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
The clearest difference is review sentiment: ImmGen at 83% against PubMed Hub's 38%. ImmGen also leads on in-app purchases (none vs 7) and rating (5.0 vs 4.6). PubMed Hub's advantage is update cadence (every 8 days vs every 7 months) and ratings volume (342 vs 13). On price, ads and device support 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. PubMed Hub sells 7 in-app purchases, starting at $2.99 per year. ImmGen asks for nothing beyond the download.
ImmGen holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: PubMed Hub has 342 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 38% of PubMed Hub's.
ImmGen ships an update every 7 months, PubMed Hub every 8 days. The most recent releases landed on October 23, 2026 and November 1, 2026 respectively.
