How many Apps can you download?

That depends on which calculator you have and which App titles you choose.

Your TI-73 Explorer™, TI-83 Plus, TI-84 Plus or TI-84 Plus Silver Edition calculator has "App spaces" that are chunks of memory into which you can load Apps. Some Apps take up only one space and other Apps take up to four. See how many App spaces your calculator has:

TI-73 Explorer - 12 App spaces
TI-83 Plus - 10 App spaces
TI-84 Plus - 30 App spaces
TI-84 Plus Silver Edition - 94 App spaces

The TI-89, TI-89 Titanium, TI-92 Plus, and Voyage™ 200 do not use App spaces, but do store Apps in Flash memory. The TI-89 and TI-92 Plus each have 702K of Flash Memory and the TI-89 Titanium and the Voyage 200 each have 2.7MB of Flash Memory.
