Landscape layout ?

After upgrading, so many features becomes unavailable because need to pay for them; while landscape layout (that allow number and functions in the same page) is not available anymore.
Is is still a good product, but lost his original fashion.

Gratis e senza ad

Gratis e senza gli ad che rovinano tutte le altre calcolatrici per iPad. Solo la calcolatrice di base (scientifica) è gratuita, le funzionalità più avanzate si pagano... e nemmeno poco: 10 euro. 5 stelle nonostante i pessimi colori usati (in tutti i temi) che mostrano i tasti tutti uguali, senza differenziarli.

One of the best apps of its kind.
Great combination of simplicity (as the late Edsger W. Dijkstra stated “a prerequisite for reliability”) and efficiency. Sooner or later a name change to ‘Calculator++’ could be appropriate 😊Keep up the great math works!
