The Best Ovulation Tests for Fertility Tracking

The human egg cell contains a nucleus with half the number of chromosomes needed to make a baby. Every human female is born with one million of them, according to Cleveland Clinic— but only 300 to 400 of them will ever be ovulated. During each menstrual cycle, hormones flood the ovaries and one of the lucky egg cells emerges. If you were to somehow witness that event, you could watch it happen without the aid of a microscope. Egg cells are one of the few human cells that are large enough to be seen with the naked eye.

Signs of ovulation are diverse and vary from woman to woman. Some experience a heightened sense of smell, but others feel increased sensitivity around their nipples and breasts. A mild achy feeling on one side of the lower abdomen– called Mittelschmerz– is another indication. Libido changes, light spotting and stretchy, clear cervical mucus are common as well.

Since the majority of ovulation signs are hard to concretely identify and track, many women use ovulation tests to predict and plan out the most fertile days of their cycle. Many different types of ovulation tests exist, ranging from simple but effective LH (Luteinizing Hormone) test strips to apps that can process many different ovulation data points simultaneously and more.

Here are the best ovulation tests you can buy:

The best digital ovulation test system

Clearblue Digital Ovulation Test

Clearblue’s Digital Ovulation Test contains an optical test strip reader, which analyzes your results and outputs either a smiley face “yes” or an empty circle “no” symbol. This design is intended to make it easier to use compared to regular test strips, which can often be hard to interpret.


  • No need for guesswork. The digital screen displays a straightforward “yes or no” answer.
  • Reusable reader. After you run out of test strips, you don’t have to buy a new device– just strip refills.
  • You don’t need an app to use it. Since the optical reader and display is built into the device itself, it’s all you need to get started.
  • Works faster than ordinary test strips. Most LH test strips require you to wait about five minutes, but Clearblue can deliver a “yes” result in just three minutes.
  • Identifies the two most fertile days of your cycle. It detects only your ovulation day, but also the day directly before you ovulate.
  • 99% accuracy. As long as you use your Clearblue properly, there’s only a 1% chance that it will give you the wrong answer.


  • Expensive compared to ordinary test strips. It costs more than twice as much as ordinary ovulation test strips and you get less than half as many strips.

In a nutshell

The Clearblue Digital Ovulation test is somewhat pricey compared to ordinary LH test strips, but that extra cost could be worth it if you’ve tried regular LH strips before and you struggled to interpret your results.

Easy@Home Ovulation Test Strips

When it comes to determining your ovulation date, more data is better. Most home ovulation tests rely exclusively on LH testing strips. Easy@Home Ovulation Test Strips kit comes with LH testing strips, but it can process other data points as well. An optional thermometer lets you enter your basal body temperature statistics into the app. You can also enter PDG (Progesterone) testing strip results, as well.


  • Takes BBT (Basal Body Temperature) into account. The Easy@Home app’s algorithm can factor in BBT data when it makes ovulation predictions.
  • PDG data can also improve accuracy. For even more precise results, you can take progesterone readings and enter those results into the app.
  • Interprets your strip tests for you. If you snap a picture of a test strip, the app will analyze it and record your results.
  • You can throw away used test strips. Once a strip’s data is recorded in the app, there’s no need to keep it.
  • Charts provide a big picture view of your cycle. Use the app’s chart feature to understand your ovulation patterns.
  • Optional BBT thermometer. The base kit only comes with LH (Luteinizing Hormone) test strips, but there’s another version of the kit that comes with a BBT thermometer.


  • The photo scan function doesn’t always work. If the lighting isn’t perfect, the app won’t be able to read the test strips.

In a nutshell

LH strips are extremely accurate, but errors made during use can throw off results. In addition, their indicator lines are sometimes hard to interpret. This ovulation test kit from Easy@Home addresses these issues by providing the ability to track multiple data points.

The most user-friendly ovulation test strip

Wondfo Easy at Home Self-Checking Ovulation Kit Test

Wondfo is one of the few LH strip manufacturers that’s confident enough in their product to offer a satisfaction guarantee. One reason for that could be that the lines on strips turn dark more consistently compared to other LH strip brands. This is helpful for people who haven’t used an LH strip before, since it eliminates the time needed to learn how to make accurate ovulation predictions.


  • Easy-to-understand results. These ovulation test strips won’t leave you wondering whether or not you’ve reached ovulation day.
  • Line darkens as ovulation approaches. The indicators are more effective because they usually turn all the way black.
  • Each strip comes in its own individually sealed pack. You can carry as many strips as you need in your pocket or purse, wherever you go.
  • Low wait time. After you submerge the strip in urine, you’ll find out your results in three to five minutes.
  • Reasonably priced. The 50-pack costs roughly the same as what other ovulation test strip makers charge.
  • 99% accuracy. They almost never produce an inaccurate result.
  • Satisfaction guarantee. Wondfo both accepts returns and issues refunds.


  • No option to buy a 100-pack for a discount. Most test strip makers give you a lower price if you buy 100 strips, but Wondfo doesn’t.

In a nutshell

The key benefit of Wondflo’s LH strips is clearer results lines. If you’ve tried LH strips before and gave up because you got weak or hazy lines, Wondflo may be worth a try. If you aren’t completely satisfied, alert Wondflo’s customer support team and pick up a full refund.

The best smart ovulation test app with a pregnancy test feature

Femometer Ovulation Test Strips Kit

The app that comes with Femometer’s Ovulation Test Strips Kit can read not only LH strips, but also HCGH (Human Chorionic Gonadotropin) test strips, as well. Human Chorionic Gonadotropin is sometimes called “the pregnancy hormone” because it is secreted by the placenta. The app’s scanner is handy because it takes the guesswork out of the equation when evaluating results.


  • The app can read both LH and HCG20 strips. This lets you track your ovulation cycle and test for pregnancy.
  • A more accurate way to interpret your results. Instead of eyeballing your strips when you plot out your ovulation schedule, you can scan your strips with Femometer’s convenient app.
  • You can throw away your strips after you scan them. Once you’ve finished logging your strip, you don’t have to keep it for tracking purposes.
  • Delivers results in ten minutes or less. Ten minutes after exposure to urine, the test strips will be ready to read.
  • 99% accuracy. The strips meet industry standards and are accurate nearly all of the time as long as you use them properly.
  • One-year warranty. The warranty isn’t a complete satisfaction guarantee, but it does cover all manufacturing quality-related issues.


  • Difficult to interpret the results without the app. The indicator lines on Femometer’s test strips often don’t turn completely black.

In a nutshell

Other smart ovulation test apps have more features, but Femometer’s offering is a bit more price effective. If you like the idea of scanning your test strip with your phone but aren’t really interested in other bells and whistles, this could be the best kit for you.

Buying guide for ovulation tests

Key considerations


LH strip tests that meet industry standards are extremely accurate and only fail to detect a surge of LH 1% of the time. However, there is a caveat: an LH surge doesn’t necessarily mean that your body actually released an egg. Also it’s often hard to pinpoint when the LH surge is happening. For better accuracy, try an ovulation test that can analyze multiple prediction methods– like basal temperature tracking, for example. This way, you can supplement your monitoring routine, improve your tracking accuracy and correct for any errors or discrepancies.

Pregnancy testing

Some ovulation tests ship with both LH strips and HCG20 pregnancy test strips, but others contain only the LH strips. Check the product description to find out which type of strips come in the box.


Some companies offer ovulation test kits that contain accessories like BBT (Basal Body Temperature) thermometers, which can help you better understand your ovulation pattern.

Indicator line darkness and clarity

After you apply urine to an LH strip, you will see a line appear after about ten minutes. The darkness of the line corresponds to the level of LH in your urine. Some LH strip indicators turn all the way black ahead of ovulation day, but others only reach a few shades short of black.

App availability and features

Some ovulation test makers design apps that can do things like scan your test strips, help you log your physical ovulation symptoms, view charts and more. Other ovulation tests are just simple strips or devices that contain built-in electronic components that can read the results.

Size and portability

Most LH test strips are individually wrapped, so that you can take them with you and use them without drawing attention. Since test strip packs are quite small, they also slide easily into a pants pocket. Digital ovulation tests are slightly bulkier, but they’re also quite slim and travel well in a purse.

Quality assurance

Manufacturers of quality ovulation tests inspect them in the factory. This reduces the chance of defects and helps improve the odds of getting an accurate reading every time.

Vendor reputation

Some ovulation test sellers send out test strips that are nearing their expiration dates. To avoid purchasing an expired ovulation test kit, read about the seller online and learn more about their reputation before you commit to making a purchase.

Satisfaction guarantee

When an ovulation test seller is willing to back up their product with a satisfaction guarantee, that’s usually a good sign. The satisfaction guarantee will let you receive a refund or replacement in the event that the product doesn’t work properly.

Price ranges


Since you can get a 50-pack of simple LH surge testing strips for around $15, they’re the cheapest way to track your ovulation patterns. Larger packs cost more, but the bigger pack of strips you buy, the more you’ll save over the long run.


Ovulation tests kits that feature apps with features like automatic results scanning usually cost a bit more. Other typical ovulation test app features include charts, reminders and calendars. Expect to pay roughly $20.


Digital ovulation tests kits are the most expensive. All their electronic components are included on the unit itself. They cost around $30, on average.

Frequently asked questions

Q: When is the best time to begin tracking my ovulation pattern?
A: Try to start around day 11 of your cycle. This will allow you to take multiple readings ahead of your ovulation day. As you continue to test yourself, you’ll be able to get used to the way the LH strip indicator lines look. Some LH strips indicator lines turn all the way black when the surge occurs, but others don’t.

Q: What factors can affect an LH strip test’s accuracy?
A: If you have polycystic ovaries, you may see an LH strip even if you don’t release an egg. Hypothalamus and LH production irregularities can skew the results as well.

Q: What’s the optimal time to try for a baby?
A: You should plan to have intercourse on the day that you see the LH surge line begin to fill in. The appearance of a line means that your LH levels are high. That means that an egg is probably about to drop.


  • Try not to urinate for about four hours before you take your sample. Too much water in your urine may distort your results.
  • For best results, try to take two LH readings each day. If you don’t have time for two, one should suffice.
  • A positive LH test result will not fade with time. However, negative results sometimes cause a faint line to appear after 20 minutes have passed.
  • An LH test can only confirm an LH surge, not an actual ovulation. For more accurate planning, consider using a basal body temperature thermometer.
