About this app

Pearl is a perfect match for you, if

• you want to see your individual hormone levels

• you want to be sure about your fertile days

• you want to track your cycle accurately

• you are trying to conceive

• you are trying to get pregnant with PCOS

• you are looking for a reliable fertile window calculator

• you want to switch to a more accurate fertility tracking method than e.g. measuring basal body temperature or general calendar counting.

Pearl is the only app that accurately measures, monitors and analyzes the hormones responsible for your ovulation. It lets you see your individual hormonal profile and how it changes overtime. You can have insights into your own hormones and actually see how they go up and down.

Hormones are the most accurate predictors for your ovulation and are more reliable than other alleged signs of conception many ovulation tests measure. The Pearl app relies on the actual hormonal information that you measure to give you personalized predictions and safely lets you know when ovulation occurs. If you're wondering how to get pregnant with PCOS and if you have an irregular cycle, Pearl works for you as well!

With the Pearl App you will no longer have to wonder at what stage of your cycle you are, since it comes with a sleek cycle and ovulation calendar view.

You will get the most accurate results using this App together with the Pearl Kit and the urine test strips compatible with the Pearl App. You can easily order them through the App, our website, or on Amazon.

The Pearl Plan is very easy: Pearl tells you in the morning with test to use, take test as you go through your morning routine, take a picture with the App and let Pearl do the rest! It's the easiest way how to know you are ovulating.

Pearl notifies you about your highly fertile days with a clear overview of what you measured and on what dates. Perfect knowing the best time to get pregnant and for planning that miracle.

The new and updated version of the Pearl App makes measuring your hormones easier than ever before, with optional automatic strip detection a new screen where you can view all your testing results.

I installed this app and used it for 2 days. Now today I did the test and it's been 15 minutes, now I'm trying to take a picture and it won't take one even when I do what it says to do. The app also fails to open and has slowed down my phone. Quite disappointed because it may take me over 30 minutes to capture the result but by then it may be false. Great app but the functionality is not good. Deleted the app and reinstalling it may make me lose my data. Not opening when I click on it.

If you wouldn't mind writing to us at or sending us a message in the web chat, it would be greatly appreciated. Thanks, and have a great day.

It's a great app and concept, the only difficulty is that sometimes the lines on the test strip are super hard to see in the photos. I still think it'll be worth the money for sure! (Updated after 3 months of use->) I'm not sure I'll buy it again. It's better than Clearblue's ovulation detector, BUT 1) The automatic detection for the strips won't work on my phone 2) A ring for the timer 3) hormones chart's cycle n° and ovulation predicted is simply inaccurate. (It predicted it during my period)

Thank you for your kind review! The lines reflect the hormone concentration in urine, thus when hormones are high or low the lines on the test will change. Pearl takes care of the measuring with the camera and smart algorithms to ease the work for the human eye. The manual option lets you select the lines, while the auto capture finds them for you.

I feel like app itself should give you more information, like how to read the graphs, tips, advice, etc. around fertility. The timer in the app doesn't chime when the 15 minutes is up, so I've forgotten a few times to take photos of the strips. I also do not receive notifications, I'm not sure why as my notification settings are on.
