## TI-Nspire CAS CX and TI-89 Apps

Zoom Math apps don’t run on the TI-Nspire, except with the special 84 Plus keyboard installed. Zoom Math apps don’t run on the TI-89 either. If you want to run Zoom Math apps, you’ll need a TI-84 Plus (and not a CSE). If you own a TI-Nspire CAS CX, we recommend you visit TiNspireApps.com; if you own a TI-89, we recommend you visit TI89.com.
