From its developer, TLA Systems, it appears… The app is “PCalc”. I’ve used it for years. Your choice of algebraic or RPN operation (RPN for me). Many built in keyboard layouts to choose from – basic to scientific – or you can craft your own. Scientific or engineering exponential format choice. A wonderfully extensive unit conversion feature. More…

This morning, as usual, I checked to see what app updates are available for my iPhone, and see one for PCalc:

“This app has been updated by Apple to display the Apple Watch icon. …”

Apple had previously bought the excellent “Dark Sky” weather app (and ended support for the android version). I open Dark Sky at least once virtually every day.

I wonder which app will be next.

Tangent alert: thanks for recommending Dark Sky. I’m probably going to buy it because wunderground is pretty lame now.

*sigh* Another app I'll lose if I switch back to Android

RealCalc is a good Android calculator app with all the common scientific calculator functions and stack RPN support.

Also, from what I can see, it doesn't look like Apple bought the app, just that they updated one of the icons to comply with their mandatory style for apps with Apple Watch support without involving the developer.

I have used both PCalc and RealCalc and like them both, however, I have pretty much switched over to using Free42 (an emulation of the HP-42S calculator) almost exclusively, as long time HP-41C user, I find Free42 more closely fits my assumptions of how a stack-based RPN calculator should work, key arrangement, etc. I believe it is available for most platforms, not just iOS and macOS.

I think that's what I used when I was on Android.

Keep up, dude

I mentioned this some time back when Apple announced they were going to put on-device-CSAM-scanning into iOS 15.

I they do: I'll be switching back to Android.

(TBH: I really don't much like Apple anymore.)

Yeah, I used to love Wunderground. Then IBM bought it, and it's been awful ever since.

Their recent MacBook Pro announcement was like a parody.

Their "revolutionary" product update is basically just undoing all the changes since about 2015 (they have added back the HDMI port and SD card reader, ditched the touch bar for normal function keys again, gone back to a MagSafe charging port, etc.).

Of course, they're not the only ones making those kinds of silly claims. A bunch of laptops are starting to move away from the widescreen and ultra widescreen displays to more square aspect ratios and there are a bunch of reviews and articles breathlessly promoting the revolutionary productivity benefits of going back towards the aspect ratios everyone was using 15 years ago.
