• 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.

The app works with Apple Health.

Slave Kay ,

Great for multiple peaks!!!!

So I was really disappointed at first when my chart didn’t look like they normally do. I wasn’t sure if it required higher levels to show up or if the tests defective as all of my tests were low and I usually have 3 peaks every cycle. My fsh did still rise like usual 3 times whereas my LH was stagnant. Until my actual ovulation! It helped me pinpoint which one of my crazy peaks was actually the right one! I don’t recommend trying to transfer these tests to another app they don’t transfer values correctly. It also doesn’t update your fertile window if you ovulate later than their projected BUT your chart still will be enough. I have to use 1.5 boxes a cycle due to longer cycles (35-45 days) and highly recommend getting more if you do as well but don’t stop testing if your levels are low to begin with!
