How unique do you have to be? ,

Awesome!, but how about some features for “change of life”?

This program is excellent, i’ve been using it for well over a decade. Feature rich, but also useful and efficiently navigable if you only use a fraction of the features. My daughter is going through menses and she’s already getting familiar with the app to better learn the rhythms of her own body. Ironically, I’m somewhere between Peri-menopause and menopause. Here’s my ask. Sometimes periods/spotting really are very close together but not an “extension” of a period due to wack-a-doodle hormone patterns. Can we please get an option that lets us designate a rare close-occurrence as an extension of a period OR as a separate menstrual event? That would be very helpful!

The new settings on this app is confusing! I’ve been using this app since 2015 and this is the first time I’m lost. March was fine but since the app changed it’s layout, I’ve been trying to figure out how to log my period for April. After logging my cycle that lasted from April 6th - April 9th, the app keeps telling me I’m 23 days behind on my period (what da heck?!?). After trying to re-log it several times, it’s now saying my next period is in 21 days, then it says my next period is in 3 days which are both incorrect!! It’s also making me log my feelings/mood/period flow, etc. for each day which is annoying. I’ve never had to do so much work to simply log my cycle. It’s frustrating because right now, it’s not giving me the accurate date of when I should expect my cycle to begin for the month of May. All of the new icons and emojis are really cute and helpful, BUT the app was very simplified before, so I’m not sure why all of a sudden a need to complicate it. It just should not be this annoying to simply log my monthly!!! Before, I was able to tap on a date and the app would ask if it’s the first day of my period and I would simply click yes. Then I’d be able to tap on the last day of my period and select yes for the end of my cycle. PLEASE, PLEASE fix this ASAP!! This has always been a great app, please simplify it like it was before. Thank you so much!

Logging periods

Logging periods has become quite confusing. What’s wrong with logging first day and last day? I preferred having the calendar easily visible from the home screen and in the click of a button my cycle is updated. Instead, if I click “Edit Period” from the home screen it takes me back to my last cycle.... why would I need change that when I’m trying to log the first day of my new cycle? Or I have click the calendar and then either Log Cycle or Edit Cycle appears and then a click to set up the whole cycle on day 1... also doesn’t make sense since on Day 1, I don’t necessarily know how long it will last.
I’ve been using this app since 2012. Previous upgrades have been very helpful and made necessary adjustments. It was also easily adaptable but this one in early 2020 just took a big step backward and I’m still struggling a couple months later and have already unintentionally edited last months cycle interfering with my data’s quality and integrity. I know this sounds stereotyped, but I have a weird feeling a bunch of men without medical degrees were behind this upgrade.
