DÆR-08 is a private cycle and mood tracking app designed for personal awareness and gentle reflection. Floating gently on water, a small white cloud keeps track of the moments you choose to record — your period cycle, your daily moods, and the small signals that shape your month. Log your period. Note how you feel. Watch patterns appear over time. It helps you notice how your moods may shift across different phases of your cycle and gently shows when your next period may be approaching, based on the entries you record and the cycle length you set. From time to time, your entries come together in short reflections using simple calculations, helping you look back and see patterns more clearly. Everything stays on your device — private and under your control. Nothing is sent to external servers. No accounts. No tracking. No ads. Just a calm little cloud watching over your rhythms, one month at a time. Terms of use: https://www.sunloft-studio.com/d%C3%A6r-08-terms-of-use
