Siela vs Cycle Sister

Organize your day without juggling five separate apps. Siela brings your calendar, daily routines, notes, and optional cycle tracking into one calm, private space. It is built for women who want structure without pressure -- and cycle awareness without turning life into a medical dashboard. YOUR DAY, BEAUTIFULLY ORGANIZED See everything that matters on one screen: today's routines, upcoming events, cycle phase, and recent notes. No clutter, no noise -- just a clear view of your day. BUILD ROUTINES THAT ACTUALLY STICK Create morning, evening, or custom routines and check them off at your own pace. Siela never punishes you for missing a day. There are no streaks to break, no guilt notifications -- just a gentle system that welcomes you back every time. FLOW DAYS: CELEBRATE YOUR CONSISTENCY Complete 70% or more of your routines and watch your Flow Days grow. A rolling 7-day window tracks your momentum with a blooming flower visual -- a quiet celebration of showing up for yourself, not a punishment for falling behind. OPTIONAL CYCLE AWARENESS Track your cycle when it helps you. Hide it when it does not. Siela shows your current phase, predicted next period, and cycle length trends based on your own data. No overwhelming charts, no clinical language -- just awareness that fits naturally into your day. CALENDAR AND NOTES, TOGETHER Plan events in a clean calendar view and attach notes to any day. Keep thoughts, reflections, and reminders close to the moment they belong to. PRIVATE BY DESIGN Every piece of data stays on your device. There is no cloud sync, no account wall, no data collection. Your routines, your cycle, your notes -- they belong to you and only you. WHY SIELA FEELS DIFFERENT - One app replaces five: planner, habit tracker, cycle tracker, calendar, and notes - Private by design: all data stays on your device - No account required -- open the app and start - Czech and English from day one - Designed for daily life, not productivity guilt - Calm, elegant interface that feels like a personal journal IMPORTANT: Siela is a personal awareness and planning tool. It does not provide medical advice, diagnoses, or treatment recommendations. Cycle predictions are estimates based on your logged data and should not be used for medical decisions. Always consult a healthcare professional for medical concerns.
