Glink 5250 for iOS is an iOS-version of Gallagher & Robertson's best-selling terminal emulation program, Glink Professional Edition for Microsoft Windows. Glink 5250 is used to access applications running on IBM iSeries systems. Glink 5250 emulates all IBM 5250 terminals and uses the TN5250 protocol for communication with the host systems. Glink brings you a high quality and proven emulator for your iPad, iPhone devices and Mac computers with M1/M2 chip. Glink supports GlinkProxy, a server application designed to provide persistent host connections for Glink clients where the connection from the client device is unreliable.

GridCalc is a new kind of calculator for iOS. It combines Reverse Polish Notation with a visible grid so every step of your work is structured and reviewable. Instead of a hidden stack or opaque formula bar, each value and operation lives directly in the grid. Enter numbers incrementally. Apply operations. Reference prior cells. Change any upstream input at any time and see immediate recalculation. GridCalc is built for people who think in steps and care about clarity: • Engineers and developers working through exact calculations • Finance and trading professionals modeling scenarios on the go • Students learning RPN and structured problem solving • Anyone who wants spreadsheet-level visibility without spreadsheet friction Designed for fast, ad-hoc modeling on mobile, GridCalc keeps your work visible, precise, and easy to continue later.
