Pros and cons of Intervals Pro: HIIT Timer app for iPhone and iPad

Intervals Pro: HIIT Timer app good for

Hi all, I just bought this app and love it. It seamlessly integrates between the iPhone, iPad, and Applewatch. A haptic pulse on the Applewatch would be nice, but I am sure it will come. I recommend going Pro though as you get iCloud backup support. Highly recommended fitness app. Happy Customer :)
Easy to use, easy to modify, and verbal cues work great even while listening to favorite music. You have an option to pay if you want multiple settings- I just change before or during each workout since it is so quick and simple with the free version
This interval timer is pretty good compared to some competitor apps. It has "work" and "recovery" intervals which you can set to any time for both (thats a feature missing from some competitor apps). One improvement Id like to see would be the option to have a countdown timer on one or the other "work" or "recovery" timers. Right now if countdown is turned on it will play on both the "work" and "recovery" timers.
The interval app has helped me ease back into running again. Easy to use and easy to change intervals. Im gradually lengthening running time and reducing recovery time.
I really like the programming flexibility of this app. It makes the app very useful. I also like the fact that it works with whatever music app I choose to use. But I would like a volume control for the voice prompts from the app to adjust the volume level with respect to the music as the prompts are a bit too loud when the music is at my preferred volume.

Some bad moments

I downloaded to use with my apple watch, but it seems that when you have your phone locked, it simply stop working. (Syncing with the watch). Then you miss all the alerts. So basically you need to have your phone unlocked in your pocket all the time to have your watch updating. It also needs to give you the option to not auto start the next circle. So you can use for trainings where you have to move from one equipment to another. Also it needs some help to understand how to make the workout more customizable.
Without phone close to you this WATCH app is useless coz all alerts are on ur phone.
Please check bugs with HR indicator sometimes it doesnt work. And add sound alert on Apple Watch.
No vibration or alert sound on the Apple Watch is a real deal breaker for me!
Is there a way to make the notifications vibrate in the watch? Cant seem to figure that one out. The app on the phone seems to work really well as it is sitting in my gym bag
I didnt even really get to use the app before it malfunctioned and totally started wigging out on my phone. Something definitely needs to be fixed. I tried to do a practice run with the watch and my phone and 1- it doesnt let you pause or start the timer on the watch, which in my opinion totally defeats the purpose of using it on your watch and 2- the watch doesnt vibrate or let you know the interval is done. Please fix!!
