HIIT app - Feedback highly appreciated 🙏

Just a couple notes from my observation.

-The copy could use work all around. For example: "A simple and clean UI allows you to quickly configure and launch your favourite workouts and get right into burning those calories." To start, "A simple and clean UI" is not a statement the avg consumer will understand, nor is it what they feel is providing the experience you're describing. It's also a very wordy statement that will have more impact if you reduce the word count. I would suggest something more along the lines of "Spend less time building workouts and more time burning calories." Every statement you make on the page should add value to your pitch.

-It's not entirely clear how some of this works. The information you presented doesn't answer the question of how I configure the workouts, what my options are, what specifically does the voice coach do, are there visual cues or not... and these are all common features easily understood in competing applications. I would get ahead of that and present more in those areas.

I bought Intervals Pro a few days ago. Congratulations on the App Store feature. That's amazing. As I also make an app I'd love to read a post about your work on the project so far and the lessons learned.

The website is simple, but nice. The App Store page and screenshots as well.

I'd cut the value prop to "Spend less time configuring workouts and more time burning calories".

I tried the app. Look and feel wise I like it a bit more than Intervals Pro. But the feature set doesn't work for me.

I need distance based intervals. And I need to add multiple different rest and intense intervals. E.g. 2x800m, 4x400m, 8x200m. Your app works for my Tabata workout though. But maybe you can differentiate yourself for people, who want an easy and focused experience and not this level of customization.

As a user I don't like the premium UX. I can't try how the speech assistant works without buying. But I want to know if it works for me before I buy. And the same with other features. I'd prefer to e.g. try the speech assistant 5-10 times to see if the app works with my workout. Then I'd have to buy it. And if not I save money and time. But if I have to buy to try I might just not try. Or I buy it and try and see it doesn't have distance and then I am angry. And the angry customers write you a 1* review as you know.
