About this app

Senuna Cycle is a calm, private place for your menstrual cycle. Log your period in seconds, see when your next one is likely, and keep a gentle diary of how you feel — all with your data kept on your own device.

PREDICT YOUR CYCLE
• See your predicted next period and current cycle day at a glance.
• A clear calendar shows your logged days, predicted period, and an estimated fertile window.
• Predictions work from day one using the cycle length you set, then sharpen automatically as you log more cycles.

A GENTLE MOOD DIARY
• Note how each day felt with a simple mood and a private journal entry.
• Look back over time and notice your own patterns.

SEE YOUR PATTERNS
• Trends show your cycle length over time, how long your periods last, and how your mood moves through the month.

CALM, PRACTICAL READS
• A small library of clear, supportive articles — easing cramps, understanding your cycle phases, riding out PMS, and knowing when something is worth raising with a doctor.

PRIVATE BY DESIGN
• Your cycle and diary data stay on your device. We never upload it.
• Optional app lock with your fingerprint or device passcode.
• Export a backup any time so a new phone doesn't mean starting over.

GENTLE REMINDERS
• Optional nudges before your period is due, when your fertile window is estimated to begin, if your period runs late, and a daily prompt for your diary.

MADE TO FIT YOUR DAY
• A home screen widget shows your cycle day at a glance.
• Light and dark themes.
• Available in English, Lithuanian, Russian, Polish, Spanish, French, German, Portuguese and Turkish.

Senuna Cycle is free, supported by ads.

Please note: Senuna Cycle is for tracking and awareness only. The fertile window is an estimate — it is not a method of contraception, and the app does not diagnose or treat any medical condition. If anything about your cycle worries you, please speak to a healthcare professional.
