Haloscan: Thyroid Lab Tracker
Track thyroid labs, symptoms and doses in a single place and generate a report for your appointment.
Haloscan is a thyroid tracking app for people with Hashimoto's or hypothyroidism. It keeps your lab results, your symptoms and your medication doses in one place.
Three things it's for:
Walking into an appointment with evidence so your doctor can't dismiss how you feel. The app generates a one-page report with your entire thyroid history and the questions you wanted to ask your doctor on top.
Keeping all your thyroid health data in a single place. TSH, Free T4, Free T3 and TPO antibodies from any lab, stored against that lab's own reference ranges, with units converted for you. Photograph a printout rather than typing it in. Symptoms logged morning and evening, doses and the dates they changed.
Spotting trends in your data and understanding why you feel he way you do. How your levels moved, how you felt in the same weeks, what changed after a dose adjustment, and which markers nobody has tested in over a year.
It started as a spreadsheet I built for my mother, who spent years being told her thyroid results were normal but feeling steadily worse with no way to show it. I made the same report for anyone who asked, for free, until I couldn't keep up. So I built it properly.
