Without hormones, it's bound to be less reliable than the pill.

A well-followed sympto-thermal method reaches effectiveness rates comparable to hormonal contraception — reliability comes from careful observation, not from hormones.

It's too complicated, you need to be an expert to make sense of it.

The app does the sorting for you: log your observations in a few seconds, and it interprets them and shows you where you stand.

Everyone knows natural methods just don't work.

That reputation belongs to the calendar method (counting days). Sympto-thermal methods, which combine several body signals, are a different method entirely — considerably more reliable when followed properly.

In practice, it's always the woman who ends up handling it alone.

That's true when the tool doesn't make sharing easy. The app is built precisely so both of you can check and contribute, not just one person filling it in alone.

Natural methods don't protect against STIs.

That's true, and we won't hide it: these are fertility-tracking methods, not protection methods. Outside an exclusive, tested relationship, condoms remain necessary.

It's too demanding, you have to think about it every single day.

Any tracking method needs regularity. The app is designed precisely to keep that effort to a minimum: a few keywords, a notification, and you're done.

That's a religious choice, it's not for me.

Couples choose natural methods for all kinds of reasons — health, environmental concerns, personal or religious conviction. The app is for everyone, whatever brought you here.

One observation a day, a clear calendar, live sharing with your partner. Here's what fertility tracking with natural methods actually looks like.

The case for and against

Seven subjects that often trip people up — and what each side says about them.

Comparison of the arguments for and against natural methods, subject by subject.
For What natural methods give you	Against What we hear most often
1No hormones
For No synthetic hormones to take: your natural cycle is neither altered nor masked, and you learn to read it as it actually is.	Against “Without hormones, it's bound to be less reliable than the pill.” Our answer : A well-followed sympto-thermal method reaches effectiveness rates comparable to hormonal contraception — reliability comes from careful observation, not from hormones.
2Knowing your body
For Observing your temperature, mucus or cervix daily means learning to recognise your own cycle's signals — a skill that stays useful for life, through pregnancy or menopause.	Against “It's too complicated, you need to be an expert to make sense of it.” Our answer : The app does the sorting for you: log your observations in a few seconds, and it interprets them and shows you where you stand.
3Real reliability, if used properly
For Structured sympto-thermal methods (temperature, mucus, cervix) are scientifically validated, and far from the reputation of the old calendar method.	Against “Everyone knows natural methods just don't work.” Our answer : That reputation belongs to the calendar method (counting days). Sympto-thermal methods, which combine several body signals, are a different method entirely — considerably more reliable when followed properly.
4A couple's matter, not just hers
For The calendar syncs live between both partners: each of you can see where the cycle stands, and nobody is left out of the loop.	Against “In practice, it's always the woman who ends up handling it alone.” Our answer : That's true when the tool doesn't make sharing easy. The app is built precisely so both of you can check and contribute, not just one person filling it in alone.
5What it doesn't do
For In a stable, exclusive relationship, not adding hormones or a daily device is a real relief for many couples.	Against “Natural methods don't protect against STIs.” Our answer : That's true, and we won't hide it: these are fertility-tracking methods, not protection methods. Outside an exclusive, tested relationship, condoms remain necessary.
6A daily discipline
For Observing takes about 5 seconds a day once it's a habit, with a reminder so you never forget.	Against “It's too demanding, you have to think about it every single day.” Our answer : Any tracking method needs regularity. The app is designed precisely to keep that effort to a minimum: a few keywords, a notification, and you're done.
7In line with your values
For For those looking for an approach that matches their convictions, without a device or hormones, natural methods also answer that search for consistency.	Against “That's a religious choice, it's not for me.” Our answer : Couples choose natural methods for all kinds of reasons — health, environmental concerns, personal or religious conviction. The app is for everyone, whatever brought you here.

Our conclusion

No method is magic, and natural methods take real learning. But read both columns again: most objections are about the discipline they require. Every argument in favour is about what you gain from truly knowing your body.
