Not worth it
Just purchased this app. It has an obnoxious clicking sound when pressing any button, and it cannot be turned off. Will be seeking refund.
Used to be great, but now terribly slow
Slower than 1987 real calculator, how possible
Moins bien qu’une autre application
J’avais l’application touch 11i. Bien mieux. Malheureusement d’un seul coup elle a arrêté de fonctionner. Celle application fonctionne mais pas très agréable. Impossible de la mettre verticale. De paramétrer le bruit des touches ….
Not functional
I have an iPhone 16. With the phone position sideways the calculator works excellent. My rotate vertical the image does not rotate. Also, there’s no access to settings as shown in the pictures. Lastly, it’s very difficult to close the app to move to something else. The normal swipe doesn’t work.
Excellent App and Sci Calc
This is an excellent app and HP 15C Scientific Calculator. I teach AP Calculus BC, and I use it often for my calculations. The user interface is clear and accurate, and the calculations are accurate. Highly recommended.
