# Blood Test Grapher vs Ruby Health

Blood Test Grapher and Ruby Health both sit at 4.2 stars, but that hides the real split: 76% of Blood Test Grapher's written reviews are positive against 23% of Ruby Health's. Blood Test Grapher also leads on iOS requirement (9.3 vs 15.0). Ruby Health's advantage is ads (none vs shown) and ratings volume (2K vs 29). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Blood Test Grapher sells 3 one-off in-app purchases and Ruby Health sells 5 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.2 for Blood Test Grapher against 4.3 for Ruby Health. That said, the two scores are not equally well evidenced: Ruby Health has 2K ratings behind it against 29, so its average is the more settled of the two.
