Most women spend so many years actively trying not to get pregnant that it never occurs to them that getting pregnant might take some time. Because of this, it can be a hard pill to swallow when that first month of trying (or those first several months) doesn’t result in a positive pregnancy test.

When that happens, a lot of women find themselves searching for answers and tools that might help to make the next month a success. Then there are the women who don’t want to get pregnant, but would also prefer to manage that naturally. Thankfully, there’s an app for both situations! Actually, there are several. Here are the best ones out there this year.

Clue Period Tracker

If you’re looking for a better understanding of your body and cycle, who better to look to than one of the top obstetrics and gynecological organizations?

Kindara

Android rating:
4 stars Free

Kindara calls itself the “most sophisticated fertility app available.” It pairs with a wireless basal body temperature thermometer to make charting a breeze. Using advanced analytics, Kindara claims to help users identify health conditions that could be preventing pregnancy (like PCOS) as well as to simply become more in tune with their own bodies. To assist in achieving this goal, the app also aids in tracking cervical changes, PMS symptoms, spotting, moods, and doctors’ appointments.

Period Tracker

iPhone rating:
4.5 stars Free

If you’re looking to predict your future periods and ovulation cycles, this may be the app for you. Period Tracker syncs your upcoming 12 periods and fertile days (with predictions based on your previous periods) to help you plan into the future. This makes it easier to plan everything from vacations to doctor’s appointments around when you might be most fertile — and to avoid making big plans when you might be dealing with that uncomfortable period bloat.

Fertility Friend

This is an app that not only tracks your periods and ovulation days. It also helps you recognize the signs your body provides that you may be ovulating. Fertility Friend is intent on empowering women with knowledge. The app really is that friend you might be looking for while trying to conceive — the kind of friend with an extensive knowledge base who can help you figure out exactly when you’ll be most fertile.

Ovia Fertility

You’ll need a basal thermometer for measuring your temperature every morning.

Conceivable

iPhone rating:

This is not a simple period tracker. Instead, the Conceivable app is part of a broader program aimed at helping women identify the underlying cause of their fertility issues and combat them in order to become pregnant naturally. The app works in conjunction with their program, guiding women with a natural wellness approach.

Dot

iPhone rating:
4 stars Free

Dot utilizes a patent pending method called Dynamic Optimal Timing. The app calculates your individual conception risks for each day of your cycle. There’s a sophisticated algorithm involved that shows you instantly whether you’re at low, medium, or high risk for pregnancy on any given day. This information can then help you avoid or try for a pregnancy. Your unique cycle is analyzed, but there’s no need for complex charting or additional hardware.

Period Tracker Lite

iPhone rating:

Period Tracker calculates the average of your past three months’ menstrual cycles. It only requires you to input the start and end of your period in order to provide predictions for the future. You’re able to take notes regarding menstrual symptoms, weight, and temperature changes for your own records or to share with your doctor. You can even add custom symptoms and moods.
