+1 for option to try it out without email sign-up. I hate it to sign-up everywhere (for trial access as well) with my emails. I went directly with this option.<p>I haven't heard about the pomodoro concept, but it sounds interesting and I definitely want to try it out. Your app looks like a nice way to start.<p>I feel there's still some work on the design part to be done as currently it looks very "plain".<p>What are the options - novice, intermediate, advanced in the settings? Also, how much does your service cost?<p>If you want feedback from more people, you can try our give & get feedback platform, <a href="https://usability.testing.exchange" rel="nofollow">https://usability.testing.exchange</a>.<p>Good luck!
