Everything in one place, and a report that speaks for you. Haloscan is for people managing Hashimoto's and hypothyroidism who have been told their results are "normal" while they still feel awful. ONE TIMELINE, NOT THREE Your labs, your symptoms and every dose change sit on a single chart. Pick any symptom and any marker and see how they line up: energy against TSH, brain fog against Free T3, how you felt in the weeks after a dose change. Patterns you can point at, in your own data, instead of a feeling you cannot put into words. THE REPORT Two pages your doctor can read in sixty seconds. • The questions worth asking, taken from your own results. • The trends behind them, with the chart for each. • Black on white, with every status stated in words rather than color, so nothing is lost to a photocopier or to a reader who does not see red and green apart. WHAT YOU TRACK • Every result against the range your own laboratory printed, with a link to what each test measures. • How you feel, in about thirty seconds, morning and evening. • Every dose and every change, with reminders at your times. • A flag before a blood draw if you take biotin, which can interfere with the test. WHAT IT IS NOT Haloscan does not provide medical advice. Always seek the advice of your doctor or another qualified health professional in addition to using this app, and before making any medical decision. Haloscan is not a clinic and does not replace your doctor. There are no consultations to buy and no courses. It does not diagnose, and it does not tell you what your results mean or what is causing how you feel. It shows you your own data clearly, so you can ask better questions of the person who does. YOUR RECORD IS YOURS Never sold, never shared with insurers or employers, never used to train AI. Export every lab, every dose and every symptom to a spreadsheet whenever you like. Free, with or without a subscription, and still yours if you cancel. Your medical history is not a hostage. SUBSCRIPTION Free to try for 14 days. After that, an annual or weekly subscription keeps your history and your doctor reports. Cancel any time in Settings. --- Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Terms of Service: https://haloscan.co/terms Privacy Policy: https://haloscan.co/privacy
