Here's my professional opinion. Why aside from Excel/Google Sheets? What's special about blood test results? If you don't quite know how to make spreadsheets do what you want, it's probably best to just learn that. If you go for something else, the app you chose might go away in a couple years, for many reasons. Many developers don't like working on the same thing their entire life. Or some API gets deprecated; guess how often developers like to implement the same thing over and over?
