Best period app

I love this app! The graphics and color are wonderful. You can pick your own skin color for the app. I like the labeling and the accuracy. I just wish that I can transfer all my data to my new phone! I should be able to log onto any device with my email and get all of my history!!!!!! Therefore losing a star... I don't mind the ads because it's a free app. I love that I can keep track of my love connection and write notes. Also you can tailor notifications for fertile week and period week. I've looked through all the other period apps and the configuration is so weird. This is the best one! PLEASE KEEP THE HISTORY so I can continue to use this great app!

Way to lose a long time user 😕

I've been using this app for years. It's followed me through my unsure teen years, and birth control changing my body in ways I didn't know it could, all the way into my adult years, and all the way had been a well used app, and normally fairly accurate. Now I've opened up the app only a few times since the new update....and my thoughts? Well it looks and feels just like all the other period tracker apps that I've dropped in the past. annoying useless stuff cluttering the screen, and a million options to jump through just to log my information. And on top of all of that, I've noticed that the last period I logged (which happened to be a few days early) has since been on my calendar and recorded in my cycle. BUT THE APP STILL SENDS ME A REMINDER EVERY NIGHT SAYING THAT I AM SO MANY DAYS LATE! WHEN IT SHOWS THAT I AM ACTUALLY 4 DAYS IN. even after my period had ended and I'm midway through my cycle, it still keeps notifying me that I'm late. All in all, these days I really only use the app as a sort of comfort blanket. I typically know when I'm starting and the app is just reassurance that I'm not off my game. So with so many in app disappointments, and after reading so many recent upsetting reviews, I think it's long time for me to say goodbye to my period buddy. Goodbye iperiod.

Disappointed in changes

I’ve used this app for several years. It had some nice features and I liked that it easily worked for me when I was pregnant too. However, I’m extremely disappointed with the fact that they now charge a subscription fee for features that I used free of charge for years. I understand upgrades and adding more options for your customer and I even understand why that would cost the customer $. I don’t understand though why you would not continue to offer the basics for free when they had been available for years without charge. I would have been able to overlook this annoying issue and just switch to a different app without complaint, but I’ve literally lost YEARS of data that I can no longer access because I’m not willing to pay a subscription fee. At the very least, I should be able to view my own data from PAST years without paying for that too. I dealt with infertility, miscarriages and several other health issues all well documented on this app and to not be able to access any of that information is incredibly frustrating. Sorry, but even if I were willing to pay for these features, I wouldn’t be doing it with this app anymore.

Developer Response ,

Dear Tis' so sweet, So sorry for any confusion with the subscriptions. The subscriptions introduced new features that you did not have in the past, but are not necessary just to view your data. It sounds like you need some help with your account if you are not seeing your data. I will be happy to help you if you email us at support@winkpass.com. Thank you!
