6 to 8 years. That is the average wait for an endometriosis diagnosis, and most of that time is spent trying to convince someone that what she feels is real. Made for your cycle. Built for endometriosis. Created by accredited naturopath and nutritionist Katie Rice to help you track your symptoms, understand your cycle, and be taken seriously at appointments. SYMPTOM-SAVVY CYCLE TRACKER This is not a generic period tracker. Every symptom you log, pain by location and type, digestive and bladder symptoms, fatigue, mood, brain fog, medications and supplements, builds a clear picture your medical team can act on. The more you record, the harder you are to dismiss. CYCLE PREDICTIONS See predicted period and ovulation dates based on your own cycle data, not a 28-day assumption. Your predictions get sharper as your history grows, so you can plan ahead. FLARE MODE When you are in a flare, you do not need more information. You need support, right now. One tap opens guided breathing, a soothing heat tip, a nourishing recipe, and a one-tap message to your support person once you have saved a contact. Built for the days when you just need to get through it. PRACTITIONER EXPORT A clinical report your GP can scan at a glance. Symptom patterns, cycle summary, medication correlations and your full daily log. You choose the date range, add your own notes, and walk in prepared. YOUR WEEK IN REVIEW A weekly summary of what your body has been telling you. Check-in streak, top symptoms, mood trends and notable patterns. PERSONALISED INSIGHTS After about two cycles of logging, see your own patterns. Which days are hardest, how your body responds to food and supplements, and mood trends by cycle phase. Every insight is explained in plain language, not medical jargon. SUPPORT CARDS Like having a naturopath in your pocket. Support Cards cover the most common endometriosis symptoms and every phase of your cycle, written by an accredited naturopath and nutritionist, evidence based, and focused on what you can actually do. OVULATION LOGGING Log your ovulation day and symptoms so your predictions reflect your actual body, not an average. ANTI-INFLAMMATORY RECIPES + MEAL PLAN BUILDER Simple, nourishing recipes created by an accredited naturopath and nutritionist to support your body. Plan your week in a few taps. A PRIVATE NOTE ON EVERY CHECK-IN Add a private note to any daily check-in and look back on them day by day. Capture how you are really feeling in your own words, and walk into appointments ready. BREATHING FOR THE HARD MOMENTS Guided breathing practices to help you feel calmer and more in control when pain and stress hit. DAILY AFFIRMATION A gentle daily reminder that you are not alone. YOUR DATA STAYS YOURS Everything you log is stored locally on your device and stays private. START FREE. GO DEEPER WHEN YOU ARE READY. Core tracking is free: your daily check-in and symptom tracking, cycle tracking and predictions, ovulation logging, a daily affirmation, and a selection of support cards and breathing patterns. When you are ready for more, a subscription unlocks all support cards, the full flare toolkit, recipes and meal plans, your personalised insights, Your Week in Review, and Practitioner Export. Every subscription starts with a 3-day free trial. Cancel anytime before the trial ends and you will not be charged. Payment is charged to your Apple ID at confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the period ends. Manage or cancel anytime in your Apple ID settings.

Verdict
The clearest difference is ads: Stack at none against Her Herbs's shown. Stack also leads on update cadence (every 3 days vs weekly). Her Herbs's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 17.0). On price and in-app purchases there is nothing between them.
