Selene Moon Cycle

Read full description

Selene is a daily guide that combines your menstrual cycle with the rhythm of the moon. Every day, Selene shows you where you are in your own cycle and what that phase brings — physically, emotionally, and energetically. At the same time, it tracks the current moon phase, from the intentions of the New Moon to the release of the Full Moon. These two cycles have always moved together. Selene helps you read them both. WHAT SELENE SHOWS YOU EACH DAY · Your current cycle phase — menstruation, follicular, ovulation, or luteal · What that phase means for your energy, mood, and body · The current moon phase and its emotional tone · Themes and intentions for each phase of the lunar cycle · Moon in Sign (optional unlock): which zodiac sign the moon is in, how it affects your energy, and what it means for your exact cycle phase MOON IN SIGN The moon moves through a new zodiac sign every two to three days — and it changes the quality of everything. Moon in Sign is a one-time unlock that gives you daily insight into which sign the moon is in and how it connects to where you are in your cycle. No subscription. Yours forever. DESIGNED FOR WOMEN WHO WANT TO UNDERSTAND THEIR RHYTHM Selene does not tell you what to do. It reflects what is already happening — in your body, in the sky — and lets you make sense of it yourself. Minimal, quiet, and personal. · No account required · No subscription for the core app · Cycle tracking stays on your device **Your cycle, your four phases:** Menstruation, Follicular, Ovulation and Luteal — each with its own energy, archetype and guidance for the day. **Moon phase guidance:** Eight lunar phases explained in plain language. Know when to start, when to push and when to rest. **Cycle and moon alignment:** Selene shows how your personal cycle relates to the current moon phase — the White Moon cycle, the Red Moon cycle and everything in between. **Completely private:** Everything stays on your device. No gathering of data.

The call

The clearest difference is ads: Selene Moon Cycle at none against DogKoo's shown. DogKoo's advantage is update cadence (every 4 days vs every 10 days). On price, in-app purchases, device support and iOS requirement there is nothing between them.
