Love it - Please update for 6sPlus support

I Love this app. So much that even tho it hasn't (yet) been adjusted for the 6Plus / 6s Plus screen size, I'm still giving it 5 stars. Very easy to set up long, multi-cycled workouts, and I can see at a glance where I'm at in a set. I think the color bundle was worth the Buck spent on it too. I get to invert the text colors, etc, or set other schemes for, (for example) the 7th & last set of a Tabata-style exercise for a motivational factor. I took literally, 2 minutes to save a session consisting of:
5 rounds of Tabata workout. After each of the 5 rounds I set 30 seconds each for a Turkish Get-up left, then right, then 2 minutes "active rest". I got to running on there, but that's just 1 example of what's possible.
** Dev's: Please update **

Love the app, but prefer the old version

I love this app. The timer is great, the color choices to differentiate the times, the buzzer choices and the ability to play music are all great. I do not however like the new update. I liked knowing what was completely by next. I used to put my choreography in the timers and would know what the next activity was while doing the previous activity. Now I have to wait a few seconds to read the activity or put what is coming up next on the current activity. (I hope that makes sense) Please bring back the option to see what is coming next.

Great App for keeping track of time intervals

I have used the original plastic GymBoss and I figured that they also had the phone app, so downloaded it and gave it a whirl.

So far, had no issues with app, it has a clean streamlined interface, easy to use timers and create them (you can remove timers by swiping timer name to left and hitting delete, fyi to some peeps), and allowing you to choose titles and select colors for intervals is great for visual checking.

Would be nice if different alarm sounds could be individually set for each separate intervals/colors to help differentiate them.

Overall, have no issues with free App and will consider buying pro upgrade to support the developers. Great job!
