Multi-award-winning period education for teens
I always felt ashamed speaking about my period. Now I can read the articles in the Teena app with my mom and we speak about it.
When I think of my period coming, I feel powerful and proud. I also feel a little nervous and have lots of questions. Teena answers all of my questions.
I love my Teena and measuring in the morning is so easy and fast. I told all my friends about Teena.
Before Teena I was worried about getting my period in school. Now I know when my period is coming and I am prepared.
Predict periods reliably
Teena uses basal body temperature (BBT) to track hormonal fluctuations in the menstrual cycle.
After detecting the slight increase in BBT with ovulation, Teena predicts when the next period is likely to arrive (including the very first period).
Empowering teens with peace of mind that they won’t be caught off guard.
When the time comes, they’ll be ready.
*Disclaimer: Because teen periods are irregular, Teena can’t give an accurate to-the-day prediction for every single period. Teens may have bleeding that looks like a period but isn’t linked to menstruation.
Your teen’s new BFF for her morning routine
Learning to love the cycle
Teena is all about period positivity.
Because menstruation isn’t just a fact of life that needs to be endured – it’s a beautiful part of our biology signaling health and vitality.
“I am learning so much and can speak to my mom about it” and more reviews from happy teens
Before I got this Teena period tracker, I felt really nervous about when my period was going to come, and if I would be ready or not. But now, all I have to do is track my temperature using my Teena every morning, and I feel like I’m going to be ready when my period comes. It will catch when I ovulate, even before my first cycle. Now I feel confident because I will know when my period is coming.
I was upset when I got my period because I thought it was the end of the world. It was an inconvenience because I never knew when the next one would come. Now I know and I can prepare.
