There's others but I prefer Zohocrm because it works similar to Salesforce which is what I use for my full time job so it reduced my learning resources.My personal rule for online tools is that I have to be able to use it fluidly  between my laptop, iPad, android phone, or samsung tab.

For me it works on windows and Mac but not my android tablet.

Regardless of whether you're using iOS, Android or Windows (there aren't a lot of you), viewing user profiles should be much easier on your mobile devices as of today.In the coming weeks, we'll continue to make other parts of the site more friendly for mobile use, starting with the PM/conversation system and dashboard, so stay tuned!
