NiDa is a private journal and daily reflection app. The name means Night and Day. A calm check in each morning and night, to understand how you feel and grow a little every day. Write down your thoughts, track your mood, and NiDa listens and gently helps you go deeper. And there is Your Sky, your birth chart, to read as a mirror. No pressure, no streaks. Your journal stays on your device, and your reflections are created right on your phone. ABOUT THE APP Open NiDa whenever you need a quiet moment. Answer the day's gentle prompt or start writing. A small moon floats on every screen to take you anywhere in NiDa. Over time, NiDa shows you your patterns and how far you have come. YOUR SKY: YOUR BIRTH CHART, AS A MIRROR Every birth chart begins with one moment: the sky above the place you were born, at the hour you arrived. Your Sky draws it as a wheel of your planets, signs and houses, the aspects between them, and the four angles. Pinch to look closer. Tap any of them for a short, reflective read. Celestial Personality reads your Sun, Moon and Rising together, as one portrait. Your balance shows your elements and modes, and planets retrograde at your birth have their own read. Every read ends with a question, and "Reflect on this" opens your journal with it. Astrology as a mirror for noticing who you are, never a forecast. Not sure of your birth time? Choose a part of the day, and your rising is shown as an estimate. Read Chart for a Friend makes a birth chart card for someone you love; their details are never saved. Off until you choose it, under the Moon tab. REFLECT: YOUR DAILY JOURNAL Each day NiDa offers a prompt that fits your mood. Answer it, and NiDa asks one gentle question back, so a quick note can become a real moment of insight. When you write from Your Sky, your reflection remembers where you started. MOODS: SIMPLE MOOD TRACKING Log how you feel in seconds with a mood and a few tags. Every check in is followed by a kind, reflective question, and if you want it, a small suggestion that might help. INSIGHTS: SEE YOUR GROWTH NiDa quietly connects the dots across your entries and moods. See the themes you return to, revisit a moment from this day last month, and read the story of your journey, told in your own words. In your words, on Home, gathers everything you have written, day by day. Progress you can feel, never a streak to chase. MOON: A NIGHT AND DAY RHYTHM Follow the moon as a natural rhythm for your reflections. The moon calendar shows each day's phase as a realistic moon, with its old seasonal names and the sign the moon is moving through that day. Your own moods and entries settle onto the cycle over time, a calm way to notice how your days and nights unfold. A gentle rhythm to return to, never a forecast. AFFIRM: A KIND THOUGHT EACH DAY Keep a daily affirmation as a beautiful card you can save, revisit, or share with someone who needs it. RITUALS: COMFORT WHEN YOU NEED IT Browse a small library of cozy practices for grounding, rest, and gratitude. ONE TAP AWAY Widgets for your Home Screen, Lock Screen and StandBy bring tonight's moon, your affirmation, today's prompt, a check in, a ritual for tonight and Your Sky. Add NiDa to Control Center, or say "Check in with NiDa" to Siri. PRIVACY Private by design. No account, no sign in. Your journal stays on your device: your moods, notes and reflections are kept on your phone, not on our servers, and your reflections are created there too. Your birth details and your chart stay on your device. If you send feedback from Profile, your answers come to the NiDa team. Night and day, and the sky you were born under: NiDa is a space to return to. NiDa is for reflection and wellbeing. It is not medical advice or a substitute for therapy.
