About RightCard
RightCard tells you which of your cards to use at any store and auto-adds the bank offers you'd forget to activate (Amex, Chase, Citi, Wells Fargo). It keeps rotating 5% categories straight so you don't have to remember them, and warns you before card credits and annual fees renew. No bank login, no account, no tracking — the Safari extension reads the offers page you're already signed into, and recommendations are computed on your phone, even offline. Honest numbers only. Free, no ads.
About El Niño
El Niño is a recurring warming pattern in the tropical Pacific that can influence weather around the world. This iPhone app turns live public NOAA data into a simple answer: is that warming signal building, fading or still uncertain? See what changed, where the warm water sits and how similar events unfolded before. A Home Screen widget keeps the latest complete update nearby. Upfront paid once, with no account or subscription. Independent context, not a forecast or official guidance.
