Add Customizable Routine Color Changes

I really like this app. There’s quite a bit about that I like. I use this app for doing the PT exercises I’ve been given from my physical therapist. One of the features I like is that it gives you the month showing the days you’ve done any of your routines. Great feature to show my therapist when and which pt I’ve done. I love the color tones. I like that I can play my music right in the app. Big numbers for visual is nice. I just wish I could customize those beautiful colors for my routines. I’d like to start a petition to the developers about this feature. I know other things might seem more important, but I REALLY want this feature and as soon as possible.

Great until I switched to iOS 12

I use this to walk/slow trot in intervals. I’ve used it for awhile. In July I discovered Pokémon GO. On my walking/saunter route, sometimes I stop to get in a raid. I used to be able to pause IntervalTimer Pro, fight the raid, then resume my routine. Since I upgraded to iOS 12 (from iOS 10), if I pause IntervalTimer Pro and switch to another app, my routine stops. I was used to that earlier if I had it paused for awhile (like 5 minutes or more), but today I lost my routine when it was paused and I switched apps for maybe 10 seconds, if that.
I went to Deltaworks’ website to try to contact their support rather than mention this in a review, but they don’t seem to have anything listed for support. Additionally, IntervalTimer (free or pro) is not listed on their site.
I also echo a previous reviewer’s comment about available sounds. I’m disappointed some of the sounds were removed. They remain in old routines I created, but I cannot add those same sounds to new routines. I assume that was an IP thing, and sometimes things like that can’t be helped. I miss the human voice announcing the routine is complete (she was replaced by a computer-generated voice). Again, maybe that was a residuals thing and the devs needed to cut some costs. But I miss the human.
I really miss being able to pause for a minute or three, though. If this can’t be fixed, I’ll have to figure out how to force my Fitbit app to do this, or I’ll have to get another interval app.

Perfect for me!

The 4.1.9 update resulted in sluggish responsiveness when using switching between 2 apps. I listen to NPR or watch video during parts of my exercise routine. When I switch back to interval timer it takes several seconds for the timer display to adjust to the end of the exercise. The alert sounds on time. It’s just the display that is sluggish when switching back to it. Previously the display refresh was much quicker. SEE BELOW COMMENTS. THIS REALLY IS AN AWESOME APP THAT DOES EXACTLY WHAT I NEED. I wish the company had a more private way to give performance feedback about the app.

I really like the flexibility of this app. I'm not a gym rat but wanted a way to time and measure a few exercises I do. I don't use the app the way an athlete might but rather use the low and high intensity to time the length of time doing an exercise - for me low intensity is the time exercising and high intensity is my rest time.
The paid version allows me to set up all of my exercises and allows me to easily shorten or lengthen my workout based on the amount of time I have.
I also like the graph that shows each exercise and the amount of time I spent on it. As a repetition and time counter this app is very flexible and meets my need to record and track my workout - even though my exercise is moderate by most standards.
If I could add something to this app in would be an option to show the total amount of exercise time for a particular day.
