About
Haloscan is a thyroid tracking app for people with Hashimoto's or hypothyroidism. It keeps your lab results, symptoms and medication doses in one place.
Three things it's for.
Walking into an appointment with evidence. "I've been exhausted" is easy to wave away. The same thing with dates against it, next to the results from those months, is harder to. The app builds a two-page report with your history and your questions at the top.
Keeping your thyroid data together. TSH, Free T4, Free T3 and TPO antibodies from any lab, stored against that lab's own reference ranges. Photograph a printout rather than typing it in. Symptoms morning and evening, doses and the dates they changed.
Spotting trends. How your levels moved, how you felt in the same weeks, what changed after a dose change.
It started as a spreadsheet for my mother, who spent years being told her results were normal while getting worse. I made the same report for anyone who asked, free, until I couldn't keep up. So I built it properly.
