Could be great, BUT crashes often

I want to LOVE this app, but I can’t. So I currently use it & Kindara & enter the basics in to the Fitbit app, so it reminds me when my period will start. I was thrilled when Marquette Method finally came out with an app, but it is not all it should be! We have been using MM since the birth of our surprise 5 year old & the Method it amazing...the app should be too! I am a busy mom of 4 & rarely get to enter my start date on day 1...this app HATES that, it crashes when I try to change my start date. We are essentially phase 3 only since we are strictly TTA, so it isn’t the day number so much as the PPHLL that I need, so I’m still using it, but because it does not work well & does not show real cycle days for past cycles, I cannot give up Kindara.
It hasn’t been updated in a LONG time, please update to fix the crashing & many other bugs mentioned in the reviews!

Love this app!

I haven’t had any real issues with the app crashing like others have said. Sometimes if I try to change things from a previous day it mess with the app. I appreciate the way I can enter in everything and it’s visibly all there. One person said the choice to choose condom or withdrawal is against church teaching and should t be an option. If you choose that choice, it lets you know that not a form of NFP and that if your having difficulties with this method to contact and NFP counselor!

My only complaint about the app is I’ve had times I forgot to restart my cycle and it has issues understanding if I’m already days into my cycle, so I’ve had to delete a whole cycle these throwing off the way my cycles look overall.

Bugs make it nigh unusable

This app is really buggy. The most annoying set of bugs center around trying to enter the last 5 cycles of data. It's actually impossible to do this. The minute you enter an old cycle date it flips out and makes you end the cycle. And it doesn't even calculate the cycle length correctly unless you put in some data for the last day.

I almost sent this as in-app feedback, but that doesn't work either!

Two stars because once the bugs are fixed, it'll be nice to have an app specifically for Marquette. But only two stars because the execution is embarrassingly sloppy.
