A few bugs.

First off before I criticize this app I must say it is still an app on my phone and I use it and it is very handy and is the best period tracker I've used. Now there is one bug. When I start my period the app sill says I'm late. And everyday of my period I have to manually click on each and everyday I'm on it, and it keeps saying can not change can not change, or it will delete my Previous day of starting my period, or it will think I started my period everytime. It does not manually count I have to click each and everyday from start to end my period, or it will say my period lasted 1 day. So I kinda have to fight with it to get my start to end date correct. It just a little bug. Idk how to fix it. Or if it is indeed supposed to do that. Other than that I love the app and a little fighting is worth keeping it on my phone.

3 babies in 4 years and done!

Using this tracker I successfully planned 3 pregnancies in 4 years. I liked that it gave a range of ovulation days, so we knew which week we should be "trying" on. Each time it was accurate because only once did it take us more than 2 months of trying. And one time it only took the one try. Perhaps we are just really fertile, but it was good to know when I would be fertile so we could also plan not to get pregnant in between babies. Now I'm done with baby making and I use it to track my period just so I know when it's coming and I like that I can add notes about my emotions and how heavy the flow is on each day.

Pretty good

I love using this app because I know when to start preparing for my period. There are a couple minor things though. First of all when I got this app I was so confused on how to use it. When I was on my period it said like "19 days left" or something and I thought "My period will end in 19 days?" I have figured this out though. So it would be nice if you could do a small tutorial video. Second of all, I applied a password but a couple months later I tried logging in and it said my password was incorrect and I know I did it right. I had to delete the app and download it again. Not sure if this is normal or not. But still I like it and would recommend it to friends. 👍
