BloodTrends and HealthViewer both keep your lab results on your own device rather than a company’s servers. BloodTrends is a small, inexpensive iPhone and iPad app that reads lab PDFs and charts your biomarkers. HealthViewer is a desktop app for Mac and Windows that pulls results from patient portals as well as PDFs. We make HealthViewer, so we have tried to be specific about where BloodTrends is the better choice.
Where BloodTrends is stronger
- It costs almost nothing. BloodTrends is free, and Pro is $0.79 a month or $4.99 a year. HealthViewer is $24.99 once, after a 7-day trial.
- It is on your phone. BloodTrends runs on iPhone and iPad, and on Apple Silicon Macs as its iPad app. HealthViewer’s free phone app, on Android now with iPhone to follow, only views results you added on the computer.
- It is simple. Upload a PDF, and BloodTrends finds the biomarkers, charts each one, and sums up what improved, what held steady, what is new, and what is out of range. Its AI report reader summarizes a report in plain language.
Where HealthViewer is stronger
- It runs on Windows. BloodTrends is Apple only.
- It connects to patient portals. HealthViewer fetches results from Epic, Oracle Health (Cerner), athenahealth, and eClinicalWorks portals. BloodTrends works only from PDFs you upload.
- It reads more than PDFs. Along with lab reports from Quest, Labcorp, Mayo, MyChart, and others, HealthViewer imports CSV, FHIR, and C-CDA files, and device data from Apple Health, Dexcom, and Withings.
- It tracks more around the results. Medications appear as start and change markers on each test’s chart, next to your journal notes. HealthViewer also keeps vaccinations, procedures, vitals, and documents such as imaging reports, and prints an Appointment Prep report for your next visit.
- Your data is an encrypted file you control. Everything is in one file, encrypted with your password, that you can back up, move, or open on another computer. BloodTrends keeps data on the device; its listing does not describe encryption, backup, or export.
- Profiles for the family. One HealthViewer license covers a separate encrypted profile for each person on your computer. BloodTrends does not mention profiles.
