Best forClassic fertility charting from temperature, cervical fluid, and ovulation tests.
- Who it's for
- People who want a free chart on the web or in the iOS and Android apps, and who will decide later whether VIP is worth paying for.
Fertility Friend's how-it-works page says you record basal body temperature, cervical fluid, and other optional signs, and that ovulation prediction kits are a signal for luteinizing hormone. It says the app builds a chart and marks fertile days. The homepage says you can use it on the web, iOS, and Android, and that it integrates with Apple Health and Oura Ring. The company says it has offered charting since 1998 and cites over one million pregnancies. Those figures are the company's. A chart is an estimate from what you log. It is not a clinical diagnosis, and the pages checked do not describe FDA-cleared birth control.
Pros
- The how-it-works page names basal temperature, cervical fluid, and ovulation prediction kits, and the homepage names Apple Health and Oura.
- The membership page says the account is free, with 30 days of VIP features, no credit card, and no auto-renewal.
Cons
- The membership page did not print a VIP price, so the cost after 30 days is on their site, not here.
- A fertile-day chart is the company's analysis of what you logged. It is not a clinical diagnosis, and the pages checked do not call it FDA-cleared birth control.
