The Problem

Don’t worry—you’re not alone. (Not even close.) The average woman is only actually fertile for about five days per cycle, and fitting getting busy (ahem) into your busy schedule can turn such an exciting, pivotal moment in your life into just one more stressful chore scribbled at the top of your to-do list.

Your body produces hormones when you’re fertile that can be sensed in your urine. However, these tests just replace one set of worries with another. Reading tiny test strips and keeping exhaustive charts (probably stuck to your fridge, waiting to be discovered by friends you aren’t quite ready to tell about your plans) is a full time job. Digital tests are an improvement, but still demand careful + constant recordkeeping. (←Not ideal.)

The Solution: We’re Here To Do Better.

The Eveline uses an easy, discreet clip-on attachment for your phone to hold test strips in front of your camera, where our app can automatically measure your fertility with pinpoint accuracy.

It also keeps track of your previous results, and crunches those numbers in a powerful learning program to discover your personal biological rhythm, giving you a heads-up of upcoming fertile days (whether or not you set up a countdown clock like a moon rocket is up to you). Leave the thinking to Eveline, and we’ll leave the fun to you.

3 Fertility Level Display

Eveline's patented technology uses your front-facing cell phone camera and light to measure changes in color when our test strips are exposed to luteinizing hormone, a key marker of ovulation. Our adaptive algorithm software turns that data into a simple, three-tiered snapshot of your fertility in the moment.

Test Records

Our app securely stores all your test results. The smart algorithms use your test results to build a fertility profile, highlighting the future days when it’ll be easiest to start your new family.

Our Fertility Calendar with real-time results gives the dates you're most likely to be fertile.

Easy To Use: Eveline Removes All Your Stresses in 3 Easy Steps.

Use the simple urine test a few days after your menstrual period. Our OB-GYN-recommended strips can detect the surge of LH level, which is the ovulation indicator.

The handy clip-on reader that is attached to your smartphone’s front camera will automatically analyze the results and record them in the app for future tracking!

The app will take care of the rest. You will be duly notified to re-take the test in order to confirm the results. Finally, you will be reminded in advance that your fertile days are coming up! From then on, it’s up to you!
