What's New in FloodRoute

2.2

October 26, 2026

• Posting flooding is faster and more forgiving: the pin stays where you are, you get a few seconds to undo, and you can post a photo you took in the last hour straight from your library. • Delete your own posts anytime. • Swipe through flood photos, with each road's condition marked right on the photo. • Share a flood warning as just a picture, for Nextdoor and groups that remove links. Threads now gets the map card and the link. • Flood times are easier to read: every forecast and share card shows when the water peaks. • "King tide" now means what it should: the year's highest tides, like Thanksgiving week and the days around Christmas. When the bay runs above the tide tables, FloodRoute still forecasts the extra water street by street; it just doesn't call an ordinary high tide a king tide anymore.

Just what I needed

Great app that will help me navigate the flood days. Caught me too many times.

Response from developer

Thanks so much for the kind words and supporting my first ever iOS app!

Much Needed & Appreciated!

After the recent floods in Marin, I know I am quite happy to see this app having been developed, and I know many others will be as well. Looking forward to the expansion out to Oakland where I also spend a lot of time. So far, so good with the functionality. Offers a lot of helpful information in one place, and we will really get to test it out fully, next time the king tides do their thing….
