Hello! My name is John, and I am the developer of BloodNumbers.

BloodNumbers is an iOS app for tracking your blood counts on your iPhone or your iPad. It’s designed to be most useful for blood disease patients who want to keep track of all their blood test results, from multiple sources, in one convenient, portable, and secure place.

I developed BloodNumbers because I was not satisfied with any of the existing ways to track blood counts.

One existing way is to simply log into the Electronic Health Record (EHR) portal associated with your healthcare provider. That will give you your test results. But you may only see results from that provider. If you’ve also had tests via another provider it may not be possible to see those in the same place (you might have to log in to multiple portals). This makes it more difficult to observe changes over time. Another thing I did not like about viewing my results in the EHR is the poor quality of data visualization presentation, via charts or other types of data visualization. EHRs are slowly getting better at this, but I wanted to do better.

Some healthcare providers now share your data from their EHR to Apple Health Records. If you use an iPhone, and have opted in to Apple Health Records, then you may be able to see some of your results in the Health app on your phone. This works great. Unfortunately, many healthcare providers do not yet share their data to Apple Health Records, so you don’t see the full picture here.

As a result of these limitations, many people use a spreadsheet to track their results, manually copying each of their test results from various sources, into the spreadsheet. Spreadsheets are great for keeping track of data, and they also provide a lot of flexible charting features. This is what I was doing before I developed BloodNumbers.

BloodNumbers will accept data via a variety of sources: manually entered, imported from your spreadsheet, imported from Apple Health Records, or imported from various EHR systems.
