## What is MAC?

The McMaster Premenstrual and Mood Symptom Scale (MAC‑PMSS) was developed using feedback from people who suffered from premenstrual and mood problems, as well as from international experts in the area of women’s mental health, to fill a major clinical gap: The absence of validated tools to assess and accurately diagnose individuals with concurrent mood and premenstrual issues. While the vast majority of the symptom tracking tools out there were never tested or validate through clinical research, the MAC-PMSS has been tested and validated as has been proven to be user-friendly and useful in the accurate diagnosis and assessment of people with premenstrual and mood disorders. The results of its field test can be found here: https://bmcwomenshealth.biomedcentral.com/track/pdf/10.1186/s12905-022-01678-1.pdf 

With the MAC-PMSS app, individuals can track their mood and premenstrual symptoms on a daily basis. The daily symptom tracking, along with information about the menstrual cycle, sleep patterns and possible stressful life events may be shared with your health professional with a simple click of a button! 

The MAC-PMSS application is not a substitute for physician’s advice. Consult a Physician for any medical issues that arise.

### 4/5 — You need to update app coding

*2025-10-28*

So quite a few issues, 

1. typing is completely invisible in text box so you have no idea what you’re writing at all as u type and it’s usually gibberish bc of that

2. The share button doesn’t work I’d say 98% of the time. About 4 times it HAS worked tho. I checked for if there’s an issue with access to photos and files and restarted app and phone but nothing has fixed it for over a week and it’s so random. 

Whoever coded this app seems pretty bad at their job. It has a lot of potential too so that sucks. Didn’t rate it a 2 star only bc I think it’s a great idea theoretically. Apps trash tho. Like a 2003 website w development issues. 

Props to McMaster uni though for coming up w the chart and system and trying. Just pls fire ur coder lol

### 1/5 — Can’t see text when typing

*2022-10-21*

Wherever there is a text box for writing text, you cannot see the text colour because it’s white and the background colour is also white. Please update so you can see the text colour when using the app. Current work around is typing in my notepad and then copy and paste into the textbook in the app. Super annoying.
