Please update for IOS 11. ### 3/5 — Simple, but not great *2017-02-06* 3 stars because it does what it says it will do, as long as you're willing to hold your phone while you're running. If you want music, or to have your phone in your pocket or pack, you're out of luck. Can't hear the sounds very well and can't change them to something better. I don't know what the paid version is like, but I don't think it's worth it because there are other free apps that work better. ### 2/5 — Disappointed *2016-09-05* There is nothing intuitive about this app. Unable to set up a run/walk interval and have it repeat that cycle X amount if times. Instead, you have to set up each run and each walk as many times as you'd like to repeat them. For a paid app, extremely disappointed! ### 2/5 — Worked great at first *2016-06-22* This app was wonderful the first two weeks I used it. Now this week, the intervals aren't working. It tells me to "walk" and then "run" but then never prompts me to walk again. I am really hoping that with an update it will begin working correctly again. I liked the simplicity of the app and how I could listen to my playlists while running. ### 1/5 — Bad app *2016-03-24* This is the worst app I've downloaded, I asked for my money back but I only received a short rude response back from them, will never buy an app from them again and I hope it was worth the $2 ### 1/5 — Disappoint *2016-01-12* Extremely frustrating. Had to start over three times because it won't work in the background. Finally just gave up and used my watch. Looking for another option. ### 5/5 — Use it all the time *2015-12-26* Simple and useful! ### 1/5 — Won't run in background *2015-11-20* Can't get it to run in the background with my Nike app open. As soon as I open another app it stops working. So, basically useless. ### 3/5 — T.s *2014-10-13* I love this app however when playing music the voice no longer comes through ....this feature use to work perfectly !!!!! Please help ### 5/5 — LOVE this app! *2014-08-09* I needed an app to streamline my marathon training, and this app is just what I was looking for. It is easy to adjust, keeps me on pace, and works well with iTunes playing my music. ## Frequently asked questions about rTimer Lite ### What is rTimer Lite? rTimer Lite is an interval training application designed for iPhone and iPod Touch.
