What fertilityfriend.com does
Fertility Friend, operated by Tamtris Web Services Inc., is a cloud-based fertility tracking platform founded in 1998 and headquartered in Ontario, Canada. The platform serves primarily women trying to conceive through cross-platform applications (web, iOS, and Android) that combine basal body temperature charting, cervical fluid tracking, and proprietary ovulation-detection algorithms with optional data ingestion from Apple Health, Fitbit, Oura Ring, and—added in 2025—Ultrahuman Ring AIR. The company is independently owned, bootstrapped, and operated by a small team of PhD scientists; it claims to have facilitated over one million pregnancies across a user base of millions of women globally and holds a 4.8 app-store rating.
The business model is freemium with a VIP premium membership as the sole revenue stream. The free tier is fully functional for tracking and automatic ovulation detection, while the VIP tier adds privacy-enhanced forums, advanced analysis tools, and educational content. Notably, VIP is sold without auto-renewal—users purchase discrete time periods via Stripe, PayPal, Paddle, or in-app purchases on the Apple App Store and Google Play Store. The company explicitly states it does not monetize via advertising, referrals, or data trading, reinforcing a privacy-first positioning that has become strategically relevant for U.S. consumers in the post-Dobbs environment and is reinforced by Canadian data hosting.
Complementary products extend the core offering: a standalone offline iOS app (Menstrual Calendar FMC), browser-based ovulation and pregnancy-chances calculators, a Test Line Reader for analyzing OPK/HPT strips locally in-browser, community galleries containing 240,000+ shared charts and 43,000+ test photos, and an educational content library spanning courses, eBook, podcast, and tutorial videos. The company has no disclosed external funding rounds, no reported M&A activity, no public leadership disclosures beyond the legal entity, and a headcount described only as a team of PhD scientists within a 1–10 employee range.

fertilityfriend.com competitors and assessment
Company assessmentDirect peers
- Natural Cycles: Natural Cycles is an FDA-cleared digital contraceptive and conception app using BBT and algorithm-driven fertility detection. It directly competes with Fertility Friend's ovulation-detection core, with the added advantage of regulatory clearance and a paid-only model.
- Flo Health: Flo is the largest women's health app globally (380M+ users) covering period, ovulation, pregnancy, and perimenopause. It directly competes with Fertility Friend in the ovulation/fertile-window tracking category while offering broader adjacent coverage.
- Clue: Clue is a Berlin-based period and fertility tracking app with 12M+ MAUs. It directly overlaps Fertility Friend on cycle tracking and ovulation prediction, with stronger brand investment and a science-forward positioning similar to Fertility Friend.
- Glow: Glow is a fertility and menstrual tracking app with conception and pregnancy support. It directly competes with Fertility Friend on the trying-to-conceive journey and shares a freemium subscription model.
- Ava: Ava sells a clinically validated fertility-tracking bracelet that captures skin temperature and other physiological signals. It overlaps Fertility Friend's BBT-based fertile-window use case and competes for the same trying-to-conceive customer, but with a hardware-centric model.
- Premom: Premom is a free period and ovulation tracker with a strong focus on OPK test photo analysis and BBT charting. It directly overlaps Fertility Friend on the trying-to-conceive journey with a more aggressive free tier.
Broad incumbents
- Kindbody: Kindbody is a fertility clinic network with a digital front door for cycle monitoring and patient management. It addresses an adjacent layer of the same journey (clinical fertility treatment) where Fertility Friend users eventually escalate.
- Fitbit / Google Health: Fitbit devices capture temperature and cycle data and surface fertility insights in the Fitbit app. As a wearable partner it routes data into Fertility Friend, but its first-party cycle tracking represents a substitute path for users.
- Apple Health: Apple Health is a default platform layer that aggregates cycle, sleep, and temperature data and increasingly surfaces fertility insights natively. It is both an integration partner and a long-term platform risk to standalone fertility apps.
Emerging players
- Oura: Oura's smart ring tracks skin temperature and sleep and increasingly surfaces cycle/fertility insights natively. It is a key wearable integration partner for Fertility Friend but is also a partial substitute as it builds first-party fertile-window detection.
