The pause button is too small on an IPhone to easily tap the first time during a difficult workout with my fat, clumsy fingers. ### 4/5 — Almost 5 stars *2011-09-14, version 4.0.1* Great app. Easy to use. An integrated tap counter would be nice. It would be nice to keep track of reps too. Maybe design it to count negative and positive counts and multiple reps scalable from 1 to ? The ability to save programs would be a huge plus. Thanks for the app. Use it all the time. ### 2/5 — Too plain and simple! *2010-11-14* Dissapointing purchase... doesn't allow you to easily set up your own interval sessions and features are limited. ### 3/5 — Great interval timer, but missing key feature *2010-10-12, version 0* I've been using this app for sometime. It is an excellent interval timer, easy to configure. However, it only allows you to have one interval timer configured at once. It has become tiresome having to change the timer settings each time I want to run a different interval workout. If I could create and save multiple timers, this would be a 5-star app and probably the best interval timer available, considering the combination of features and ease of use. ### 4/5 — Program Saver *2010-10-04, version 0* Would love to see an update that would allow you to save workouts so you don't have to reprogram it every time you want to do something different. Otherwise, great app! ### 2/5 — Great app, but... *2010-08-15, version 0* UPDATE: since the last update the iPod volumes fluctuate. It was really good when I first bought and they just keep improving it. Keep it up! Also, people complaining about the icon are ridiculous. Have you ever seen a real interval timer? ### 3/5 — It works *2010-08-14, version 0* Good at timing but could definitely use improvement. The app needs to be updated for iOS 4, the icon is a joke, need to be able to program and save more than one timer, app just majorly needs cosmetic improvement. ### 4/5 — (v4) Good ap *2010-07-15, version 0* Does what it says. A big thanks to the developers for quickly fixing the bug that paused the timer when locking phone. ### 2/5 — I loved this app until I upgraded to 4.0! *2010-06-29, version 0* I had been training to do a walk/run marathon with this app and it was absolutely one of the best training tools I had! And of course as the saying goes, "Don't try anything new the day of the marathon." Well, I had upgraded to the iPhone 4 and I didn't think anything of it. But when I started my race, the sounds wouldn't work and would only vibrate (which of course I couldn't feel because it was in my running pouch) because I put the phone to sleep so that the screen would be locked. And I couldn't keep the screen on, because everytime I moved it would pause. I finally gave up on the application after playing with it for 6 miles in my race. I was really diasppointed because I couldn't even use it the way I had trained! So please upgrade this because I really liked this app! ### 3/5 — Sound Issues *2010-06-26, version 0* I love this app but since updating my phone to 4.0, I can't hear the samples of the sounds like I used to when selecting a sound, and when the phone goes to "sleep" the sounds don't work, just the vibrate. The phone has to stay "awake" for the sounds to work during a workout. Please fix these issues on this otherwise great app. Thank you! ### 4/5 — Great app but fix 4.0 issues!! *2010-06-26, version 0* Fix the new issues. Once updated to OS 4.0 issues have come about. Interval sounds are not working properly. ### 4/5 — Interval Timer by Scott Fritzinger *2010-05-16* This app is simple and works well as an interval workout timer. For me it is a little short on instructions and at first I thought I had wasted my money but I persevered and now I use it every day. ### 4/5 — Nearly there *2010-04-13* My most painful app, given the tough circuit sessions it gives me! Only gripe is to make the pause button less sensitive as i keep knocking it mid session. ### 5/5 — An interval training must! *2010-04-01, version 0* In the last few years I have really focused on interval training. There were two main problems, finding a timer that could handle different interval types without resetting, and hearing the buzzer over your music. This app handles both of these things beautifully. All you need to do is start your favorite playlist going on your iphone, and then start the interval timer. You have the option of the program stopping the song when the buzzer goes off, so you are assured of hearing it. It then starts the song again in the same place. You can set low and high intensity intervals within a larger interval as well. This is a must for anyone who wants to design and use interval training into their routines. GREAT APP GREAT PRICE! ## Most critical reviews (10 lowest-rated) ### 1/5 — Useless update *2014-10-20* I've had this interval timer for a long time & it's been brilliant(5 stars)...until this week. It was updated overnight and not for the better. Each time I open a preset interval sequence, it 'logs out' and returns to my home page,at least for the first 3 attempts....really unhelpful. ### 1/5 — was good till update *2011-10-18* was good until last update now keeps crashing. Sounds dissapear halfway through workout. Timers reset to for no reason to standard settings!! What happened? ### 1/5 — Requirements are WRONG!!!! *2010-05-25* I bought this for my touch and it is not compatible! Even though the site says it's compatible with touch, it needs the iphone....there have been a couple of apps that i have downlaoded and have not worked. Apple need to go through their apps and state if things are actually compatible with touch and which need a higher iphone. I don't like wasting money and probably will not try very many apps until that happens. ### 1/5 — Nope *2010-03-27* Does not work at all, uninstalled, reinstalled, does not work. ### 1/5 — Cannot get this app to work *2010-02-14* Until there is some instructions on how to use this I'm giving it 1 star. I've wasted loads of training sessions trying to get this to work. I put the set time to 3min but this seams to set the high interval time to 3m whatever I have actually set it to. I never get a low interval. Only high and rest. This app is far too complicated fir something that should be really simple. Surely all that is required is low time, high time, and total time. ### 1/5 — Quit working after 7/6/09 upgrade *2009-07-07, version 0* Worked fine on the morning of 7/6/09, got an upgrade. On the morning of 7/7/09, it looks all different and the app closes every time I hit the start button, so it's now useless. I loved it before. Help! It used to be great for Tabatas. Set the rest time to zero and use the low interval for the 10 second rest. If it ever works again. If it doesn't come back soon, I guess I'll have to find another timer. It's a shame. I really liked the way it worked before. ### 1/5 — Timer review *2009-03-09* This would be a perfect interval timer if only you could leave It and return to continue where you left off, each time you leave you have to start over at the beginning. It is very nice to be able to play your iPod while the timer is running but you can't leave the app to change your song because you will have to start the timer from the beginning. ### 1/5 — Not worth it *2009-02-26* This device has no flexibility - it wouldn't let me choose 0 and it only allows for 1 interval. Spend the extra $1 and get the next version up. ### 1/5 — Am I missing something? *2008-08-16, version 0* I originally left the review below. This application worked one time for me. Now it crashes every time. I really want to like this app, but it needs work. Original review: I loved using this on the treadmill this morning. There's 2 thing that prevented me from giving 5 stars. 1. There's isn't a pause button. 2. There's only a stop button. When you press it, the app doesn't just stop, it exits and takes me back to iPhone's home screen. This was kind of annoying. I liked the tones. Great little app for those doing interval training. ### 2/5 — Has problems *2011-10-18* The sound of the app is way too loud. If I'm using my headphones, it can really hurt and you can't adjust that volume. When previewing sounds it screws with entire phones sound level. Loading lists is buggy and it doesn't delete them. It can function but needs to more QA. ## Most praised reviews (10 highest-rated) ### 5/5 — Good stuff *2021-02-09* I use this all of the time and especially in combination with a music app. It does everything that I need it to without any fuss. Good, reliable no nonsense timer. Xx ### 5/5 — Silly users *2014-06-11, version 5.3* I've had this app since it was created and I've never had an issue with it. Always opens and runs flawlessly. I wish it could set up different timers between "sets" but that's just being anal. Get the app and enjoy. ### 5/5 — Running intervals & tabata awesome *2013-08-21* I was in need of a functional app to set separate intervals to train for running intervals and this is perfect. I love that you can save workouts with a name so I can have stairs, running & tabata all saved and ready. The best app - I tried two others that just did not have the flexibility as this one. I love that I can say do 10 reps of the set doing which has been planned out by my trainer. ### 5/5 — After all the research... *2012-06-20, version 5.3* Yes indeed! I finally found the interval timer app that is the best, and it works under fire! Wether your Ipod is off or you're on another app, the timer still runs in the background like real time. It took me awhile to figure out low and high intervals, but I so get it now. Your high interval could be your actual work out while your low interval could be your resting time. I like to think of the low interval as moving on to the next weight work out apparatus. And I figured out that rest means end of the number of sets. Or you can make rest your interval if you set the high or low interval to zero! I'm rambling on because this is truly a great app that I tested. I should be ok at the gym tomorrow and onward. ### 5/5 — Invaluable *2012-06-09* Excellent gym companion. Use pretty much all the time with my cardio ### 5/5 — Street jitsu association *2012-01-07* What a fantastic App this is ! Easy and simple to use ideal for our kickboxing club for timing rounds. And because it's on my iPhone it's portable and I can use it anywhere. Most definately recommended. ### 5/5 — Customer feedback *2011-06-15* Bought this timer a month ago, has been really good app- very simple to use just as an work/rest timer but with lots of options to make the intervals more complex. Good clear display. Can play music while using the timer aswell, started using it as a boxing timer but now use it for a load of other stuff aswell ### 5/5 — INTERVAL TIMER *2011-02-16* Awesome, this interval timer works perfect and has no problems at all, works A+++++++, wont freeze or stop half way thru your workout you can trust it.....some of the others i have tried were more expensive and hopeless but this one is well worth the $1.19..... This interval trainer is by far my favorite fitness app!!!! 5 starts all the way!!! GOOD JOB : ) ### 5/5 — New version for iOS4 is even better *2010-07-10* My iPhone automatically locks itself due to a security policy of my Exchange email server so I require an app that works in the background when the phone is locked. This update does just that and works exactly as expected. Thanks very much for the update. ### 5/5 — Great App! *2010-04-12, version 0* This app helped me start running again. I love it! It does just what it is supposed to do and is easy to use. Plus you can still listen to your music while it is counting down. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
