favorite. Its combination of ease-of-use and functionality make it the benchmark fitness timer app." - by Sang Tang, tuaw.com "So I purchased the UltraTimer app from the AppStore on my iPhone. It was the only purchased app I have that was worth it!" - by Casey, rawandfit.com "...the other thing that I have come to love is my Ultratimer application on my iPod... the Ultratimer is a step beyond." - by Jennifer, oncearoundvenus.blogspot.com "UltraTimer iPhone App Is EXACTLY What I’ve Been Looking For. ... I was worried that it might be difficult to use, but I found it incredibly easy and I was running with a program that only took me about five minutes to program, and that included recording the voice prompts." - by Laura Moncur, starling-fitness.com ----------------------------------- - Description - UltraTimer is the original fully-programmable and customizable interval timer in the AppStore. As a result, it is the most refined and feature-rich interval timer today! UltraTimer is an easy and convenient way of timing any activity or series of activities. You can set a single timer or multiple timers, each including series of count-down intervals that run back-to-back. Each interval can be customized to play a different alarm sound from the included library, as well as change the background color for visual feedback. It is easy to set up intervals for any activity: training (martial arts, boxing, mma, circuit training, interval training, Crossfit, HIIT / HIT, yoga, meditation, exercise, workout, cycling, running, etc), time management for switching between multiple projects, or anything else you can think of. For a complete workout, you can set up a Timer Group which will play individual timers back to back. Start out with your favorite Warm Up timer, then run through your favorite Training timer, and end with a Stretching timer. UltraTrainer will run you through your full workout automatically. The included sound library comes with a wide variety of reminder sounds suitable for relaxing timers, high intensity activities, and everything in between. Custom sounds can also be recorded via the microphone; you are not limited to the included sound library. Exclusive to our products, users can browse the Timer Exchange, a community where people freely exchange timers. Search, browse, and download timers that other users have uploaded. If you want, you can upload your own timers to share with others. If a friend also owns UltraTimer, you can exchange timers via e-mail or the clipboard to use other methods. Using UltraTimer with music playing is not a problem. You can begin playing music on the timer screen, pause it, or skip to the next track. Just a few features in UltraTimer: - Timer Exchange community - Runs in the background - Copy/Paste Intervals and Actions - Delayed start time - Over 70 included sounds - Record your own sounds - Large countdown timer display - iPod music playback control lets you pause/play the current track or move to the next track from the countdown timer screen - Pause the timer to temporarily halt the activity - Timer state is saved if it is interrupted - Still runs if screen is locked - Intuitive setup If you're looking for an App that coaches you as you train, check out "UltraTrainer."

Verdict

The call

The clearest difference is price: Exerp Staff at Free against UltraTimer's $1.99. Exerp Staff also leads on ratings volume (1.3K vs 12) and rating (4.4 vs 4.2). UltraTimer's advantage is review sentiment (57% vs 19%) and iOS requirement (8.0 vs 15.0). On update cadence, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Exerp Staff holds the better App Store score, 4.4 against 4.2. That said, the two scores are not equally well evidenced: Exerp Staff has 1.3K ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 57% of UltraTimer's written reviews are positive against 19% of Exerp Staff's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

UltraTimer ships an update monthly, Exerp Staff every 2 weeks. The most recent releases landed on October 26, 2026 and October 25, 2026 respectively.
