CYCLE-AWARE CALENDAR CycleSync helps professional women align their work schedules with their natural menstrual cycle phases. Instead of fighting through low-energy days, you get smart suggestions to move demanding meetings to days when your focus and energy peak. WORK WITH YOUR RHYTHM, NOT AGAINST IT Your cycle isn't an obstacle. It's a compass. Menstrual Phase (Winter) Rest and recovery. Reschedule high-stakes meetings. Follicular Phase (Spring) Rising energy. Schedule creative work and planning. Ovulation Phase (Summer) Peak performance. Take on negotiations and leadership. Luteal Phase (Autumn) Focused wind-down. Finish projects and organize. SMART RESCHEDULING CycleSync connects to your calendar and automatically detects: • Events on heavy-flow days • Events on rest-phase days • Dense meeting days during focus phases (3+ events) One tap on a conflict card opens the Time Slot Picker. Your available slots on better days are pre-calculated. Reschedule in seconds. An undo option gives you 10 seconds to reverse. RULES, NOT GUESSWORK. The recommendation engine is rule-based: 1. Your cycle history predicts your phase for any date. 2. Your phase preferences determine focus or rest classifications. 3. Your calendar events are flagged when they conflict with your classifications. 4. Available slots on recommended-phase days enable one-tap rescheduling.

Indigo 22 makes hypnosis audio for one person at a time. Every session in your library is written around your name and your life, then built and delivered just to you. There is a specific kind of tired that sleep doesn't fix. You know the one. You slept a full night and still woke up braced, like your body rested but your nervous system stayed on shift. This is the app for that. Indigo 22 is where your personalized hypnosis and meditation audio lives, so the calm you already have is always one tap away. Log in, press play, and let the sessions built around your name meet you wherever you are: the 2am spiral, the tight chest before a hard meeting, the long exhale as you finally fall asleep. WHAT IT IS Indigo 22 holds the guided hypnosis and meditation sessions made for you. Open the app, press play, and listen. That is the whole thing. No feeds to scroll, no noise to filter, just your audio, ready when you are. HOW IT WORKS - Log in with the email and confirmation number from your order. - Your library loads with your sessions already inside. - Press play. Listen with headphones or out loud. - Download for the plane, the car, the campsite - anywhere offline. Morning, night, or the middle of a hard afternoon, there is a track for it: - A daytime primer to start the day a few degrees calmer. - A nighttime reset for the nights your brain will not clock out. - A short reset button for the ten seconds you need one. WHO IT IS FOR For the overthinker who has tried the apps, the videos, and the breathing thing a friend swore by, and quietly decided nothing works for her. It was not you. Generic audio gets filtered out as background noise. This is audio built around you, by name, about your actual life, so it gets through. WHY IT IS DIFFERENT Indigo 22 was built by Lori, a Certified Hypnosis Practitioner and lifelong engineer who has the anxious brain she designs for. She explains why the audio works instead of asking you to just believe it: your name slips past the brain's noise filter, a long exhale eases the nervous system, and gentle tones guide you toward the calm, open state your brain usually only visits as you fall asleep. It is rooted in science, and it is built to be used. And an honest note, because that is the brand: if a walk outside and a few deep breaths are handling things, keep doing that. This is for the days the free stuff stops reaching. NO GUILT, EVER Missed a few days? Nothing is ruined and there is no streak to lose. Repetition is the mechanism, not perfection. Press play tonight. That is the whole assignment. A NOTE ON WELLNESS Indigo 22 offers guided audio for relaxation and everyday stress. It is a general wellness app, not a substitute for professional medical or mental health care, and it does not diagnose or treat any condition. Press play. Your nervous system will thank you.
