Pollen Sense in the news, plus product and science updates.

March 27, 2026

We’ve been spending a lot of time reviewing feedback, reading survey responses, and looking closely at how people are using Pollen Wise. One common thread amongst the feedback and survey responses stuck out: people want the app to feel easier to understand at a glance, and more helpful in answering the question, “What should I care about right now?” That thinking shaped this latest update. This is a major refresh to the Pollen Wise home screen, and while we know there is still more to improve, this update is an important step. We’re continuing to build, refine, and learn, and your feedback is a big part of what helps us decide where to go next.
