You can’t get rid of them! They take over the screen and timer and there’s no way to continue the workout without closing out the app and starting over. It’s ridiculous and happens CONSTANTLY and I’ve had this app for years!! Don’t waste your money! ### 1/5 — Why are there ads after I pay? *2018-03-12* App worked great for a while and now ads are popping up in the middle of my workouts. I press done and they don’t go away no matter how many times I press Done. I tried to go to the support page, but I got page not found. Thinking they went out of business. ### 1/5 — Really!?! Paid to remove ads and still have them *2018-02-21* Ok!! I paid 2.99 to get rid of ads so they won’t pop up in the middle of my circuits can someone explain to me why I still have ads popping up in the middle of my workouts causing to have to stop and start over if you can not fix this problem refund me my 2.99 or whatever else you can do because since I spent my 2.99 plus tax when Apple charges me i’ going to keep the freaking app I want this fixed!!!!!!!!!!!!!!!!! ### 3/5 — Almost what I need... *2018-02-14* It was easy to set up and customize, but it didn’t let my music play while it was going, and it didn’t have any sounds to switch activities. I need a timer I don’t have to watch like a hawk. ### 5/5 — Love it! *2017-03-10* This is an awesome interval timer and just what I've been looking for! The only things I would change is allow for customized rest periods, instead of a base 5 seconds, and allow to copy exercises in routines. ### 1/5 — Lost data *2017-02-01* I went to work out this morning and all of my workouts I had painstakingly set up were gone. ### 5/5 — Intuitive app *2015-01-11* Just what I was looking for! ## Frequently asked questions about Intervals ### What is Intervals?
