Explore gene expression levels in different mouse and human immune system cells. Start by entering a gene name (or alias) in the search bar to see a list of hits you can swipe through. Searching will display a "heatmap barcode" that shows how hot or cold expression of that gene is across different immune system cell lineages (B cells, T cells, Myeloid cells, etc). Toggle between 3 different datasets: mouse RNA-seq, mouse microarray, and human RNA-seq. Press down on a cell lineage icon to see the same expression data visualized as a bar chart. Use the settings menu in the top right to toggle between a log and linear axis. In the microarray data, low expression values are partially occluded. Back on the main "heatmap barcode" screen, if you instead press the "Show related genes" button, you'll see a "gene constellation" view. This shows its most correlated genes within certain population groups. By default, correlation is shown with respect to key populations — these are key populations across the entire immune system. Please reach out to immgen@gmail.com for feedback or feature requests! The data are generated by the Immunological Genome Project, an international consortium supported by the National Institutes of Health (NIAID).

Verdict
ImmGen and IDSA Practice Guidelines both sit at 5.0 stars, but that hides the real split: 83% of ImmGen's written reviews are positive against 0% of IDSA Practice Guidelines's. IDSA Practice Guidelines's advantage is ratings volume (559 vs 13). On price, rating, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
ImmGen holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: IDSA Practice Guidelines has 559 ratings behind it against 13, so its average is the more settled of the two. Written reviews point the same way: 83% of ImmGen's written reviews are positive against 0% of IDSA Practice Guidelines's.
Both ship on a similar rhythm, roughly every 7 months. The most recent releases landed on September 21, 2026 and September 28, 2026 respectively.
