Calculate your period and predict your next menstrual cycles.Wouldn’t it be great to look into the future and see when your next period is coming up?

We made a period calculator that learns about you and your cycles. Smart Period Calculator uses a sophisticated machine learning algorithm to predict your period over the course of the next few months.

Jet another period calculator? Not really. Almost all period calculators out there are complete garbage. Why? Because they usually ask you for your average cycle length and do a very basic calculation by adding the average length over and over again.

Have you noticed that your natural cycle isn’t always exactly 28 days long? It’s a myth that the female cycle is always 28 days long.

From a medical perspective, if your cycles’ length is between 23 and 35 days, your cycles are considered regular.

We made a better period calculator, which predicts your next periods based on your individual previous cycles and your individual period duration. These individual factors are combined with a general statistical model we derived from over 80,000 female cycles.

In other words: Our period calculator gets to know you. It learns more about you and your cycle as you enter more data.
