Great SW and great support
Using this app on my iPhone 14pro max is very much like holding an HP28s in my hands. 😍 Had some problems with the german locale and the calculator and it was a) my fault b) solved by a nice mail in less than 24 hours

Not enough reviews to make a reliable assessment. The app needs more user feedback.
The price of Halcyon Calc is 199.00.

It is not easy to emulate the clamshell HP 28s model, starting with the keyboard and following with the algebra CAS commands. But this app has both tasks good implemented and deserves 5 stars.
Als ehemaliger HP-28S Besitzer finde ich die Tastenbelegung des HP 50g etwas krank und haber daher nach einer Alternative gesucht. Von allen Implementierungen im App-Store kommt Halcyon Calc dem Original HP-28S vom Look und Feel sicherlich am nächsten. Vielen Dank für die Entwicklung
Wer mit einem HP 28S gerechnet hat wird mit dieser App sehr zufrieden sein.
Loved this calculator and also the App. Nur why does the Icon have to be so ugly?
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.
