When you are trying to conceive (TTC), the "best" app depends heavily on how you want to track your data. Simple calendar-estimation apps often get the fertile window wrong if your cycle fluctuates, whereas apps that accept real biological inputs (like basal body temperature and hormone strips) provide much higher accuracy.
The top-rated apps among trying-to-conceive communities break down by tracking style:
Fertility Friend: Widely considered the gold standard ("the OG") by communities like Reddit's r/TryingForABaby. It has an older, utilitarian interface, but its analytical engine is unmatched if you track Basal Body Temperature (BBT) and ovulation predictor kits (OPKs). It doesn't guess based on a rigid calendar; it waits for your actual biological data to confirm when ovulation actually happened.
If your goal is getting pregnant, my top pick is —especially if you want more than a simple period calendar.
Premom: Exceptional if you plan to use cheap quantitative or qualitative LH ovulation strips . The app allows you to take a photo of your ovulation test strip, reads the dye intensity, and graphs your surge levels numerically, making it very user-friendly for pinpointing your peak day.
Flo: One of the most visually polished and popular apps. While its baseline predictions rely on a calendar algorithm, it handles symptom, cervical mucus, and positive OPK logging well, and integrates smoothly with lifestyle tracking. (Best if you prefer a modern interface and aren't doing rigorous temping).
Read Your Body: A favorite for those practicing formal Fertility Awareness-Based Methods (FAM) . It is completely customizable, non-algorithm-driven (it doesn't interpret your data for you—it lets you analyze it yourself), and privacy-focused.
Inito / Ovia:Inito pairs with a physical hardware monitor that tracks actual hormone concentrations (Estrogen and LH) on test strips, while Ovia offers great customizable data logging and supportive community features.
To help narrow down the best fit, tell me:
Are you planning to track basal body temperature (BBT) , use LH ovulation test strips , or just track calendar dates and symptoms?
Do you prefer a simple/clean interface or deep data analytics?
If you're trying to conceive (TTC), I’d look for an app that does more than simply predict your period—ideally it should let you track ovulation tests (LH), cervical mucus, and/or basal body temperature (BBT).
My shortlist
Natural Cycles — best if you want a data-driven approach using temperature and fertility algorithms. It has a specific “Plan Pregnancy” mode and is FDA-cleared for contraception in the U.S.
Fertility Friend — particularly useful if you want detailed BBT charting and like analyzing your cycle data.
Premom — especially useful if you're planning to use LH/ovulation predictor strips, since it can record and analyze test results.
Clue — a good choice if you want a more general period/symptom tracker with fertility information and a strong emphasis on privacy.
Flo — polished and easy to use, with a dedicated trying-to-conceive experience, though it is broader than a specialized fertility charting app.
One important point: no app can reliably pinpoint ovulation on its own for everyone. ACOG notes that fertility apps vary in quality, and evidence about their usefulness is limited. Cervical mucus and LH testing can give you more useful information about the fertile window than relying solely on a calendar prediction.
For actually getting pregnant, the fertile window is roughly the 5 days before ovulation through about 1 day afterward, with the highest chances around the days immediately preceding ovulation. Sex every day or every other day during that window is generally recommended.
If you tell me whether you have regular or irregular cycles, whether you want a free app, and whether you're willing to use ovulation strips or a wearable, I can narrow it down to the most suitable option for you.
The "best" app depends heavily on how you plan to track your ovulation (calendar math vs. quantitative data like basal body temperature and LH strips). The top-rated apps for trying to conceive (TTC) excel in different areas:
Fertility Friend (The Data King)
Best for: Chart-nerds who use basal body temperature (BBT) and ovulation predictor strips (OPKs).
Why it’s great: It looks a bit retro/outdated, but its algorithm is widely considered the gold standard for pinpointing ovulation accurately. It doesn't just guess based on calendar math; it analyzes your physical signs.
Cost: Free basic version (more than enough); VIP upgrade available.
Premom (Best for Quantitative OPK Strips)
Best for: People who love using cheap LH strip tests.
Why it’s great: It allows you to take a photo of your ovulation test strips with your phone camera, and the app's scanner grades the darkness/ratio (low, high, peak) to log your surge automatically.
Cost: Free with in-app features.
Natural Cycles (Best for BBT/Algorithm-Driven Insights)
Best for: Users tracking daily basal body temperature (syncs smoothly with a smart thermometer or Oura ring).
Why it’s great: It is FDA-cleared and gives you a very straightforward daily red/green fertility status. It has a dedicated "Plan Pregnancy" mode.
Cost: Subscription-based (paid monthly or annually).
Flo or Ovia (Best for Beginners/User-Friendly Interface)
Best for: Those who want a gorgeous, highly polished app and prefer a simpler calendar or basic symptom-logging approach.
Why it’s great: Extremely popular, easy to use, and packed with great educational content and community forums. Note: If you only use calendar mode without logging physical signs like cervical mucus or LH tests, predictions can be off.
Cost: Free with a premium paywall for advanced insights.
To help narrow down the ideal match for you , let me know:
Are you planning to track basal body temperature (BBT) , use LH strip tests (OPKs) , or just rely on calendar/cycle dates?
Do you prefer a free app or are you open to a paid subscription?
If your goal is specifically getting pregnant, I’d look for an app that does more than predict ovulation from your period dates. Calendar-only predictions can be off, while tracking LH/ovulation tests, basal body temperature (BBT), and cervical mucus gives you more useful information. The American Society for Reproductive Medicine notes that calendar-app predictions have important limitations.
My shortlist
Premom — particularly useful if you use ovulation predictor kits (OPKs). It can photograph/interpret test strips and chart LH results, making it practical for actively trying to conceive.
Fertility Friend — a strong choice if you want detailed BBT charting and cycle analysis rather than a very simplified app.
Ovia Fertility — good if you want a free, comprehensive tracker with BBT, cervical mucus, symptoms and fertility-window information.
Natural Cycles — best suited to people who want temperature-based fertility tracking, including wearable integration. It's FDA-cleared for contraception, although its conception/“trying to conceive” use is a different goal.
Flo — a polished, easy-to-use option if you want straightforward cycle/TTC tracking rather than highly detailed fertility charting.
If I were choosing based specifically on TTC: I'd lean toward Premom if you're willing to use LH test strips, or Fertility Friend if you want detailed charting. The app itself matters less than having good biological data—the fertile window is roughly the 6 days ending on ovulation, and intercourse every 1–2 days during that window is associated with the highest pregnancy rates.
If you tell me whether your cycles are regular, whether you're willing to use ovulation strips, and whether you want free-only apps, I can narrow it down to the best 1–2 options for you.
When you are trying to conceive (TTC), the "best" app depends heavily on how you want to track —whether you prefer a simple calendar prediction, detailed data charting, or quantitative hormone tracking.
The top-rated apps for conceiving, categorized by what they do best, include:
Fertility Friend (Best for Data & Charting)
Why it's great: Widely considered the gold standard by communities like Reddit’s TryingForABaby , it doesn’t rely on a generic 28-day calendar math guess. Instead, it uses your actual data—Basal Body Temperature (BBT), cervical mucus, and ovulation predictor kits (OPKs)—to build a custom chart and pinpoint when you actually ovulate.
Interface: Retro/old-school, but unmatched in algorithmic accuracy.
Cost: Very functional free version; cheap annual upgrade for advanced stats.
Premom (Best for Digital OPK Strips)
Why it's great: If you use cheap, dip-and-read ovulation strips (like Easy@Home), Premom lets you take a photo of the strip with your phone. Its OCR technology automatically reads and scores the line darkness (LH levels) and plots your hormone curve on a graph in the app.
Interface: Clean, visual, and specifically tailored for tracking LH surges.
Cost: Free, with optional premium upgrades.
Flo (Best for Ease of Use & Beginners)
Why it's great: Flo is massive, incredibly polished, and user-friendly. While basic versions just track cycle length, you can log positive OPK tests or symptoms to refine its predictions. It also transitions seamlessly into a pregnancy tracker once you get your positive test.
Interface: Modern, sleek, and visually appealing.
Cost: Free basic tier, but heavily pushes a paid subscription for full insights.
Natural Cycles (Best for Temperature-Based Tracking)
Why it's great: Powered by a certified algorithm that analyzes daily basal body temperature shifts, it has a specific "Plan Pregnancy" mode. It identifies your peak fertility days with high precision based on your personal biomarkers rather than calendar averages.
Interface: Minimalist and very intuitive (uses a green/red day system).
Cost: Subscription-based (comes with a basal thermometer).
Mira or OvuSense (Best Hardware + App Combos)
Why they're great: If standard apps aren't cutting it because you have irregular cycles or PCOS, dedicated hardware trackers like the Mira Fertility Monitor (which measures actual quantitative hormone levels in urine) or OvuSense (overnight core body temperature sensor) sync directly into their proprietary apps for clinical-grade accuracy.
To help narrow down which one fits you best, tell me:
Are you planning to track Basal Body Temperature (BBT) and ovulation strips (OPKs) , or do you prefer just tracking your period dates and cervical mucus?
If you’re trying to conceive (TTC), the “best” fertility app depends on how much data you want to track. Apps that only predict ovulation from period dates are convenient, but apps that let you log ovulation predictor kits (OPKs/LH tests), basal body temperature (BBT), and cervical mucus generally give you more useful information for timing intercourse.
Here are strong options:

Best for: Basal Body Temperature (BBT) and serious symptom charting.
Why it’s loved: It might look a bit retro/clunky, but its algorithm is unmatched for accuracy. If you input data like BBT, cervical mucus, and ovulation predictor kits (OPKs), Fertility Friend pinpoints your actual ovulation date rather than just guessing based on calendar math.
Best for: Using cheap quantitative/qualitative ovulation strips (LH tests).
Why it’s loved: You can take a photo of your ovulation test strip inside the app, and it automatically reads, grades, and logs the LH spike level to track your surge clearly over time.
Best for: A clean, modern interface with general cycle and lifestyle tracking.
Why it’s loved: It has a dedicated "Conceive" mode, is visually friendly, and gives great daily insights. However, if you have irregular cycles, its calendar-based predictions can just be an educated guess compared to temping apps.
Best for: Pairing with a basal thermometer or Oura Ring/Apple Watch data.
Why it’s loved: It runs on a precise FDA-cleared algorithm that detects temperature shifts to confirm ovulation has happened. (Note: It requires a subscription).
To help narrow down the ideal choice, let me know:
Are you planning to track basal body temperature (BBT) or use ovulation test strips (LH tests)?
If your goal is specifically getting pregnant, I’d pick Fertility Friend as the best overall app—especially if you’re willing to track more than just your period.
My top picks
🥇 Fertility Friend — best overall for TTC
Excellent for charting basal body temperature (BBT), cervical mucus, ovulation tests (OPKs), symptoms, and intercourse.
Particularly useful if you want the app to help you confirm when ovulation actually occurred, rather than simply predicting it from your cycle history.
The interface is less polished than some competitors, but the fertility-charting capabilities are excellent.
🥈 Premom — best if you're using ovulation test strips
Especially convenient if you're taking daily LH/ovulation tests because it can analyze photos of the strips and track their progression.
Good choice if you want a more straightforward, visual approach.
🥉 Natural Cycles — best for temperature-based tracking
Uses daily temperature measurements to determine your fertile window.
More automated, but it's a paid service and requires consistent temperature tracking.
Clue — best for privacy and a clean interface
Great general cycle tracker, but I'd choose Fertility Friend or Premom if conception/ovulation timing is your primary goal.
One important tip
An app's predicted ovulation day is only an estimate. ACOG notes that there isn't a foolproof way to calculate fertile days, and recommends intercourse every day or every other day during the fertile window when trying to conceive. OPKs and cervical-mucus observations can make timing more useful than relying on an app's calendar prediction alone.
If I were choosing a setup for TTC:Fertility Friend + inexpensive LH ovulation strips is probably the combination I'd start with. You can add BBT if you want stronger confirmation of ovulation.
If you tell me whether your cycles are regular or irregular and whether you're willing to use ovulation strips/BBT, I can recommend the best app specifically for your situation.
The "best" app for tracking fertility and ovulation depends entirely on how deeply you want to track your data and whether you prefer an app that does all the guessing for you or one that teaches you to read your body's literal signs.
The top-rated apps for trying to conceive (TTC) fall into a few distinct categories based on community consensus and clinical reputation:
Fertility Friend (The Gold Standard for Data/Charting): Highly recommended by communities like Reddit's r/TryingForABaby as the absolute most accurate tool. It has an older, utilitarian interface, but its algorithm is unmatched if you are tracking Basal Body Temperature (BBT), cervical fluid, and ovulation predictor kits (OPKs). It doesn't just guess your fertile window—it actually teaches you how to interpret your charts.
Flo (Best for Ease and General Tracking): One of the most popular apps globally. It has a gorgeous, user-friendly interface and a dedicated "TTC Mode." It relies heavily on calendar math and your logged symptoms, making it low-stress and very straightforward if you have relatively regular cycles.
Premom (Best if Using Cheapie Ovulation Strips): This app is specifically designed to sync with cheap quantitative LH (ovulation) test strips. You take a photo of your test strip inside the app, and it numerically scores the darkness of the line to help you precisely pin down your peak surge.
Natural Cycles (Best for Temperature-First Tracking): An FDA-cleared app that relies primarily on daily basal body temperature tracking (often syncing with a smart thermometer or wearables like the Oura Ring). It is clinically validated and has a dedicated "Plan Pregnancy" mode that shifts from a contraceptive lens to a conception lens.
Clue (Best Clean/Privacy-Focused Tracker): Features a dedicated Clue Conceive mode that shifts predictions toward maximizing the fertile window. It is scientifically backed, straightforward, and avoids overly cutesy marketing.
To help narrow down which one fits you best, tell me:
Are you planning to use ovulation test strips or track your basal body temperature (BBT) , or do you just want a simple calendar prediction?
Its Plan Pregnancy mode identifies your most fertile days rather than simply assuming a standard 28-day cycle.
It uses basal body temperature (BBT) plus cycle information and can incorporate ovulation-test results.
You can collect temperature data with compatible devices such as Apple Watch, Oura Ring, or WHOOP, rather than necessarily taking your temperature manually every morning.
It has a strong clinical/regulatory background: it's FDA-cleared in the U.S. as a contraceptive app, although you're specifically using its pregnancy-planning mode here.
Ovia is a good choice if you don't want to buy a subscription or wearable. It gives you a fertility score and predicted fertile window, and lets you log things such as BBT and ovulation tests.
If you're actively trying to conceive, I'd use Natural Cycles + LH ovulation strips. The app can identify your likely fertile window, while an LH test gives you an additional hormonal signal that ovulation is approaching.
One important distinction: an app predicts your fertile window; it doesn't guarantee that you've actually ovulated. If your cycles are irregular or you're having difficulty conceiving, combining app tracking with LH tests—and sometimes clinical ovulation testing—can be more informative.
If you tell me your average cycle length, whether your cycles are regular, and whether you want a free app, I can tell you which app/setup I'd choose for you.
Fertility Friend: Widely considered the gold standard ("the OG") by communities like Reddit's r/TryingForABaby. It has an older, utilitarian interface, but its analytical engine is unmatched if you track Basal Body Temperature (BBT) and ovulation predictor kits (OPKs). It doesn't guess based on a rigid calendar; it waits for your actual biological data to confirm when ovulation actually happened.
