Needs to be updated layout not functioning on my iPhone 6+ I’ve used this timer for a fairly long time now. I really appreciate its flexibility and the variety of times included. It wasn’t formatting well and hadn’t been updated for a while. I am grateful that it is back in play. Thanks! I works great again. ### 2/5 — Crashes *2016-12-20* This version crashes frequently. The ability to import and export timers seems to have gone away. Trying to access the timer exchange results in an instant crash. ### 4/5 — Stopped working *2016-04-13* i've used and loved this for years, this week it stopped working, when I tap selected workout nothing happens. Is this due to new Ios? Will there be an update to fix. ### 3/5 — Sound issues *2015-10-20* Since the ios 9 update, i have problems with the sound. When i use a single interval, the ending sound is not playing. I checked the sound level of my phone and it's ok. Please check this bug !!! ### 2/5 — Bug fixes created another bug *2015-09-11, version 7.1* Crashing is fixed but now I cannot name or rename any of my timers or groups. When I click on them I see the naming dialogue box briefly then it becomes a white outline box. Please fix is so it can work again. ### 1/5 — Used to be good....... *2015-05-27, version 7.0* This app was, I repeat, was the best timer app out there, now unless you are running iOS 8 or newer (iPhone 5 and up) its absolutely useless and the developers haven't done anything as you can see from the reviews. It will just crash over and over and over....... ### 4/5 — Not the app it was *2015-04-02, version 7.0* The retro digital digits ruin the apps class. Either take it back to the older digit display or give the user an option for the visual display. Other reviews posted are factual concerning the apps downgraded new features. A class app has been demeaned with inferior upgrades. Not a wise choice on the designers part. Sometimes you have to learn to leave well enough alone at the visual level and just refine the underlying code. ### 2/5 — Crashes on category select *2015-02-08* I have been a long time ultratimer user and have found this to be the best interval timer for my needs. I haven't used the app in a quite a few months and recently got back into fitness only to find the app crashes on selection of any category on Ios 7/ iPhone 4. This is a show stopper. P&S Software please fix. ### 2/5 — Lost perfection with update *2015-01-30, version 7.0* I used to love this app. The update robbed me of perfection. The title of my set gave me my sequence order. Now instead of my title, when the timer chimes it just says "new interval". Duh. The chime tells me that. You took away my cheat sheet when you took away my titles. Why? ### 1/5 — Constant crashing. *2015-01-01, version 7.0* Tap copy =crash. Tap paste=crash. This app used to work just fine, now it’s unusable. Moving on. ### 1/5 — please fix the bugs *2014-12-30, version 7.0* I'm a trainer and group fitness instructor and in the past has been great! since the update it's been crashing...and can't share timers anymore because it crashes HOPEFULLY THEY WILL FIX THE BUGS SOON ### 1/5 — Version 7 is a disaster *2014-12-23, version 7.0* Tap copy, it crashes. Tap paste, it crashes. Tap add, it crashes. Tap delete, it crashes. See a pattern here? I've been using this app for a long time. This update makes me want to find an alternative. ### 1/5 — Ultra timer *2014-12-18, version 7.0* Malísima actualización ### 1/5 — Buggy *2014-12-14, version 7.0* Please, folks, fix this app. The current update is very buggy and should not be out there. I use a 4s running IOS 8 and had no troubles with the app until this update. Also, if you can add an easy to access screen lock, I would love that feature. For now, the app is really unreliable. Examples: there is no way to exit the help section; the app started a timer when opened; sometimes buttons work, sometimes they don't. ### 1/5 — This update is horrible so far. *2014-12-09, version 7.0* I installed this app on my old iPod touch 4 running the latest IOS 6 to see if it worked with voiceover. It just crashes when I try to run it, I’m taken back to the screen I was on. I don’t want to update it on the device I use it on that is running IOS 8.1.2 because I’m not sure it will work there either and I don’t want to be without the program for an extended period of time. I’m getting a third device I’ll install it there and see about updating this review. Ill also update it if they come out with another update that works. ### 1/5 — CRASHING!! *2014-12-09* Since updating it crashes on opening. Only have iOS 6.1.6. Not impressed as I use it regularly. ## Most critical reviews (10 lowest-rated) ### 1/5 — Needs update *2022-03-03* This app doesn’t display properly on my iPhone 13 mini. ### 1/5 — Unable to set time *2017-09-22* It was a great product until the latest update. Cannot use at the moment ### 1/5 — 7.3 Broken *2016-04-25, version 7.3* I cannot modify interval times since last update. When you save the time it replaces it with 521263:42:28 as the time no matter what I set. Before this, it was a great app. Please fix ### 1/5 — Unusable *2016-04-22* Since the latest update. Simply doesn't work. You can't create intervals properly. You may select 1 min and it decides you selected 35 mins. Every time you select any interval it changes the time you selected rendering the whole app pointless. Don't waste your time downloading it. Very disappointed as it was great. ### 1/5 — After update 7.3 not able set or change time intervals. *2016-04-21, version 7.3* The app is useless now. No times can be set or updated. ### 1/5 — Voice Prompts? Can't open on IPod touch *2016-01-29* Purchased and no instructions on how to do voice prompts. No warnings for start or end of intervals. Downloaded to iPod touch and when opened it shuts down. iPod has latest IOS 6.1. Will give more stars if issues fixed. ### 1/5 — Useless! *2015-10-22* No end timer sound on ANY timer - don't waste your time with this app! ### 1/5 — used to love ultratimer *2015-10-02, version 7.1* About a week ago the start button disappeard from my app! I can see all of my timers but I cannot use any of them. Without support and no start button, this app is useless. ### 1/5 — Even worse than before... *2015-09-16, version 7.1* Doesn't crash now but you can't rename any existing interval nor name a new interval. All you get is a non-responsive white dialogue box. Basically, the app is non-functional. ### 1/5 — App Crashes Constantly *2015-06-08, version 7.0* The app is virtually useless. Every attempt to alter a timer results in a crash. Every attempt to delete, copy, paste, etc causes a crash. Awful. Moving on to something else. Will not use "plain and simple software" app developers in the future. Terrible. ## Most praised reviews (10 highest-rated) ### 5/5 — Still the best workout timer *2022-01-16* UltraTimer is still usable even on my iPhone13ProMax. The old timers I created don’t expand to the new screen size but the new timers I create fill the screen. I will it would be upgraded, but as long as it works, I am still happy with it. By the way, you can even make very complex timers for cooking. ### 5/5 — Best fitness app *2021-03-30* Been using this app for years, does exactly what you need it to, perfect for customizing any workout ### 5/5 — I figured it out. Good app *2019-12-29* I did figure it out and works quite well for what I needed. It took a a minute for me to get it but I like it now. ### 5/5 — Best workout partner ever!! *2017-09-29* I love this app so much. I just plug in my headphones and hit the gym. My trainer gave me exercises on this when I first started with him, but now I add my own. Please don’t ever stop updating this!!! I’d be lost without this! ### 5/5 — Great Running App *2013-07-20* This is a great app for interval running. ### 5/5 — Great *2012-08-24* One of the greatest apps that ive got. I use it or everything ### 5/5 — Needs update fix.....and they did it! *2012-05-13, version 5.5.1* It's fixed and back to a fantastic app, thanks for checking the reviews and following up developers ......issue that's fixed was.......Was a great app. Can't create a group timer with new update. Wait till they fix it......It's fixed as of May 12 ### 5/5 — Exactly what I needed *2012-04-26, version 5.3* An interval timer app that lets you record your own prompts and then you can transfer between iOS devices to avoid reentry of data. Superb. ### 5/5 — Excellent CrossFit Timer *2012-03-27, version 5.3* Great app! Works well on both iPhone and iPad. Might want HD version for iPad. 100% satisfied. Only timer I could find that would easily let me set up Tabata Something Else and other multi interval workouts. ### 5/5 — Exactly what I needed *2011-11-05* I was looking for an app to help me with interval training while I do some rehab work and this is absolutely perfect. No more trying to count in my head or tripping while I look at my watch. This app is so simple to use and has all the configuration I need --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
