I see! Thanks a lot, this is great food for thought. I'm currently focusing on MVP to see if this is somewhere useful but this sounds like the sort of thing that could follow up.
Thanks for the feedback. The intention is to quickly show 'how long normally the cycle is' and 'how deep we are in it'. Agreed some research time could take you quickly to the same conclusion but every user is different.
Is there anything that I could add to make it more useful for you? This is exactly the sort of feedback I'm after!
Thanks for the comment! As an Android user I'm less familiar with the behaviour of iOS users. Is this something you think an iPhone user would find useful or check before buying? Happy to add if it were the case.
