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 :-)

Good App with Intrusive Video Ads and Deceptive Seller

The app has annoying video ads as of late, but is otherwise very good.

I've been using the app for years to time and track my daily physical activity routines. However, every now and again the seller decides it's time to try and milk it a bit more, and pushes out an update that adds more aggressive ads, and it's never in the update description, of course. For instance, the December 2019 (version 4.2.1) update added video adds at the end of every routine, but the update description was "We are happy to introduce a new in-app purchase to let you remove the Ads. Removing the Ads is just an option for those users hope to remove it and not mandatory. It doesn't change the way you used Interval Timer before. Just grab what you need. This new version is worth you update because we also fixed some bugs to make it more stable."

It is possible to circumvent the video ads by turning off cellular data for the app and disconnecting from WiFi, but it's far from ideal.
