Mother-Daughter-Bundle (Daysy & Teena)

The Daysy & Teena Mother-Daughter Bundle pairs a Daysy fertility tracker for mum with a Teena period tracker for her daughter. With two separate devices and their companion apps, you can each build a better understanding of your menstrual cycle, at your own stage of life.

What's included in the Daysy & Teena bundle?

• One Daysy fertility tracker, for basal body temperature tracking and fertility awareness.
• One Teena period tracker, designed to help tweens and teens learn about their menstrual cycle.
• Access to the free DaysyDay and Teena companion apps.

Daysy fertility tracker: understand your cycle

Daysy uses your basal body temperature and menstruation entries to calculate your daily fertility status. Its self-learning algorithm draws on menstrual cycle data to help you recognise your individual cycle patterns, with a simple colour display on the device.

Each morning, upon waking, measure your temperature under your tongue for approximately 60 seconds and record menstruation when applicable. This gives you a practical routine for getting to know your cycle.

• Basal body temperature tracking with an under-the-tongue measurement.
• A colour display for your calculated daily fertility status.
• The free DaysyDay app to view cycle details and share information with your partner or healthcare professional.
• Bluetooth data transfer to compatible phones and tablets.
• A rechargeable battery with USB charging.

Teena period tracker: cycle confidence for teens

Teena combines a basal body temperature tracker with a free educational app for tweens and teens. A temperature measurement takes approximately 30 seconds. Teena uses temperature data to provide cycle insights and predictions of the next period, helping your daughter prepare rather than rely on calendar dates alone.

The Teena app includes an animated Cycle Journey, expert-written educational articles, information about anatomy and puberty, and period self-care tips. Your daughter can also record emotions and symptoms to explore patterns in how she feels throughout her cycle.

• A period tracker designed for tweens and teens.
• Cycle insights and next-period predictions based on temperature tracking.
• Age-appropriate learning about periods, puberty and the changing body.
• Daily tips, symptom tracking and emotion tracking.
• No name or email address required to use the Teena app.
