While backing out, I got permanently locked out of the app. My email isn’t recognized, my password isn’t accepted, and there’s no other access. Garbage for functionality. Just use the internet. ### 2/5 — Great idea however super glitchy *2024-06-08, version 2.1* App is probably great, but it is super glitchy and crashes a lot. The developers need to go back and fix some fundamental bugs to make it more dependable then the App is a 5 star app ### 1/5 — Outdated *2024-05-28, version 2.1* App hasn’t been updated for 2 years, not user friendly at all on an iPhone. Wouldn’t recommend, we switched to Huckleberry and it’s much better. ### 1/5 — App does not track properly and crashes *2024-04-14, version 2.1* This app does not track properly. I had tracked diapers one day, and then they showed up on every day, even days that hadn’t happened yet. The app also gives error codes while trying to log items. Definitely needs updating. ### 1/5 — App does not work *2024-04-12, version 2.1* Downloaded the app as it was highly recommend by our nurse, however it does not even open! ### 1/5 — Cannot open app *2024-02-02, version 2.1* Just downloaded and signed up via gmail. Press app on phone and it doesn’t open. ### 1/5 — App - Not Working? *2023-10-23, version 2.1* Just had a baby this pst weekend and would love to use the app, but it crashes about 9/10 times of use. Cannot login to the system to even use the activation code. Developers- please fix this app. ### 1/5 — Was working *2023-04-12, version 2.1* This app was working but now it hasn’t been working for the past 24 hours. It says “Error. Canceled” when opened and there is no way to put in a ticket for customer support or app bug. So I’m hoping writing a review will get someone’s attention. ### 1/5 — Garbage *2022-12-06, version 2.1* None of the audio on the videos works ## Frequently asked questions about Period of PURPLE Crying ### What is the Period of PURPLE Crying app?
