# Histamine Tracker vs Code Red

The clearest difference is monetization model: Histamine Tracker at freemium against Code Red's subscription. Histamine Tracker also leads on ratings volume (37 vs 1) and iOS requirement (15.1 vs 26.5). Code Red's advantage is ads (none vs shown) and rating (5.0 vs 4.7). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Histamine Tracker sells 4 in-app purchases, starting at $9.99 per month and Code Red sells 1 in-app purchase, starting at $19.99 per year. Whichever you choose, the download price is not the number that matters.

Code Red holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Histamine Tracker has 37 ratings behind it against 1, so its average is the more settled of the two.
