Siela vs Evo Cycle

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.

Evo Cycle is a period and cycle tracker that learns your rhythm from your own days, never from averages. LOG IN SECONDS Mark period days with flow, color and detail. Add how you feel: mood, energy, symptoms with intensity, and a private note in your own words. Weight, sleep and water ride along in the same quick check-in. PREDICTIONS THAT ARE HONEST Your next period, fertile window and cycle position are computed from what you actually logged. Solid means you told us, dashed means we predict. Every estimate says what it is based on, and it sharpens with every cycle you track. THREE WAYS TO TRACK Tracking your cycle, trying to conceive, or pregnant. Conceive mode adds basal temperature, cervical mucus and LH tests, and a confirmed ovulation corrects the prediction. Pregnancy mode pauses predictions and counts your weeks instead. SEE YOUR PATTERNS Once Evo has seen enough of your cycle, insight cards connect how you feel to where you are in it: when your energy peaks, when your mood tends to dip, how your phases shape your week. Build a report you can take to a doctor and export it as a PDF. WORKS WITH APPLE HEALTH Sync both ways. Periods and symptoms you logged in other apps import in, and what you log here writes back, so your health record stays whole. Sleep and steps come along automatically. ON YOUR WRIST AND HOME SCREEN Widgets show your cycle day and countdown at a glance, the Apple Watch app logs a period from your wrist, and you can ask Siri when your next period is. PRIVATE BY DESIGN Lock the app with Face ID. Keep history only as long as you choose, and delete everything from inside the app, no email required. Your health data is never sold and never used for advertising. Reminders are discreet by default: nothing on your lock screen names periods or fertility unless you want it to. MAKE IT YOURS Four color themes, a designed dark mode, gentle reminders at times you pick, and 13 languages. Evo Cycle predictions are estimates for planning, not a contraceptive method and not medical advice.
