YSK - You can save mobile.weather.gov to your phones Home Screen and avoid the adds and bloat of other weather apps. https://mobile.weather.gov/

“Why YSK: Many paid and unpaid apps get their information from the National Weather Service (NWS). This information is freely available and paid for though taxes, which the other companies try to profit off of. Skip the BS and just go to the source. It might not be the most polished website, but it’s easily navigable (has an old iOS feel to it).

I can’t give a guide for android users, but for iPhone, open safari and head to “mobile.weather.gov”. Once the website is loaded, click the share icon on the bottom middle of your screen, and then select “add to Home Screen”.
