problem corrected promptly

UPDATE: the developer’s quick response and prompt correction of my complaint detailed below has encouraged me to give this app a 2nd chance. i do like the simplicity and versatility of this timer that allows me to store my own personal HIIT timer sequences, so fingers crossed that it remains the app that i have counted on for so long. ORIGINAL COMPLAINT: i have been using this app since 2013 and (as others have noted) had no problem ignoring the banner ads at the bottom.... until now. the latest version interrupts me every time i complete a sequence, try to resume or interact with the app during a workout and forces me to sit through 5 seconds of noisy ad before i can make it go away. i am furious and downloading a different app so i can discard this horror immediately.

Love it. Simple to use. Awesome

I was looking for a basic and simple to use app that acts like a 30sec timer for my exercise routine. This app is awesome! I was able to easily customize it to count down and ding every 30seconds. I liked how it changed colors every 30 seconds cuz sometimes my volume is muted so I can glimpse at the color change to kno that it’s times up. I love the display on my iPhone, its not cluttered like some other apps. I’m soooo happy I found this app after trying out many others and i like how it’s free :) I’m definitely gonna recommend this to my friends. Some negatives: it costs money to add this to my Apple Watch, so I’m just going to use the free iPhone app version instead (until I win the lottery haha). I don’t like the ads. And last complaint is, I wish the music controls on iPhone was larger. Some positives: I love how i now push myself to workout harder and longer cuz i try to keep up w the timer. And I like how I can now focus on breathing rather than Focusing on counting. Love this app!! Thank u developer for making me healthier and more motivated to workout :-)

Great for all sorts of interval training

I originally got this to use for timing Fartlek runs and speed intervals. The cycles are easy to customize and provide great feedback through sound and vibration. But then I started doing interval training at home (circuit, HIIT, and technique drills). Now I could add in visual keys and create complex hour long workouts and practices. Colors, sounds, titles, intervals, rests, cycles, repeats, all are customizable on the free app. If I could add one feature, it would be either a three period cycle or a cycle start warning, so that I can do high/low/get ready or left/right/rest. If I could make one change, it would be the ability to make a one time premium purchase instead of a subscription. I would like to put some money towards the app, perhaps for new templates (like the suggestion above) or for sharing, but I am wary of subscription services over one time purchases.
That said, I now use the premium service and is has even more flexibility, to the point that I use it over even physical timers at the gym.
