TablePlus VS Haloscan.co

Haloscan.co's answer:

Adults managing Hashimoto's thyroiditis, hypothyroidism or an underactive thyroid — including after a thyroidectomy or after treatment for Graves' disease — who take thyroid hormone replacement and want to know whether a dose is working.

The specific person it was built for has been handed a lab printout and a five-minute appointment and asked to make sense of both, often after years of being told results are "normal" while still feeling unwell.

It is not for clinicians. There is no practice management, no billing and no patient roster. The person holding the phone is the patient.

Haloscan.co's answer:

Haloscan is built for one condition rather than for health in general. It tracks a full thyroid panel — TSH, free T4, free T3, reverse T3, TPO and thyroglobulin antibodies — against the reference range your own laboratory printed, not a generic range, because laboratories differ and a number without its range means nothing.

The part no general tracker does: it puts your lab results, your daily symptoms and every levothyroxine dose change on one timeline, then builds a two-page summary for an appointment that is twelve minutes long. 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.

It also flags a blood draw if you take biotin, which can interfere with thyroid blood tests and is the kind of detail only a thyroid-specific app would know to warn about.

Haloscan.co's answer:

Most symptom trackers are built for any condition, so they track how you feel and stop there. Most lab trackers store numbers and stop there. Haloscan joins the two, which is the whole point: a thyroid result is only meaningful next to how you felt that month and what dose you were on.

Three practical differences:

• Photograph a lab report and the values are read off it. You confirm every one before anything is saved, and the photograph itself is never stored.
• The doctor report is printed black on white with every status stated in words rather than colour, so nothing is lost to a photocopier or to a reader who does not see red and green apart.
• Export every lab, dose and symptom to a spreadsheet at any time, with or without a subscription, and delete your account and everything in it from Settings. Your medical history is not a hostage.

Haloscan does not diagnose, does not treat, and does not tell you what your results mean. It shows your own data clearly so you can ask better questions of the person who does.

Haloscan.co's answer:

My mom has Hashimoto's. For six years she was told her labs were normal while she kept getting worse.

Her results were scattered across letters, portals and folders from different years, so nobody — including her — could see the shape of the thing over time. I built her one chart: every result on one timeline, every dose change marked, symptoms underneath, and a page at the front with three questions drawn from her own data.

Her next appointment was not a breakthrough. But her doctor noticed a pattern he had missed for years, and adjusted her prescription.

I made the same report by hand for anyone who asked, for free, until I could not keep up. Haloscan is that report, built properly.

Haloscan.co's answer:

• React Native 0.86 and Expo 57, in TypeScript, for iOS and Android from one codebase
• Expo Router for navigation, react-native-svg for the charts
• Supabase for Postgres, authentication and storage, with row level security so a person's health data is reachable only by them
• Supabase Edge Functions on Deno for everything the device must not decide, including subscription entitlement
• RevenueCat for subscriptions across the App Store and Google Play
• Anthropic's Claude for the wording of the doctor report, and Google Gemini for transcribing a photographed lab report. Neither model receives raw lab history or symptom logs
• PostHog for product analytics, off unless a person turns it on
• The marketing site is TanStack Start and React 19 on Netlify, with Plausible
