Pearl Fertility is a fertility app you can use to monitor your hormone levels via urine (pee) testing to track your menstrual cycle. This may help with conception by identifying potentially fertile days. You can precisely map your hormonal cycle by using a purchased test kit (FSH and LH from urine/pee sample each morning). The app will notify you about your highly fertile days – information that potentially increases the likelihood of planned conception. The app uses artificial intelligence to detect Pearl strips via phone camera. Inbuilt timer to allow for test strip to develop.

Note: This app specifically states it is not to be used for contraceptive purposes, and also advises you to seek medical advice if you have not conceived within 6 months.

PROS	CONS
✔ Nicely designed app that is easy to use. ✔ Handy to have ability to use artificial intelligence (AI) to scan testing strips, to minimise risk of user error. ✔ Clear graphical description of chances of getting pregnant (small, some, good or high). ✔ Uses scientifically sound information to allow for accurate monitoring of hormonal cycle.	✘ It is noted on the website that Pearl has been tested in a clinical setting in the US and approved by an independent review board. However the results have not been published as yet, so there is no available data to support use. ✘ Progesterone testing strips are not included in the Pearl Fertility kit, but the app is compatible with a particular brand (purchased separately) to confirm ovulation has occurred. ✘ Some user reviews describe issues with functionality, eg, app camera not working to detect testing strips. However, it seems the support team worked with users to help solve these issues.

Clinical review

Reviewer: Dr Arna Letica, GP
Date of review: April 2021
Platform: Android
Version: 1.5.466
Comments: Pearl Fertility app allows users to map their hormonal cycle by using purchased test kit (FSH and LH from urine sample each morning). The app will notify users about their highly fertile days, information that potentially increases the likelihood of planned conception. This app is useful for females wishing to conceive, as they can monitor hormone levels, track their cycle and calculate their fertile window. It is also designed to be used by people with polycystic ovarian syndrome (PCOS), who may have an irregular cycle. Overall I think this is a well-designed app which would be useful for females trying to conceive and wanting to optimise knowledge of their cycle and fertility awareness. The testing kits are a necessary additional expense, and Ovulation Detector kits are available from other providers so this could be an alternative. However, I think there are many users who will appreciate the ease and convenience of this app and the features it offers.
Safety concerns: None. This app specifically states it is not to be used for contraceptive purposes, and also advises users to seek medical advice if they have not conceived within 6 months.
New Zealand relevance: Yes, can be used by New Zealand users.
