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.

The only way to track hormones daily
I purchased this because I suspected a hormone imbalance since coming off desogestrel. It has been very helpful in showing what is going on with my cycle and so far has confirmed that I appear to be suffering with low progesterone in the luteal phase. It is an expensive device (particularly if you use it for several months) and people should be mindful that it doesn’t guarantee pregnancy. However, if you suspect you have a hormone imbalance it is very valuable to be able to measure hormones daily. Female cycles change throughout the month so getting a one off snapshot from a blood test often isn’t very helpful. Getting a consultation to explain your results is another added expense. It would be helpful if the app contained more information and examples regarding cycles and results. For example, I have noticed my hormones sometimes spike up and down from day to day and I would like to know if this is normal. All in all I would recommend.
Good concept but expensive and wasteful wands and an annoying bug
If there is any interruption when connecting to the analyser after testing, it then won’t transfer test results. Tried restarting analyser and app, and no, that’s it for the day it just won’t transfer the data and it has to be inputted manually. Please fix this bug. Otherwise the user experience is good, I just hate the idea of throwing out all of the plastic and microchips on each wand.
Constantly Being Logged Out
We have a main account and a partner account.
The main account is logged in on ONE device and partner account is logged in on a separate device, once.
Yet both accounts keep being logged out when relaunching the app.
It might not be today, but give it a day or so and it’s logged out.
Sort it out. It is beyond annoying.
PCOS - 23 weeks pregnant
After trying to regular ovulation sticks and nothing showing up due to my low hormone levels, I was so delighted to spot my “surge” via the Mira app. It took some months to get used to my cycle which was very irregular but I honestly credit this amazing technology with helping us get pregnant.
For anyone unsure about their cycles or who doesn’t look like they are ovulating on regular sticks this is definitely worth a go.
One thing I would say is I tried the more basic sticks first, I wouldn’t bother with those. Just go for the top level sticks which show more hormones. They are the ones that helped us and we ended up wasting money on the regular ones and then not using them.
Currently 23-weeks pregnant with our first baby, praying everything continues well but already in a position we weren’t sure we would be. Thank you team Mira!
Brilliant devise
Great devise. Brilliant to see actual numbers for hormones. Conceived the first try. Sadly ended in miscarriage but happy with product. Feels the best at home devise for irregular cycles and pcos.
Helped me see if I’m able to ovulate
Really accurate, best purchase ever!

Temperature
I think that when you log temperature it should also appear on the curve graph. That would add an extra star.
The new app is terrible
I loved the app and device up until they updated the app recently. Now it’s awful! It’s really hard to understand even when it’s working but mine is now so glitchy It completely missed the fertile window which is the whole point of having it in the first place.
Please do something urgently about the app Mira or this will have been a total waste of money.
Doesn’t function properly
Total malfunction on unit, then customer service operator was totally patronising.
Only once did the machine score over 1 unit of LH which had me in a a spin and panic, then decided it wouldn’t read any of the wands...I inserted over 30 wands in one sitting and it just kept reading failed try again or use a new wand. The wands are not cheap, when I reported it to CS the response was ....we only recorded two fails at our end !!!!! I have a stack of wands to prove it, but you know what I’d rather just have someone understand that at 42 the months are fertility are precious....! 😉
