Effective although Sluggish

I've been using this app for over two years after reading the book TCOYF. I'm very happy using the FAM method, and this app does what it needs to do. My main complaint with the app is that it tends to be slow...slow to log me in, slow to enter new data, and slow to pull up my chart. As soon as I save a new data point (BBT for example) the app shuts me out for a few seconds while it shows the dreaded "updating cycle information" progress bar and I can't enter additional info during that time. I wish that it would wait to do this until the app has been inactive for, say, five seconds so as not to interrupt me. It's especially problematic when I'm entering my BBT in the morning (before I'm fully awake), because I tend to fall asleep again while I wait to be logged in! To get around the sluggishness, I was hoping to create a shortcut using Workflow or Launch Center, but sadly ovagraph isn't compatible with these apps. It would also be nice if it could integrate with iOS's Health app. Overall I give four stars because I'm grateful for the app being free and without ads, and I do recommend it. These are just my suggestions for the developers to further improve. I know there are many similar apps out there, but I'd rather not switch away from ovagraph after having used it for so long. Thank you and please keep updating! :)

Thanks for the feedback! A good internet connection will help your app log you in and sync quickly, so do check on that. Feel free to reach out to our support team for any additional tips/tricks to get the most out of charting with OvaGraph - we're happy to help!:

Quality customer service

I was using this app for a month and everything was great. Then with the next cycle the app started to slow down. It stoped synchronizing my current data with the chart and the app became so slow in general, it was too painful to use. I contacted their customer service and got a replay the next day. They asked me to check if I have good internet connection and did I scroll down the page to make sure the page was completely visible. I’ve been doing it all along, so I knew it was not the problem. I responded to them with more details and my assumptions on this issue. The following day I could see that something was adjusted within my account and the app had to get rid of some data duplicates through updating itself. Once that was done, Voila! The app went back to normal fast working program, showing my chart with all the information.
Thank you for the excellent customer service! I’ll keep using this app and enjoy it’s convince.

I have been using this app alongside working with a fertility doctor to get pregnant. I appreciate that it allows me to feel a bit more in control and knowledgeable about my body.

However, I find the app much more confusing to use than necessary. Inputting data is fine, but figuring out how to do anything else is a hassle. There’s a laundry list of FAQs in the app, but it’s the FAQs for the mobile app and regular website - which is more confusing than helpful. It would be helpful if there was an actual page that explains everything, so when you start using the app you know how to customize things, figure out the language you all are using (abbreviations, etc), how different components of the app and charting are referred to, and take advantage of all parts of the app - which I’m sure I haven’t because it’s impossible to know how to do or where to find anything.

Also, I’ve been wondering this for months - what do the numbers in the BBT circles on the chart mean??? I can’t find the answer anywhere.

Thanks for your note! Why don't you send an email to our team so we can get you pointed in the right direction to utilize everything the app has to offer!: They'll be able to point you to the FAQ about where to find what the circled BBT readings are too!
