App designers have choice -- Apple's iOS, RIM's BlackBerry OS, or Google's Android. That's because the different devices each have their own operating systems. Until now, Apple was the obvious choice. But the others are beginning to catch up.
| Apple | RIM | ||
| Number of apps | 286,000 | 100,000 | 14,000 |
| Platform market share | 24% | 21% | 37% |
