Red Zone exists because most period tracker apps are built for one person. We built one for two.
Menstrual cycles affect mood, energy, intimacy, and how people experience stress — yet most partners navigate this without any real information. The result is confusion, conflict, and missed opportunities to connect.
Red Zone gives partners visibility into the cycle — not to control it, but to understand it. When you know what phase she's in, you stop taking things personally and start showing up the right way.
Enter the last period date and cycle length. Red Zone calculates phases automatically.
Ask the bot for the current status anytime. Get the phase, mood forecast, and advice on demand.
Automated alerts before the most difficult days of the cycle so you can prepare.
Members receive a morning Telegram message with the day's phase, mood, and advice.
Privacy first
Your cycle data is stored securely and never sold or shared with third parties.
No shame, no stigma
We treat the menstrual cycle as a normal biological reality — not something to hide or be embarrassed about.
Partnership, not surveillance
Red Zone is a tool for support, not control. Awareness should bring couples closer, not create pressure.
Simple by design
We deliberately keep the interface minimal. You shouldn't need a tutorial to understand what's happening today.
Red Zone was created by Denis — a developer who built this for his own relationship and realized other couples needed it too. The goal was simple: a clean, private tool that makes cycle awareness effortless for both people in a relationship.
The project is supported through Ko-fi memberships. If Red Zone helps your relationship, consider becoming a member — it keeps the app running and improving.
