The Mira app is fantastic. It gives you your fertility levels and even a number! It could not be easier or clearer than this. I've been using it for over 1 month now and I can't be without it anymore.

With Mira, I found out that my ovulation was much later in my cycle than most of the apps predicted. Really love it so far!

It’s great to see how different hormones change throughout the cycle and get much more accurate results than your usual app-only cycle predictions.

I've always had irregular cycles, and the Mira app is already helping me understand some aspects of my cycle I've never considered before.

The app is so comprehensive, and I do enjoy entering my data, unlike other period tracking apps I use.

Creates more stress and anxiety then it is helpful. It will not sync the test results no matter if I follow all the instructions, connect before inserting the wand, and leave my phone on next to it while it counts down for 20 minutes. After it still hasn't synced the data even though it says it's connected. I follow all the troubleshooting tips, then the final tips clear the data from the analyzer. Wasted testing wands. No manual data input option. Just stress

There's an extensive amount of data you can view, collect, or output about your cycle, it's quite impressive. There's a few things that are not intuitive, like getting started on subscribed orders and viewing those orders from the app. HUGE downer was finding out you HAVE to have Internet just to view your daily results. Hauled all the stuff on internat'l travel w/o cellular or WiFi, and I couldn't even see my daily info. Very dumb. And the updated bright green color is gross... pale was better.

The app has been great for the last 6 months. Today, it completely crashed and is only showing a blank white screen that says, "There is something wrong. Please contact support." I tried uninstalling and reinstalling the app and restarting my phone, but there's no change. The app is doing the same thing on my boyfriend's iPhone. My history and chart seem to be completely gone. Clicking the contact support button lets me start a chat with Ai, but the message doesn't go anywhere. Very frustrating.
