Setup
Installing on iPhone and iPad
Use the App Store build, then configure the model and load presets from inside the app.
- Open the App Store and install Calc-U 59.
- Launch the app and choose the calculator model in the toolbar or Settings.
- Use the preset file picker for .ti59, .ti58, or .ti58c files.
The mobile build follows the standard iOS app flow: there is no extra setup after install.
On iPhone and on iPad in portrait, the calculator uses the same key layout as the app screenshot; on iPad in landscape, the layout mirrors the Mac view.
