Touch Fin RPN is an RPN financial and scientific calculator that implements most features of the industry-standard HP-12C, including programming functions.
It also implements a scientific RPN flavor that implements most functions of the beloved 11C. And even more flavors (10C-like, 16C-like) can be purchased within the app.
デベロッパの回答 、 The "10" (Scientific Basic) flavor is offered only in purchasable+ad-free model, so we could not understand what is the problem. Feel free to write to stendec@stendec.io or contact us via facebook.com/rpnemulators for support.
