About Hazel: Hashimoto's Thyroid Log
Make sense of your Hashimoto's. Hazel turns your symptoms, labs, meals, and supplements into a clear picture - so you can finally see what's helping you feel better. Living with Hashimoto's often feels like a guessing game. Flare-ups happen without warning. Diet, stress, sleep, and lab results all matter - but tracking them across endocrinologist visits, supplement bottles, and meal photos on your phone is exhausting. Hazel is built for the work between appointments. WHAT HAZEL DOES - Ask Hazel anything, by chat or voice. Your AI companion knows everything you've logged: meals, supplements, labs, symptoms. It surfaces patterns you'd miss, like "your last three brain fog spikes came after low-sleep nights". - Track symptoms and supplements in seconds. Log fatigue, brain fog, mood, body pain, and the supplements you take, with reminders that fit your routine. - Snap your meals. Hazel identifies what's on your plate and learns which foods correlate with how you feel over time. Built for AIP, anti-inflammatory, and gluten-free patterns. - Log your labs. TSH, T3, T4, anti-TPO, free T4, and antibodies - visualized over time so you can see whether your treatment plan is actually working. - Doctor-ready reports. Export a clean PDF summary of your last 90 days - labs, symptom trends, interventions tried - to share with your endocrinologist or functional medicine doctor. - Tools for the journey. Guided meditation, NSDR (Non-Sleep Deep Rest), and educational content rooted in published research. HOW IT WORKS 1. Log daily - symptoms, meals (photo or manual), supplements, sleep. Takes under a minute. 2. After a week, Hazel surfaces what's trending better and what needs attention. 3. After three months, your labs and lifestyle tell one story - and you can share it with your doctor. WHO HAZEL IS FOR Hazel is for the person who has been diagnosed with Hashimoto's thyroiditis or sub-clinical hypothyroidism and wants to do the lifestyle work alongside their medication - the AIP diet experiments, the supplement protocols, the stress management, the patient self-advocacy. If you've ever sat in a doctor's office trying to remember what changed since your last lab draw, Hazel is for you. SUBSCRIPTION A free trial is available so you can explore all features before committing. Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your Apple ID settings. NOTE Hazel is a tracking and educational tool, not medical advice. All information is meant to support - not replace - your conversations with your healthcare provider. Always consult your endocrinologist before making changes to your medication or treatment plan. START YOUR FREE TRIAL Download Hazel, log your first symptom, snap your first meal, and start connecting the dots.
