What's New in Halcyon Calc Lite

4.3

May 6, 2026

In this version, the size of the font in the display area will grow or shrink based on the user's "Text Size" setting in the "Display & Brightness" section of the system settings. So, if you have your text size increased from default, you should find that the text in the display of the calculator will also be somewhat larger and easier to read. If you have the setting low so that your text tends to be smaller than default, you should find that the text in the display of the calculator will also be smaller and show more content on your screen. Let us know if the behaviour is not to your liking and we can tweak this behaviour in future versions.

Trigonometry

I love the nice clean look of your calculator. How ever I can’t make head nor tail of your trig functions. Are you using the traditional functions? For example, it keeps telling me the sin of 45 deg is 0.8509 and cos 45 is 0.5253. How are you getting this?

Top Emulation des legendären HP 28-S.
Einzig störend, dass sich der Tastenton nicht abstellen lässt.

La vieja 28C vuelve a la vida

Todavía tengo en funcionamiento mi vieja 28C. Tener esta app permite darle nueva vida en lugar de estar aparcada en un cajón. Llegué a dominar bien la programación RPN (tipo FORTH) de esta calculadora y se echa de menos todo el potencial que permitía. Esperemos que la app con el tiempo la incorpore.

Toller programmierbarer Rechner

Ich habe einen echten HP-28S und diese APP ist die beste Umsetzung für iPhone und iPad im AppStore. Sehr gut zu bedienender UPN-Rechner mit vielen Funktionen des Originals.
