Complete list of apps?

Glad to have stumbled upon this community! I am curious about phone applications for SuiteCRM. I just completed my install on Hostgator, which was more difficult than it should have been! Are there other apps than the following?:


I would prefer as low as cost as possible. Will I be able to have the app synch with my server and Outlook?

Thanks in advance! I know this is a common question that I Googled. Google has turned into marketing that top advertised options and I love to hear other views than the paid ones! Thanks!
