Interval training is one of the best methods to enhance your physical fitness and burn calories and is therefore a basic part of many physical exercise and workout sessions. It is broadly defined as repetitions of high-speed/intensity work followed by periods of rest or low activity. This application helps to manage and control the intervals. Just define the duration of the work and relax periods and the number of cycles you want to do. You can choose whether you want audio feedback by alert or sound. So you can listen to your music without monitoring the screen. Despite enhancing your health this application can be used to structure any kind of repetitive work. ## Key features - Customizable work and rest intervals - Adjustable number of cycles - Audio feedback options (alert/sound) - Background music compatibility - Versatile for various repetitive tasks ## Recent user reviews (10 of 10) All indexed reviews: https://appshunter.io/ios/app/workout/id288240647/reviews.md ### 3/5 — Reset screen frozen *2012-06-30* I used this app fIrst time. It was good but at the end of my set time, the reset box would not work and screen frozen. I tried to reset by powering off iPad. ### 2/5 — Not great *2012-05-03, version 1.1.2* Text so small that it cant be seen at any distance. there is only one work and rest interval that can repeated over and over rather than programming a series of intervals as would be the obvious and not too much more difficult thing to do. Not worth the small amount of money spent. ### 3/5 — Good Timer *2011-09-10, version 1.1.2* The only thing I'd change is having a 5-10 second lead time before the timer actually starts. Would make it easier to press the start button and be ready to go. ### 5/5 — Great *2011-07-11* Easy to use, stops me losing count when doing my interval training, does exactly what it says on the tin. ### 1/5 — Do NOT Buy this App!!!! *2011-07-10, version 1.1.2* It is not worth the $1.99 I paid for it. I took a chance and it was NOT worth it. There are far better FREE interval timers out there! Horrible on the iPad. Timer is far too small; no savable routines etc etc etc. ### 1/5 — Doesn't work :( *2011-02-03, version 1.1.1* The whole point of this app is to alert you when the interval changes but the gong never sounded. I was so excited when I saw this app, simple, clean I thought it would be just what I needed to do Sun Run training. I downloaded it, set the intervals and headed out for session. The first high intensity interval seemed to last forever. When I finally checked the time I realized that I blown passed the interval and most of the rest period that followed. I tried turning it up. I tried turning off my music. Eventually I stood there and stared at the countdown and watched the interval click over in total silence. The vibration mode works, but I'm training outdoors in winter and can't feel the vibration in the pocket of a winter coat. ### 2/5 — Pb *2010-09-25* Problème pour se remettre en start ### 4/5 — Simple et efficace *2010-07-21* Appli simple et efficace qui permet de faire du fractionné tout en écoutant sa musique... ### 4/5 — Great Little App *2009-08-12, version 0* This app does the job. The only thing you need to be aware of is that you need to turn off Auto-Lock on the phone (Settings > General > Auto-Lock), as when the phone goes to sleep, so does the app :-), and the input fields are rather small for those with poor eyesight. Support is good, as there was an issue with the previous version, which has been fixed. ### 1/5 — Not worth it *2009-01-03* Don't do it not worth the $1.00 very lame ## Frequently asked questions about Workout ### What is the price of Workout?
