Pregnancy & Fertility

Fertility Friend has been helping people get pregnant since 2003. It looks like it. The interface is dated, the design is cluttered, and none of that matters because the BBT charting and ovulation detection are the most accurate in the category. Tracks temperature, cervical mucus, OPKs, and 40+ signs. Free with 30-day VIP trial. VIP from $24.99/yr. If you're serious about TTC, this is where r/TryingForABaby sends everyone.

Premom is the first fertility app that reads ovulation test strips with your phone camera. Take a photo of your OPK, get a numerical LH reading instead of squinting at lines. Tracks cycles, predicts ovulation, logs BBT. Free basic version with OPK scanning. Premium adds advanced analytics. Also sells their own test strips and BBT thermometers. For the TTC parent who wants data without guesswork.

Clue is the research-backed period and fertility tracker built with UC Berkeley, Harvard, and MIT partnerships. Gender-neutral design, no pink flowers, no cutesy language. Free version tracks 200+ cycle factors. Clue Plus (~$39.99/yr) adds 12-month predictions, analysis views, and an FDA-cleared contraceptive feature. If you want a period app that feels like a medical tool rather than a lifestyle brand, this is it. 10M+ users.

Natural Cycles is the first and only FDA-cleared app for use as birth control. You take your temperature every morning, the algorithm identifies your fertile days, and tells you whether to use protection. 93% typical use, 98% perfect use effectiveness. Three modes: Birth Control, Plan a Pregnancy, and Follow Pregnancy. Annual plan $119.99/yr includes a thermometer. Also works with Oura Ring and Apple Watch for overnight temperature. Not cheap, but cheaper than most contraception over time.

Glow Nurture is the pregnancy piece of Glow's reproductive health suite. Free version covers due date calculator, weekly baby development, symptom logging, and weight tracking. Premium ($60/yr) adds comparative insights ("is this normal?"), premium articles, and priority support - and works across all Glow apps (fertility, pregnancy, baby). The ecosystem play is the real selling point. If you already use Glow for cycle tracking, Nurture continues the data.

Ovia is the pregnancy tracker that's often free through your employer's health benefits. Basic version covers weekly development, symptom tracking, food safety lookups, kick counter, and contraction timer. Employer-sponsored premium adds health coaching, personalized content, and programs for specific conditions. No ads, no paywalls if your company participates. Check with HR. If your employer doesn't sponsor it, the free version still works but you'll find more features in [Flo](/flo-period-pregnancy-tracker) or [Glow Nurture](/glow-nurture).

The Bump is a free pregnancy app with interactive 3D baby models, daily content, baby name finder (with origin, meaning, and popularity trends), and direct registry integration.

Premium ($49.99/yr) removes ads and adds AI health assistant, video courses, symptom checker for PCOS/endometriosis/fibroids, and detailed pregnancy tracking. FSA/HSA eligible. It's the safe mainstream choice - not the most specialized at anything, but covers everything from first period to perimenopause.

Week-by-week pregnancy updates, milestone checklists, expert articles, and a community of millions. Kick counter, contraction timer, birth plan builder, baby photo journal - all free. Around since 1997, available in 6 languages. More of a content hub than a data tracker - if you need to log feeds and diapers, use Baby Connect or Huckleberry.
