As many of you know, I recommend the Casio fx-260 solar as a trig calculator for navigation. It's cheap. It's durable. It operates in low light (no batteries). And it survives dunking in warm salt water. Years ago I wrote an emulator app. It's no big deal, but some of you are fans. There's a new version for Android phones and other Android devices available on my website:
clockwk-calc-2026-1.
You may need to adjust settings to accept "sideloaded" apps (apps from unofficial sources): read here.
This also exists for iPhones/iPads, but I have not gone through the effort of making it an official app in the Apple App Store, and Apple does not permit sideloading apps from other sources. If there's demand, P will make the effort. As I say, it's no big deal... just a calculator emulator.
